The more complex your objects are, the more triangles need to be drawn. It's been said before that you should always try to keep the triangle count as low as possible. When modeling with external tools, it's better to make a very low poly model first and then add more polygons or triangles afterwards if necessary. Doing it vice versa, by removing triangles from an advanced model, will be a lot more work.
But there are more techniques available to optimize objects. We will have a look at these in the following sections.
It sounds easy: Just remove your objects when you know they won't be visible. This does not refer to objects that are positioned outside the camera's view frustum or back facing surfaces of 3D objects, as Papervision3D will detect these automatically for us. The title of this section refers to objects that are located in the view frustum, but are positioned behind other objects from certain points of view.
Because...
