Swirl!

[SAB]

Here's a program I wrote.
A Friend help me with the concept.

Damn, this one won't run either

It was kinda slow here.

I have a faster version that looks the same has SAB's but I won't hijack his post, :*)

Actually this effect is one I always wanted to do. Maybe it's not that hard now I have got used to polar coordinates in my other effects. I even dream to do this one on the 8bit CPC computers, there it will be a world first cause nobody have tried before! On the C64 I have seen it a lot of times. On the accelerated side, you need a grid I guess? Maybe the grid is having too many vertices. I'll check the code and try to reduce the grid res in order to see it faster. Though it might be not that preety with low polygon grids. Pure soft pixels rulez!!!

rel: Have I seen that version in a demo of yours? I can't remember. I'd like to check it again if so

I don't think I've released my OpenGL swirl thingy.  It uses the same trick I used here though...
