Hello Ulrich,
An infinite plane is a little hungry on resources ;-)
I was considering contributing a working osg::InfinitePlane drawable
for a little while now... It's a useful primitive to have in many
cases. The way I would have implemented it is to create a few polygons
which are bounded by the view frustum (therefore it is not really
infinite, but as infinite as needed :-) .
The difficulty would be translating texture coordinates as the view
frustum moves, so that the textures on the plane don't look like
they're moving with the viewpoint. But even that isn't very hard I
would think.
I haven't actually gotten around to doing that. Maybe in the near
future, as I'm working on a raytracer integrated into OSG, and the
infinite plane is a classic primitive in raytracing.
J-S
