Controlling the Level of Detail with Progressive Meshes
There are cases where you'd only want to simplify a mesh (for example, imagine a model for a rocket you've fired). However, if you are only simplifying, it means the object's detail never needs to be increased, which isn't as common as the cases where you may need to progressively lower or raise the level of detail. I'm sure you can see where the name of the progressive mesh came from.
To show the behavior of the progressive meshes, we will write a similar application to the one we wrote for the simplification mesh a moment ago. However, instead of just simplifying, we will also allow you to raise the level of detail by bringing the model closer to the camera as well. Once again we will ...
