Granyte and cie

I added quite a lot of new stuff to my planet renderer first i moved the noise algorythm from the cpu to the gpu the algorythm is still slow but it allow for the generation of 6 height map of 2048*2048 in less time then it took the cpu to generate a single 512*512 map i also completed the implementation of the atmospheric scatering the parameter are a little unbalanced but i though it looked cool I also integrated physic accurate with the mesh using bullet physics here is a short video Sadly i had to disable the physic as bullet does not play wel with shape shifting mesh.

After generating the mesh i started to integrate my perlin height map generator and my terrain splating shader the atmosphere on the last one could look beter but i mesed with the constant and was a little to tired to fix it the three last pictures are all taking that same mountain at diferent distance

This is my first atempt at a lod system using irrlicht renderer currently i'm using a single octave of perlin noise generated on the fly to build the variation on the surface of my mesh

On my Quest to learn HLSL Shader programing i stubeled upon a blog where some one built an implementation of John Conway's game of life using compute shaders after looking up the rules i though about tryingto build one using pixel shader. here is the result running 1024*1024 at 449 iteration per seconds( i might even be able to get a few more out of it) in my edition the dead cells leave a corps behind that slowly fade the color tel wich rule killed them. it runs on pixel shader 2.0 directx 9 while my hardware run shader model 4.1 i generaly build for the lowest possible hardware. randoom cells can spawn from just about any type of image but if you wanna try to manualy build a cell you will need to edit a file pixel per pixel and the file will need to be exactly 1024*1024 So here is the download link  http://www.mediafire.com/?t2ze5jw9q82szcg this version currently require that you install microsoft visual C++ redistribuable here are the links for the downl...

here comes atmospheric scattering this implementation is based on Sean O'Neil openGL implementation wich has been ported to directx for ogre by HexiDave . The original converted implementation was vertex shader based for mie and rayleight color calculation and mixed them in pixel shader to try to obtain a smooth result this made sens when Sean O'Neil implemented it on the merly begning graphic hardware but it gave horrible artifact unless you have a over tesselated sphere irrlicht's 256 polygon sphere were just not cutting it. So i updated the code to make all the calcultations in pixel shader giving a much smoother result independent of the poly count of the sphere.   And for the sake of it a nice sunrise at 1920x1080 (i can't take screen shot in full screen -.-) I just need to verify the license and i will release the completed shader code with constant what is messing and why you most likely are not getting it to work in case you stumbled on my ...
