This demo is showing off a few of the new features from 1.5:
1. The new RectangleTriangleCuller
2. The new InteractiveScene3D scene with an InteractiveBitmapMaterial – click/mouse over the rings to see the highlights
This model is from the Obstacle Course game and is 4106 poly’s total. With the latest rev, I can rotate all that geometry and still make it interactive without taking a hit in performance.
