Modeling is a very broad topic as there are many 3D programs, each with numerous features. When you want to display custom objects besides the built-in primitives, you can load models created by 3D programs.
This chapter showed how to create basic models in 3ds Max, SketchUp, and Blender, and how to export them for Papervision3D. To do this we've used three different file formats:
COLLADA (.dae): An open source 3D model file type, which has been supported since the early releases of Papervision3D. This is the most developed file type, which also supports animation and animation clips.
3D Studio (.3ds): An established 3D file format that is supported by most 3D modeling programs.
SketchUp (.kmz): A format that is used by Google Earth, which can be created by a free program called SketchUp.
Creating models for use in Papervision3D has some requirements and conventions to take into account:
Keep a low polygon count
Add polygons to problematic parts of your model to prevent z-sorting artifacts...
