part of prep for supporting both Matrixf (float) and Matrixd (double).
Added osg::Matrixf::glLoadMatrix() and osg::Matrixf::glMultiMatrix() methods
and changed corresponding usage of glLoad/MultMatrixf() calls across to use these
methods. Again prep for support Matrixd.
Fixes for VisualStudio 6.0 compile.
made ENABLE_ALL_CULLING enable all culling including the near and far plane.
DEFAULT_CULLING is now used for the default as uses the same original
values as ENABLE_ALL_CULLING once did - view frustum culling with near and
far culling. SceneView now uses DEFAULT_CULLING.
osgProducer::Viewer. Removed methods in PickVisitor which wern't being
used by osgProducer::Viewer. This has been done because the PickVisitor
interface and implementation weren't ready for general usage.
/** compute, from normalized mouse coords, for sepecified Camera, the pixel coords relative to that Camera's RenderSurface.*/
bool computePixelCoords(float x,float y,unsigned int cameraNum,float& pixel_x,float& pixel_y);
/** compute, from normalized mouse coords, for sepecified Camera, the near and far points in worlds coords.*/
bool computeNearFar(float x,float y,unsigned int cameraNum,osg::Vec3& near, osg::Vec3& far);
/** compute, from normalized mouse coords, for sepecified Camera, intersections with the scene.*/
bool computeIntersections(float x,float y,unsigned int cameraNum,osgUtil::IntersectVisitor::HitList& hits);
/** compute, from normalized mouse coords, for all Cameras, intersections with the scene.*/
bool computeIntersections(float x,float y,osgUtil::IntersectVisitor::HitList& hits);
inheritence to allow handler to also be used as node callbacks.
Fix to UpdateVisitor to make the visitation of Drawable more consistent
with the way that nodes are traversed.
2) Changed Makedepend system to make individual dependency files, which
should save time rebuilding dependencies by limiting the regeneration
of dependency file for only modified source files.
by osgUtil::RenderLeaf to test if any abort state has been set, if so it
doesn't do any further drawing.
The osgProducer::Viewer has been set up to set the osg::State's it manages
with their AbortRendering flag pointers set to the osgProducer::Viewer::_done
memeber varaible. Now when escape is pressed the rendering is aborted early.
