49ab8f4706 Added new osggeometry demo to test the work on the new osg::Geometry Drawable. 2002-06-21 16:45:45 +00:00
Robert Osfield
476f931eaa Addd new experimental osg::Geometry Drawable which will eventually replace 
GeoSet.  Currently doesn't draw anything, and is very much in the
early design stages.

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.

21beb236d2 Added support for occlusion of holes in occluders, and cleaned up the 
interface to ShadowVolumeOccluders.

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.

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 node contains occluders before traversing.

fa13d948b5 A little more work on Occlusion culling. 2002-06-11 19:52:55 +00:00
Robert Osfield
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.

e1ba8a6292 Added osg::CollectOccludersVisitor which is a helper class for finding active 
occluder in the view frustum, to be used as pre cull traversal.
 2002-06-10 13:50:25 +00:00
Robert Osfield
348419219d Created new helper class osg::CullStack to handle the accumulation of projection, 
modelview and culling sets, to be used during travesal of the scene graph, such
as the cull traversal.

5feba17410 Added new osg::OccluderNode which subclasses from osg::Group, and will

84dd24ce3f Fix for MacOSX build, making sure that the compresed tex image is defined 
on all builds by removing the #ifdef's but then changing the name used
in the typedef so it doesn't collide with local implementations.

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.

dcfef4a023 Integrated submission from Boris Bralo: 
Supported added for precompiled mip maps stored in osg::Image, and read

precompiled mip maps.

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.
