it's been a long time since the last update, but my neurons were quite busy with Avatar, so programming at home was out of the question. Anyway, I'm back again with something different. Some weeks ago I read that someone had found a nice way to use the famous z->z^n+c formula in 3D to render something like the classic Mandelbrot fractal in three dimensions, you can find more info here: Mandelbulb . So I decided to give it a shot with the gpu and this is what I have, this time with n=8.
Remember that this is not a 3D Texture, or a polygon mesh so it's not the fastest thing in the world, basically for two reasons, my graphic card is not so great and I didn't use a Distance Estimator, so it's pure raymarching and iterating the mandelbrot function every step. Even with that limitations, it runs at interactive rates. I'll work to improve the framerate. Hope you like it!
