SLG

From LuxRender Wiki

SmallLuxGPU is a demo and proof of concept, functioning is as a testbed for LuxRender development. The program is now included in LuxRays, which is being integrated in LuxRender 0.8. More technically speaking, is a hybrid CPU+GPU path tracer based on a data parallel model (i.e. thousands of paths are traced at the same time). CPU support is done via native threads while GPU is done via OpenCL. For more background information, see SLG History). For OpenCL benching there is a tool Called LuxMark that also uses SLG, for a little preview it is recommended to use this.

Right now SLG offers 4 different rendering algorithms. Like LuxRender, it is a physically based renderer.

As the program is experimental and was never intended to be a finished product you may run into problems in the beginning, in that case please refer to the forum and this Wiki.

SmallLuxGPU is for people that...

• want to use their GPU for rendering (not just for gaming)
• want to have fast raytracing
• are technically minded
• can solve middle technical problems
• want to use freeware and/or like the concept of Open Source software
• maybe want to program themselves(especially OpenCL)
• like making use of OpenCL
