Hi OSGers, I have to display a high number (>500) of similar cylinders: - Same size (both radius and height) - Same texture coordinates (but different texture) - Different positions, but fixed (the cylinders don’t
move) - Each one has to be a different drawable (or node),
so that they can be individually picked, change color or texture. I’ve used osg::Cylinder until now, but due to
its texture coordinates autogeneration, I have to change to, probably, geometry. Which is the most efficient way? Assigning each
geometry a unique texcoord array saves opengl calls or just main memory? A
MatrixTransform above each node, sharing vertices between geometry or computed
vertex positions for each geometry? Thanks for your suggestions. Ignacio Garcia |
