058ef0dc98 Merged fixes to the osg::GLExtensions function pointer code from Stefan Huber,
and a fix to osg::State's secondary color code from Bob Kuehne.

Moved the body of the getGLExtensionFuncPtr() into the header to help out
support for Windows mapping of different OpenGL extensions function ptr per
dll.

Robert Osfield
22d54f05e4 Added DOFTransform, MatrixTransform and PositionAttitudeTransform to NodeVisitor.
Added osg::Matrix/Quat::makeRotate(angle1,axis1,angle2,axis2,angle3,axis3) and
osg::Matrix::rotate(angle1,axis1,angle2,axis2,angle3,axis3) method.

Made osg::Matrix/Quat::makeRotate(heading,pitch,roll) and
osg::Matrix::rotate(heading,pitch,roll) all deprecated API.

Fixed the Quat*Quat & Quat*=Quat multiplication methods so that they multiplied
in the correct order - they were reversed originally due to the Quat code being
based on code example which used the v' = M v ordering, rather than the OSG's
v' = v M ordering.

Changed the ImpostorSprite to use LINEAR,LINEAR for min and mag filters for the
impostor texture.
2002-08-16 15:14:43 +00:00
Robert Osfield
7dfefaf67f Added new osg::Texture::SubloadCallback, and getNumMipmapLevels() to osg::Texture

to animate the loaded model.
2002-08-12 17:40:36 +00:00
Robert Osfield
29490a8c1c Updates to DOFTransform so that its overrides the traverse() and compute*() methods
rather than depending upon callbacks for animating and compute matrices.  Merged the
put/inverseput code between Sasa's and Ferndinand's DOF code.

From Bora Utka, Added support to osg::Sequence/OpenFlight AnimNode to the flt plugin.
2002-08-12 13:42:43 +00:00
Robert Osfield
7010c1c4f8 Removed dependency of the new osg::DOFTransform and osg::Sequence Node's
on osgUtil by implementing a NodeVisitor::VisitorType enum, and associated
g/setVisitorType.  This allows callbacks to querry the visitor/traversal
type without doing down cast's to specific visitor subclasses such as
osgUtil::AppVisitor/CullVisitor.

Robert Osfield
d9b7b13bd3 Changed the Geometry::setVertexArray and GeoSet::setCoords so that they
call dirtyBound() instead of reseting the local bound flag, this ensures
the updates are propagated upwards through into the parents.
2002-08-08 11:27:11 +00:00
Robert Osfield
b9b013e15b Changed the support for anisotropic filtering in osg::Texture so that it
is now controlled via the setMaxAnisotropy(float) method, and is set up
independently for the mag filter mode, which it previously was done.
2002-08-07 15:52:24 +00:00

the OpenFlight DOF transform nodes.
2002-08-05 15:07:18 +00:00
Robert Osfield
fd788daa69 Added support to StateAttribute/State to support PROTECTED flag for modes and attributes
so that they cannot be overriden from above via the OVERRIDE flag.  This is
useful for things like manipulators that have handles display in the scene, you
might want to prevent their state being affected by other overriding of
light, wireframe modes etc.

6b59f66d80 Checked in new methods for setting up texture subloading, these allow the
user to control which parts on an image are subloaded from, and how big
the initial texture is.
2002-07-28 23:28:27 +00:00
Robert Osfield
05472135b0 Added set/getUnrefImageOnApply() methods and associated flag and
code in Texture::apply() to set the _image to 0 on apply.  Note,
this will only work when you have a single graphics context, as
with multiple graphics contexts one can't delete the image after
the first apply, as there will be more than one texture object to
update.

2002-07-19 14:19:49 +00:00
Robert Osfield
3cba9a52ef Updates NEWS file for 0.9.0 release.
Added default computeBound() implementation to osg::Drawable which uses
a PrimtiveFunctor to compute the bounding box in a generic way, that
will work for all Drawable subclasses that implement the accept(PrimitiveFunctor&).
2002-07-18 22:35:54 +00:00
Robert Osfield
34be82c1ee Moved get/setUserData from osg::Node into its superclass osg::Object to
allow other subclasses to add their own custom data.
2002-07-18 19:41:52 +00:00
Robert Osfield
ff8b4c001d Rewrote the osg::Drawable::AttributeFunctor and PrimtiveFunctor to make
them more consistent with each other. This does mean an API change, so
dependanct code in the OSG has been updated accordingly.
2002-07-18 15:36:14 +00:00
Robert Osfield
8036901ea1 Rewrote osg:Statistics so that it is PrimitiveFunctor as is now completely
decoupled from osg::Drawable.  The Drawable::getStats() virtual method
no longer exists.

Updated the Viewer to use the osg::Statistics incarnation and reformated stats
to clean it up.
2002-07-18 14:20:01 +00:00
Robert Osfield
7a8eeb3c92 Converted the osg::Material::set/getShininess option to use the standard
OpenGL range of 0.0 to 128.0 instead of the previous normalised shiniess
range. This brings it inline with the way the rest of the OSG uses a
1 to 1 mapping to OpenGL.

Converted the various loaders to use the new range, which is almost all
cases was simply removing the /128.0f which was required before!
2002-07-18 09:55:30 +00:00
Robert Osfield
09bdb10af5 Various fixes to the flt loader, and knock on changes to the osgUtil::Optimizer
to better support removal of seperate osg::Geometry instances where they

e280b50d31 Added osg::UByte4 class, which can be used to represent packed colors.
Changed osg::UByte4Array across to use the new osg::UByte4 class rather
than a GLuint as do previously.

Cleaned up some of the paramters in osg::Vec4.
2002-07-15 22:18:47 +00:00
Robert Osfield
db892e6bfe Added State::disableTexCoordPointersAboveAndIncluding( unit ) method so that
all unsed texture units can be turned off simply within Drawables such
as Geometry and GeoSet. This can be used to prevent bleed of arrays from
one object to the next - which can cause crashes.
2002-07-15 10:03:59 +00:00
Robert Osfield
db888b191c Conveted GeoSet to use the new state::set*Pointer/disable*Pointer methods
to keep the current state valid.

d87d27b749 Added MatrixTransform header and source. 2002-07-12 21:08:19 +00:00
Robert Osfield
6f392cdbfa Ported distribution across to use the new osg::MatrixTransform and osg::BlendFunc
class instead of osg::Transform and osg::Transparancy respectively.
2002-07-12 18:12:01 +00:00
Robert Osfield
8128265e09 Have added a #define USE_DEPRECATED_API to include/osg/Export, and
various
osg header and source files to optional compile in deprecated parts of
the
OSG API.

Have renamed osg::Transparency osg::BlendFunc to bring it in line with
the
rest of the OSG's StateAttribute classes which are named after their
OpenGL counterparts.  include/osg/Transparency still exists and is
simply
a typedef to BlendFunc and is enclosed in a #ifdef USE_DEPRECTATED_API
block.

The matrix methods in the osg::Transform class have been
moved/replicated in
a osg::MatrixTransform sublcass from osg::Transform.  The old matrix
functionality is still present in the osg::Transform class but is guard
by #ifdef USG_DEPRECATED_API blocks.  One should now think of
osg::Transform
as being a Transform Node base class.  MatrixTransform has all the
functionality of the original Transform class, so should be used
instead.

Robert Osfield
c4c97a0f64 Moved the code referencing osg::BoundingBox::isValid() and
osg::BoundingSphere::isValid() across to use the valid() methods, the later
being more consitent with other classes such as osg::ref_ptr<>.
2002-07-11 14:32:21 +00:00

Robert Osfield
9574ce97d2 Updated TODO list.
Converted AnimationPath so it is now subclassed from osg::Transform::ComputeTransfromCallback()
so that it can be directly attached to the scene to move objects about.

Changed the osg::SateSet::setGlobalDefaults() so that is sets GL_DEPTH_TEST
to ON.

Added guards and creation of default helper classes in osgGLUT::Viewer and
osgUtil::SceneView so that sensible defaults are used when no settings
are used of osg::State/StateSet,osgUtil::RenderStage/RenderGraph/CullVisitor.
2002-04-21 22:05:26 +00:00

the assert's better.
2002-04-17 09:48:19 +00:00
Robert Osfield
7836540bb3 Added osg::Image::setPixelFormat(..) and setInternalTextureFormat(), and
renamed osg::Image::pixelFormat(), internalTextureFormat(),dataType() to
osg::Image::getPixelFormat() etc.  These changes are to bring it more
into line with the style of the rest of the OSG.

Updated the rest of the distribution to take account for these names changes.
2002-04-16 14:57:39 +00:00
Robert Osfield
f8340f9ef5 Removed the cached matrices from osg::Camera, so that
osg::Camrea::getModelViewMatrix() and osg::Camera::getProjectionMatrix() are
calculated on the fly.  Removed various redudent methods, including the
project and unproject methods which are better supported within osgUtil::SceneView.

Added a computeWindowMatrix() method to Viewport, to make it easier to construct
a MV*P*W matrix for converting local coords into screen coords and visa versa.
Converted SceneView and CullVisitor to use this new method.

341ffb2361 Further work on cleaning up SceneView and Camera, in particular moving strereo
support out of Camera and into SceneView. Also enabled the option to set the
projection and modelview matrices directly on SceneView thereby removing the
dependance on osg::Camrea to control the view of the scene.

a44efe01bb Fixes for Win32 build 2002-04-12 09:53:39 +00:00
Robert Osfield
6ed233d0d2 Added DataVariance enum and set/get fields to osg::Object to help identify
which objects have values that vary over the lifetime of the object (DYNAMIC)
and ones that do not vary (STATIC).  Removed the equivalent code in
osg::Transform, StateSet and StateAttribute, as these are now encompassed
by the new DataVariance field.

Removed MatrixMode enum from Matrix, and associated fields/parameters from
osg::Transfrom and osg::NodeVisitor, since MatrixMode was not providing
any useful functionality, but made the interface more complex (MatrixMode
was an experimental API)

Added ReferenceFrame field to osg::Transform which allows users to specify
transforms that are relative to their parents (the default, and previous behavior)
or absolute reference frame, which can be used for HUD's, camera relative
light sources etc etc.  Note, the view frustum culling for absolute Transform
are disabled, and all their parents up to the root are also automatically
have view frustum culling disabled.  However, once passed an absolute Transform
node culling will return to its default state of on, so you can still cull
underneath an absolute transform, its only the culling above which is disabled.
2002-04-11 23:20:23 +00:00
Robert Osfield
e85e5a6ce6 Added several new methods to osg::Image to help keep track of memory and added

2002-04-11 17:15:07 +00:00
Robert Osfield
360247225e Added new osg::DrawPixels class with encapsulates glDrawPixels as and
osg::Drawable.  Added osg::Image::readPixels to osg::Image.

Made osg::LightSource to default to cullActive set to false to that LightSource
nodes don't get culled by default.
2002-04-10 21:51:34 +00:00
Robert Osfield
6f65e86057 Further work on removing Camera references from NewCullVisitor and releted

extra rather than a requirement for rendering.
2002-04-09 16:09:19 +00:00
Robert Osfield
3351306d80 Added new osg::Projection node, and osgUtil::NewCullVisitor which are work
in progress for the new support for controlling the projection matrix from
within the scene graph.

Also Added osg::State::getClippingVolume(), getProjectionMatrix() and
getModelViewMatrix() with allows drawables to access the current projection,
and model view matrices and the view frustum in local coords to the drawable.
2002-03-31 16:40:44 +00:00
Robert Osfield
56cee8c711 Move the applying of Projection and ModelView matrices into osg::State so that
it now maintains references to the last applied matrices, automatically doing
lazy state updating.  This simplifies the various places in the OSG which
were previously doing the applying, add paves the way for managing the
projection matrix within the scene graph.

Remove MemoryAdapter and mem_ptr as they arn't being used, and can potentially
confuse users by their existance.

d421e35c8d A compile fix to the new Texture subload changes. 2002-03-27 23:04:52 +00:00
Robert Osfield
33c89c3be0 Added support for setting the texture subload width and height within
osg::Texture.  The values default to 0, and in this state they are
sizes of the glTexSubImage2D are taken from the source image size.  This
allows the previous setup with no settings for subload size to work as
before.
2002-03-27 22:51:58 +00:00
Robert Osfield
84d2d01163 Added support for osg::MemoryManager which is based upon Paul Nettle's
memory manager published at flipcode.com.  This can be turned on
with the OSG_USE_MEMORY_MANGER option which then uses custom global
new and delete operators as well as provide osgNew and osgDelete macro's
which add ability to log line and file from which calls are made.

Updated osg,osgUtil,osgDB,osgText and osgPlugins/osg to use osgNew/osgDelete,
and fixed memory leaks highlighted by the new memory manager.
2002-03-26 23:52:52 +00:00
Robert Osfield
651a22453a Added osg::MemoryManger which is currently based on Paul Nettle's memory manager
published at flipcode.  I havn't adopted Paul's macro's for new/delete etc, but use
osg prefixed versions instead to allow greater flexiblity in handling include
ordering.

Have fixed a couple of new/delete[] problems which existed as a result.

To use the MemoryManager to track memory usage simply add
-DOSG_USE_MEMEORY_TRACKING to the compile line.

Have yet to move the osg from using new to osgNew, will do this next.

it more consistent with the general OSG name convetion.
2002-03-21 12:36:05 +00:00
Robert Osfield
a364875afb Added osg:State:have_applied_mode(mode) and have_applied_attribute(type) to make it
easier to specify which modes and attributes have been modified without
the user requiring to know to what value, or to have an equivilant attribute
to pass to the have_applied_attribute method.  The original have_applied(mode)
and have_applied(attribute) methods have been renamed have_applied_mode(),
have_applied_attribute() as this was required to prevent the mode and type
values colliding during compile (it was causing a compile error when the method
names were the same.)
2002-03-21 12:00:10 +00:00
Robert Osfield
9836af1055 Added osg::TextureCubeMap which encapsulates OpenGL's cube texture mapping. 2002-03-20 22:39:51 +00:00
Robert Osfield
8656adb463 Added a Referenced::unref_nodelete() method which unreferences but does
not delete the object even if its count goes to 0 or below.  This should
only be called in special circumstances, the ReaderWriter::ReadResult
being one of them. This new method has allowed the problem of objects
being multiple referenced on return from readNodeFile() & readImageFile().
2002-03-20 14:03:30 +00:00
Robert Osfield
0b27e5c381 Updates to Texture and TextureCubeMap to clean up the code so they share

c49c62ee15 Integrated various changes worked on at the Glasgow Science Center. Changes
include change the CameraManipulators so they work with double for time
instead of float.  Also added support for DataType to osg::StateAttribute
and StateSet so that they can be set to either STATIC or DYNAMIC, this
allows the optimizer to know whether that an attribute can be optimized
or not.
2002-03-14 17:34:08 +00:00
Robert Osfield
e80496d5db Changed Texture so that is use lazy updating on texture paramters (Filter/Wrap)
mode by using a _texParamtersDirty flag in combination with an
applyTexParamters(State&) method which does the paramters setting in one
tidy bundle.  This new implementations replaces the CompileFlags submitted
yesterday.

Simplified NodeCallback by remove osg::NodeCallback::Requirements as they
are no longer needed.

Fixed comments in Drawable.

Put guards around cosf definations so that they are only used under Win32/Mac.

d12a726d5b Various investigations into culling errors w.r.t matrix inversion resulted in
the conclusion that the osg::Matrix::inverse was broken, have lifted a new
implementation from sgl and it seems to work fine.  Will need further testing
but looks good.
2002-02-07 01:15:15 +00:00
Robert Osfield
ff571d2690 Added a check to the destructor of Referenced so that it detects referenced
objects that are deleted whilest still having a positive _refCount, such
as when a object has been deleted on the stack, yet other references still
exist for it.  Have put the desctructor implementation in Object.cpp to
avoid adding yet another file with only a couple of lines of code in.

a703130aa0 Have taken a few more steps towards support for view dependant transformations
by adding a ComputeTransformCallback to osg::Transform, and have now removed
the recently added AutoTransform since it is nolonger required.  Have also
updated CullVisitor to account for the new ways for tracking transformation
matrices in the scene.
2002-02-05 21:54:46 +00:00
Robert Osfield
7293af59ed Have removed the old lazy initialization of Matrix since it was causing bugs
and adding checks to many mothods which in the end slow it down more than
not intilizing the code!  The code is now simpler, more robust and faster:-)

7b370fcb57 Made the LineSegment destructor protected to force users to create segments
on the stack thus ensure that they arn't created locally and have their
memory deleted incorrectly.

Also updated the IntersectVisitor so that it no used osg::ref_ptr<> internally
for storing all data. Have also move the IntersectState helper class to inside the
IntersectVisitor which simplifies the external interface to the class.

Robert Osfield
2487861fbc Have add new osg::CopyOp which replaces last nights osg::Cloner, the new
class now combines Cloner and DeepCopy into one class. Cloner and DeepCopy
will be removed in next commit.

Also have added osgcopy app to Demos which shows how the CopyOp have be
subclassed to create users own specific handling of copying.

Have fixed copy constructor problems in GeoSet which fix the deep copy
problem experienced yesterday.

f0174e34a3 A couple of fixes to DeepCopy Cloner. 2002-01-28 21:49:31 +00:00
Robert Osfield
f612924a45 Added support for shallow and deep copy of nodes, drawables and state, via a
copy constructor which takes an optional Cloner object, and the old
osg::Object::clone() has changed so that it now requires a Cloner as paramter.
This is passed on to the copy constructor to help control the shallow vs
deep copying.  The old functionality of clone() which was clone of type has
been renamed to cloneType().

Updated all of the OSG to work with these new conventions, implemention all
the required copy constructors etc.  A couple of areas will do shallow
copies by design, a couple of other still need to be updated to do either
shallow or deep.

Neither of the shallow or deep copy operations have been tested yet, only
the old functionality of the OSG has been checked so far, such running the
viewer on various demo datasets.

Also fixed a problem in osg::Optimize::RemoveRendundentNodesVisitor which
was not checking that Group didn't have have any attached StateSet's, Callbacks
or UserData.  These checks have now been added, which fixes a bug which was
revealled by the new osgscribe demo, this related to removal of group acting
as state decorator.

06bd9fda5b Have made osg::Transform more extensible via additions of new getLocalToWorldMatrix()
and getWorldToLocalMatrix(), computeLocalToWorld() and computeWorldToLocal()
methods.

Have updated the CullVisitor, IntersectVisitor and Optimizer to use the
new osg::Transform::getLocalToWorldMatrix() which has the same functionality
as the old getMatrix() but is now supports subclasses of osg::Transform
transparently.

Have added osg::PositionAttitudeTransform as subclass of osg::Transform
which manages the transform as position and attitude via a Vec3 and Quat
respectively.

98c8447ae9 Fixed the osg::Light so that it requires the user to explicitly define which
OpenGL light is being operated on, and also now relies upong the standard
osg::State handling of OpenGL modes to switch on the appropriate lights.

The previous static counter mechansim for the light number was causing a
redundent light to be created when the osg plugin created the first osg::Light
to use a prototype for other osg::Light's to be cloned from in the
.osg plugin execution.

The static count mechanism also prevent the lights modes being controlled
independantly from the setting of the light paramters themselves.  This
meant that a light once created was global, and couldn't be turned off
locally via the OSG's support for OpenGL mode enabling/disabling.  This
has been overcome with the new implementation, the user has complete
flexiblity of when and where to use the different lights at their
disposal.
2001-12-24 21:34:40 +00:00

f848c54ba3 Made the following name changes to Matrix and Quat to clean them up and make
the functionality clear given the name.  This will break user code unfortunately
so please be away of the following mapping.

  osg::Matrix::makeTrans(..)?\026 -> osg::Matrix::makeTranslate(..)
  osg::Matrix::makeRot(..)?\026   -> osg::Matrix::makeRotate(..)
  osg::Matrix::trans(..)?\026     -> osg::Matrix::translate(..)

  osg::Quat::makeRot(..)?\026     -> osg::Quat::makeRotate(..)

Updates to the osg::Transform, adding preMult and postMult methods and
deprecating the old preRotate,preTranslate,preScale.

Updated the rest of the OSG so that it nolonger uses the deprecated
osg::Transform nodes.

Renamed osgUtil::SceneView::setGlobalState() to
osgUtil::SceneView::setGlobalStateSet() so that the name reflects its
functionality better.  Updated osgGLUT::Viewer etc to cope with new
name change.

Robert Osfield
7290f793f1 Added osgText::Paragraph which is a subclass from Geode which composes a
list of text drawables as a paragraph block, handles breaking of text into
individual lines automatically.

Changed the osg::Node::setUserData so that the data type has to be an
osg::Referenced, and removes the dependancy on osg::MemoryAdapter.  I have
done this since it simplifies the OSG side of the interface and makes it
less like that the user might abuse the memory managment of the data. It
does however mean that user data will have by subclassed from Referenced,
and therefor may require users to have their own adapter to do this.
However, this little nuasance is worth the extra cleaness and robustness
afforded by going the osg::Referenced route.

42faf78b47 Updated index.html with dependacy info about the new osgText library.
Modified osg/Drawable::draw(..) so that it uses display list COMPILE
rather than COMPILE_AND_EXECUTE to solve performance problems under
NVidia drivers.  The old behavior is still available by comments out
a #define.
Fixed the default compilation list src/osgPlugins/Makefile so that it
compiles by defalt png and gif.
2001-11-02 12:26:33 +00:00
Robert Osfield
4d4ff39ff9 Added a bool paramter to osg::StateSet::compare(const StateSet& rhs,bool compareAttributeContents=false) const;
to allow it to use different comparison schemes, now it can use checking for pointer equality (the default)
or attribute contexts.  This has been added to assist optimization of databases within the flt loader, but
also could be useful for other operations too.
2001-10-31 20:04:32 +00:00

to osg::StateSet.
2001-10-22 22:02:47 +00:00
Robert Osfield
54d490e24b Added support for specifying whether view frustum and small feature culling
should be applied to a node or its child with the new osg::Node::setCullingActive()
flag.  A mechanism has been implemented so that if child has its culling disabled
then their parents, all the way up to the root are also have their culling
implicitly disabled.

The osg::CullVisitor has updated to take account of
both the explicit control via setCullingActive and the implicit culling
disabling through children being disabled.

This feature is useful for nodes which don't have a bounding volume to cull
against, earth sky implementations and light sources.

The default osg::Node::_cullingActive is true, i.e. culling is enabled by
default.

to automatically handle the memory deletion.
2001-10-15 14:29:40 +00:00
Robert Osfield
59077fed15 Added support for automatic creation of global StateAttributes to osg::State,
these global attributes are created by cloning any attributes which are
applied during rendering, the clone in a shallow copy, which will set up
default valus for that attribute.  This should prevent attribute bleed
from one stateset to the next when the global StateSet doesn't contain
an attribute used within the scene graph.
2001-10-15 14:07:54 +00:00
Robert Osfield

1e4a0cadf5 Changed the naming and calling convention of the new Drawable::AttributeFunctor
and have updated GeoSet to use mutable values for the _numverts etc, allowing
osg::GeoSet::computeNumVerts() to be a const operation. osg::GeoSet::getNumVerts
is now a const once more, so avoiding compilation problems.  Also chaned the new
osgconv orientation code to use a Drawable::AttributeFunctor so it can work on
other Drawables other than just GeoSets.
2001-10-13 11:16:10 +00:00
