Mesh decimation in flash

I’ve implemented “new QEM” algorithm ( http://research.microsoft.com/en-us/um/people/hoppe/newqem.pdf ) for mesh decimation, or other words – for simplifying meshes.

It supports appearance attributes, but when texture has many discontinuities – my decimator generates errors and your model can be jagged/distorted.

I’ve made a little web interface to allow you some testing.

You can download your decimated model and do whatever the hell you want with it.

I’ve also created a model viewer. I had to make custom pv3d camera control, because papervision3d’s Camera class has million bugs ( with rotations for example ). There are some bugs in environment mapping too, but I didn’t have time to fix them …

Here’s my mesh decimator with some trial models: http://exp.teleranek.org/teleqem/Converter.php?showfiles
