Yesterday I helped my friend Tudor with a problem. When we solved it he got excited and told me to blog about it. Whatever Tudor says has to be done so here we go :-).
He was using the Ribbon3D class which is based on Papervision3D. Instead of using a color material he wanted to use [...]

This post is all about UV coordinates and how to use them in Sandy 3.0, although the theory applies to other engines like Papervision3D too. There’s a little bit of theory involved and some hands-on coding.
About UV coordinates
In simple words: UV coordinates are 2D coordinates that are mapped onto a 3D model. UV coordinates [...]

Did Flash 3D engines like Sandy, Papervision3D and Away3D get you interested in 3D? Do you want to know a little more about the stuff that’s happening inside? Then the following documents will interest you. They’ll tell you a little about topics such as:

vanishing point
3D to 2D projection
translation
rotation
perspective correction
bresenham algorithm
interpolation
optimization
perfect 3D mapping

All in all a [...]
