User controlled creation of Progressive Meshes - Cow Sequence

Here you see some reduction steps of the cow model. I've placed the reduced model in the front and the original model in the back of the scene. On the left you see the results of a fully automatic reduction, while on the right you see the results of a user controlled reduction. The user has marked the eye and the nose of the cow as beeing of higher importance. (Click the images to view at higher resolution)
