... > >> performance ? change graph structure, culling ???? i would have thought my normal display resolution here is around 1900 * 1200 pixel. which means that if your 8.5 million pixels only 1/4th get rendered in the final image, and only if each vector is represented by a single colored pixel. which means: to get really great fps one should think about a different way to render those 8.5mio vectors to the screen, eg. to render only a subset (LODs comes to mind, carmack's megatexture approach is interesting as well) > >> performance ? change graph structure, culling ???? i would have thought > >> that the performance would improve as you spread the geometries over a > >> number of nodes ? if all the vectors getting to the render-tree then having more overhead (more scenegraph nodes) basically just is .. overhead :) > That is a core question.
