Crytek's MassLighting early implementation
|
Hi,
This is an early implementation of Crytek's Mass Lighting in my personal engine.
I use 2d textures of size (nbrCellX , nbrCellsY*nbrCellsZ) instead of CryEngine3's 3d textures, to not require copying the ML rendering target to the 3d texture... |

Quice nice. But your metaball is really slow, it updates at maybe 5Hz on my Core2Quad Q9450.
My GPU-only implementation is quite faster - it runs in real time on consoles ;)

Quote:Original post by arkangel2803Sorry by my ignorance but, writing color pixel in a volume texture per every light of massive light system is not a slow method ? I dont know at all but if Crytek uses it, then it will be fast.

Correction: You *are* doing what Crytek is-- they explain that they use a regular 2D texture and some old-fashioned hackery instead of the volume texture approach for their reference implementation :)Yes, I've r... |

Arf nice! I plan to implement this also!!! :D
Are you using spherical harmonics for now?
Hi/Salut,
in the above screenshots no. I've implemented them yesterday's evening (ML with 1024 lights, using spherical harmonic... |

Doh! These previous shots were made with a debug build.
A release build keeps hitting my vsynch with 1024 lights:

Which one of the different models are you using? The .3ds one?
Yes, the 3DS one. |

Looks good!
One question though, how do you handle texture filtering?
The good thing about the 3d texture is that you have automatic filtering between all three dimensions, do you take multiple samples or is... |
