Irrlicht Engine

very nicely done 0.8 Niko. Cool efects. Good job. I don't yet testet the new engine because i made some changes in the old one and i need to modify the new version and to recompile it. I belive the particle bug is fixed :D and now we have bowth types of particle. Also I send you some code about the ...

added optimization.h for: abs ... i use in game fast distance(2d) sqrt sqrtfast, sqrtfa (one version for floats and one for double) ... and change all the sqrt, and sqrtf in the engine with something like that or an other code .. asambly .. etc (sqrt, sqrtf, abs ... are very slow) for the code for s...

the function isCulled is performing culling with cam->getViewFrustrum()->boundingBox the real frustrum isn't a box. because i use an very big FarValue (the game is in space ... any way there are optimizations... 4 me) , there are many meshes send to the video card what are not rendered ... If a game...
