Hi,
Does anyone know how to access the rgba texture values at the point of
intersection in a polygon found using osgUtil::IntersectionVisitor and
osgUtil::LineSegmentIntersector? Ideally I would pass a threshold to the
IntersectionVisitor so that it automatically skips intersecting polygons
Hi Dat,
Finding specific children in a loaded scene graph is very common thing
to do, and one usually just write a custom NodeVisitor to do it. Have
a look at the osgplanets and osgsimiulation examples for an example of
FindNamedNodeVisitor - use this as a template and modify to
specialize it

Hi Wyatt,
The main idea of osgPPU is to use input textures to process them. This can be
used for rendering as also for GPGPU.
Take a look into HDR and Video examples. In the first one the input color
buffer of the camera is used to apply HDR tone mapping and glow effect and then
render it
Hi Tian,
Try using the version in the trunk, there was a header conflict with
