12226e4371 Converted the instances of const built in types being returned from methods 
and passed as paramters into straight forward non const built in types,
i.e. const bool foogbar(const int) becomes bool foobar(int).

8353fc0ed6 Removed deprecated code from the distribution. 
Added .osg support for Texture1D and Texture3D.
 2002-08-28 15:28:11 +00:00
Robert Osfield
7d6197441e Added Neil Salter's osgUtx library into the distribution, have put all the 
orignal seperate headers and source into include/osg/UnitTestFrameWork
and src/osg/UnitTestFramework.cpp respectively.  I have done this to
keep the include and source directories focused on the scene graph rather
than the test framework.

Have added a very simple unit test to Vec3.cpp, which are optionally
compiled in with the OSG_COMPILE_UNIT_TESTS define, which is only
currently defined in debug builds under unix.  It should be fine to
add it in under Windows project files as well.

Finally, a new demo app osgunittests runs the tests and reports success
or failure of the tests.

bff4728eac Commented out the #define TEXTURE_USE_DEPRECATED_API from includ/osg/Texture 
which forces the use of a typedef Texture2D Texture; in place of the orignal
texure implementation.
 2002-08-27 21:01:22 +00:00
Robert Osfield
55d4affded Added support for DOFTransforms into .osg format, and add pivot point support

103727f412 From Marco, fix to include/GL to clean up warnigns in Windows builds. 2002-08-27 14:00:04 +00:00
Robert Osfield
83af5e7a95 Added osgtexture3D demo, renamed osgtexture demo to osgtexture2D, and have 
added osgtexture1D demo which currently is simply copy of osgtexture2D. I
will be modifying it to do 1D texturing next.

Fixed a bug in osg::Texture3D relating to checking of existance of
texturing.

Merged some fixes to the pfb loader from Ulrich Hertlein.

Robert Osfield
239068f223 Added new osg::TextureBase, osg::Texture1D, osg::Texture2D, and osg::Texture3D 
classes, and changed osg::Texture and osg::TextureCubeMap so that they now derive
from osg::TextureBase.

 2002-08-22 09:19:41 +00:00
Robert Osfield
ed3d083368 Fixed the osg::Transform::coompute*() methods so the were using the _referenceFrame 
correctly, as previously they were doing the exact opposite from what they
should have been doing.
 2002-08-22 08:14:38 +00:00
Robert Osfield
c2c6bb5ca6 Moved the include<osg/GLExtensions> from the State header into State.cpp, and 
added it into other files which now required it.
 2002-08-20 22:43:42 +00:00

Added #include<string> to the GLExtensions header.
 2002-08-20 12:29:35 +00:00
Robert Osfield
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.
 2002-08-20 10:14:12 +00:00
Robert Osfield
93303cf1cd A FogCoordinateSource set/get methods to osg::Fog which correspond to the 
FogCoord support added to osg::Geometry. Added suppot for these new parameters
to the .osg plugin.
 2002-08-20 10:08:04 +00:00
Robert Osfield
7a0f041a15 Added default values to the TexEnvCombine constructor. 2002-08-19 19:53:34 +00:00

Robert Osfield
b23a48a763 Renamed the osg::EarthSky to osg::ClearNode to make it more obvious what 
role it has play and make it more relevant to non vis-sim applications.
 2002-08-19 11:42:37 +00:00
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.

2c174237c7 Fixed typo in #define of UBYTE4 2002-08-17 07:34:11 +00:00
Robert Osfield
2ab0f689eb Added Texuture::SubloadCallback example into the osgprerender demo to illustrate 
how to use it.

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 
and osg::Image.  This additions are design to make texture subloading more
flexible.
 2002-08-16 13:33:32 +00:00
Robert Osfield

Robert Osfield
743b174da9 Added new s/getPivotPoint() support to osg::PositionAttitudeTransform. 
Modified the osglight demo to use an AppCallback and a PositionAttitudeTransform
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.
 2002-08-11 21:26:58 +00:00

392150521a Fixed the X and Y axis rotation billboards so that now rotate correctly. 
Rewrote the osgbillboard demo so that it creates a point rotatated billbaord
and X,Y and Z axis billboards to both test and demonstrate this types of
billboards in action.

ed30834757 Fixed typos, sent in by Warren Macchi. 2002-08-08 13:45:16 +00:00
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
Robert Osfield
e01f9eb891 Added shells for DOFTransform and PositionAttitudeTransform to the .osg 
loader, still need to fill in the saving and loading of paramters.

Went through the distribution remove old API usage.

25740b5c7f Added new osg::DOFTransform node from Sasa Bistrovic, designed to mirror 
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.

067c10b49c Fixed comments. 2002-08-03 16:48:36 +00:00
Robert Osfield
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.

Robert Osfield
a1c54dc663 Removed the rendundent variables in the ConvexPlanerPolygon as these were 
unused and unitialized.

4594907832 Small bug fix to osg::BoundingBox::expandBy(x,y,z). 
Updated ChangeLog and NEWS for the release.
 2002-07-19 15:49:43 +00:00
Robert Osfield
7682e32521 Updates to the Geometry to add more access methods, and updates to Optimizer 
to add the new merge primtives option.
 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
share the same state and bindings.
 2002-07-18 00:53:03 +00:00
Robert Osfield

Robert Osfield
7cf7d8fadb Added protected destrcutor to TemplateArray. 2002-07-16 10:16:34 +00:00
Robert Osfield
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.
 2002-07-13 20:31:30 +00:00
Robert Osfield
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.
 2002-07-12 14:25:10 +00:00

demo which adds as spherical environment map using texture 1 to any model.
 2002-07-11 16:12:24 +00:00
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
4372c9a334 changed unsigned int/short/char* references to GLuint,GLushort,GLubyte respectively. 2002-07-11 08:28:09 +00:00
Robert Osfield
5d18f0ee11 Tidied up the types in osg::GeoSet so that the index pointers use GLushort 
and GLuint to get round compile issues under MacOSX.
 2002-07-10 22:33:08 +00:00

3700e7e2cd Reimplemted the osgUtil::SceneView::setCalcNearFar() functionality to bring 
it inline with the CullStack/CullVisitor implementation.  Also added the
setSmallFeatureCullingPixelSize() method and wired them up inside
SceneView.cpp so they set the corresponding CullVisitor paramters.

Intergrated pfImage copying change in the Performer plugin, submission sent in by Ulrich Hertlein

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.

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.
