Collision Object

collision_object.jpg Collision objects don't have an impact within the SpeedTree Modeler, but they can be queried through the SpeedTree SDK for use in real-time. Collision objects are used for detecting collisions with players, projectiles, vehicles, etc. They can be used alone, or perhaps as a fast method for identifying collisions before something more exact is used, like per-polygon tests.
