Hi, this is rather a technique question then related to an osg feature. I create a VBO from lot of Points ( ( 50-100 ) ^ 3 ) in the shape of a cube. I create them with three nested loops, one per Axis, so that first I get a line of Points in x-Direction, then draw the next lines to shape the xy plane, and finally draw the volume in z direction with the next xy point planes.Rotating arround this cube with the camera, my Frame Rate drops significantly, when the Points get drawn from Back to front due to Overdraw. I can't just flip the whole entity in 90 degree steps dependent on the camera position as the Points have different Vertex Colors set, so one would nottice the flipping.
How can I build an efficient structure so that those points get always drawn from Front to Back ? Are there any helpful utilities for sorting, or maybe other Tricks ? Thank you!
