Intertactive 3D Cube with Dynamic Textures

Intro

We are moving along with assignment 2 of chapter 2 of Professional Papervisoin3D. And in the first video below you learned how to build the standard Papervision3D class presented  in Chapter 2. And in the next three videos you learned how to use BasicView to build an interactive cube with dynamic textures. Dynamic means that you can change the textures while the program is running just by clicking on them.
