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!

77e1fb7f80 Added support for reading and writing OccluderNode's to the .osg file format. 2002-06-19 16:06:03 +00:00

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.

d3b4a36447 Added the length argument to a std::string argument, under Linux it
compiled with the default value npos, under Windows it broke the build,
add the npost excpilicity should get round this difference in implementation.

6767dd49d0 Rewrote the FileUtils support for data and library file paths, moving the
storage of the path lists into osgDB::Registry, and changed the data
structor from a char* to a std::deque.  Changed a names of couple of the
convinience functions in osgDB/FileUtils to better reflect the two
public FilePathList's - DataFilePathList and the LibraryFilePathList.

Added support into the osgDB::Registry::readNode/Image/Object methods
for pushing and popping the path of the current file being loaded.

52c36dde70 Added computation of occluders volume scaled relative to the frustum volume,
all volumes computed in eye coords.

7adb75c572 Added occluder hole test code into the osgoccluder demo. The code works,
but I've commented it out right now as the Geode physically representing
the occluder doesn't yet have a hole in it - just a cosmetic thing.

73ec80843f Refined the CollectOccluderVisitor so that it checks the subgraph below
a node contains occluders before traversing.

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

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.

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.

d91b848a63 Checked in migration from osgUtil based GUIAdapter code to Neil Salter's
osgGA (Gui Abstraction).  This may break users code, but all it should
require to fix the builds should be a change from
osgUtil::CameraManipulator (etc) to osgGA::CameraManipulator and
include <osgUtil/CameraManipulator (etc) to osgGA/CameraManipulator and
the extra dependency of the link line.

0a8d0a255f More more occlusion culling. 2002-06-08 19:58:05 +00:00
Robert Osfield
bf6bf60e21 Added osgoccluder demo, it creates a single quad occluder, but the culling
code is not complete yet, so it won't actually do any occlusion culling,
the demo is here so I can test the evolving occlusion culling code.
