d763a47d2e Mods to MemoryManager to make the optimized build produce dummy
implementations for all the public functions found in the header,
this should prevent problems when not compiling in the MemoryManager
under IRIX 64 build.

4f4f68e961 Added support for reading the new OSG_MAX_TEXTURE_SIZE environmental variable
inside the osg::Image::ensureValidSizeForTexturing() method. The
smallest of GL_MAX_TEXTURE_SIZE and OSG_MAX_TEXTURE_SIZE is used for the
final max texture size.

This new env. var. allows users to deliberate cap the size of their textures
so they can test whether their models are limited by texture memory.  If
reducing the max texture size increases performance then you are limited
by texture memory!

b12e36cede Added computation of the bounding volume of osg::OccluderNodes.
Added support for osg::BoundingSphere::expandBy*(osg::BoundingBox) and have
added osg::BoundingSphere/Box::valid() which deprecates isValid(), this
is to be more consistent with other classes in the OSG.

b3c26d5634 Changed the osg::LightSource so its Light attribute is now generalised to
be a StateAttribute.  This allows alternative implementations of Lights
other than the standard osg::Light.
2002-06-19 08:34:19 +00:00
Robert Osfield
5e85cd59ab Added support for occluders occluding other occluders, which helps reduce
the number of occluder that will be used in cull traversal to only the
ones that will be effective. Note. Holes in occluders arn't handled in
this occluder occlusion test, will implement this later.

247cb3ff7e Checked in Macro Jez's additions to osgText to support .osg IO make it
a fully functioning NodeKit.

Also reimplement notify() to try an prevent a crash which has been caused by
to objects in notify.cpp being initiliazed twice, the second time the auto_ptr
holding the dev/null ofstream was being initilized to 0.

Robert Osfield
b2e6279178 Removed the use of __FUNCTION__ from MemoryManager to remove problems with
VisualStudio .NET compile.

Added support for OSG_NOTIFY_LEVEL and OSG_FILE_PATH into the relevant getenv
routines.  This compliments the exisiting OSGNOTIFYLEVEL & OSGFILEPATH which
are deprecated but still supported.  The OSG_ version are more consistent
with the rest of the env variables used in the OSG.

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.

e3958790a2 Changed the implementation of osg::Quat::makeRotate(heading,pitch,roll) so that
it conforms to the OpenFlight convention of euler angles.  Added documentation
into Matrix and Quat to reflect this.

Added so test code to osgcube for stress testing memory allocation and deallocation.

Commented out the registering of app and cull callbacks in osghud.
2002-04-19 19:55:48 +00:00
Robert Osfield
e17261c45f Changed the osg::Billboard comution so that it get passed in the current
modelview matrix rathan than an identity matrix, this matrix is then modified
locally.

Changed the osg::Matrix set methods so they are inline.

Added a few useful comments to MemoryManager.cpp to help people understand
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.

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.

c43607c14d Added support for specificing the eye mapping and seperation between the
horizontal and veritical split stereo modes.

Renamed osg::Image::ensureDimensionArePowerOfTwo() to osg::Image::ensureValidSizeForTexturing().
2002-04-14 22:21:59 +00:00
Robert Osfield
22e8047869 Used a faster method for checking for power of 2 on the image dimensions and
did a check on forcing 16bits textures in osg::Texture (which speeds things
up on the Umea model which is performance bound by texture memory.), the
later check is now commented out.
2002-04-14 20:30:43 +00:00
Robert Osfield
09d41789da Fixes to osg::Image::createImage(..), and addition of code to Viewer.cpp to support
output of screen snapshot via 'O'.

Robert Osfield
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.

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
osg::Image::readPixels to encapsulate glReadPixels.

Added some defines to Image in prep for writing code to determine how big a
pixel is.
2002-04-10 22:10:07 +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
classes, this work paves the way for making osg::Camera an optional
extra rather than a requirement for rendering.

aa0e398cf7 Fixed a small oversight in the previous bug fix. in GeoSet::computeBound()
_numcoords is NOT necesarily _cindex._size.
2002-04-05 02:49:58 +00:00
Don BURNS
1de448df4a Fixed a small bug in compute bound that caused it to come up with the
wrong number if the coord array was indexed, and containing bogus
(unindexed, yet in-line) numbers.
2002-04-04 00:30:10 +00:00
Don BURNS
e0adca775b Reinstated Norman Vine's TARGET_BASENAME variable in the makefiles and
added prefixes and suffixes to libs and plugins.  ALl this to accomodate
cygwin...

Also added INST_SYS_PREFIX and INST_SHARE_PREFIX for installation, as well
as "standardizing" the install locations for the various platforms.
2002-04-03 17:42:12 +00:00
Don BURNS
3e6638320a The new order for building OSG. All Makefiles are replaced and
the Make directory is left with four files only :
    makedefs
    makerules
    makedirrules
    instrules

These work for all platforms supported so far, which include :
    Linux
    Irix
    Solaris
    MacOSX
    Cygwin
    FreeBSD
2002-04-02 06:44:57 +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.

434d7b98e5 Fix for Cygwin build. 2002-03-30 15:13:33 +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.
2002-03-29 17:26:40 +00:00

34c05db393 Fixes for IRIX build. 2002-03-28 23:06:20 +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.

77ae5ddcb6 Updates to various files, replacing delete calls with osgDelete so that
greater debugging info can be gleaned.
2002-03-27 14:56:47 +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.

03cda7d3f8 Renamed have_applied_mode, have_applied_attribute, apply_mode, apply_attribute
to haveAppliedMode, haveAppliedAttribute, applyMode, applyAttribute to make
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
0b27e5c381 Updates to Texture and TextureCubeMap to clean up the code so they share
much more of the core texture setup code. This largely invloved paramterizing
the applyImmediateMode, which has also been rename applyTexImage to reflect
its functionality better.
2002-03-20 11:24:47 +00:00

Robert Osfield
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.

d0ee300405 Fixed DrawCallback in Drawable and added CullCallback to Drawable
Cull Visitor now checks for a Drawable's CullCallback and calls it
if it exists.  It then prunes based on the return value (bool) of the
cull callback.

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.

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

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.
2002-01-29 12:52:04 +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.

9a59cf0fe2 Changed the ordering of applying OpenGL modes and attributes back to the original
modes first then attributes since the it was cause a display bug on some
datesets.  It seems that the modes needs enabling before glMaterial's
take affect, at least on the NVidia drivers under Windows and Linux.
The OpenGL reference guide doesn't mention any dependancy so I'm not
sure what the official line is.  Some other OpenGl attribute and modes
need to be applied in that order according to the blue book, however,
drivers, at least the NVidia drivers seem require the opposite.  This may raise
the spectra of before and after mode applies, but this will require extra
support in osg::State and osg::StateAttribute, and would have to be handled
on a per attribute basis, and possibly different of each platform.  Yuck.
