Raytracer anyone?


Recommended Posts

Developers have their Christmas also:

And one more related discovery: http://ispc.github.com/ - open source "kind of" Intel's answer to SESI's VM library, i.e. SIMD compiler for custom C-like language.

Nice to see how Intel tries to follow others in building software culture.

Yay! It builds so easily-- but I must say I'm not terribly sure it's much faster than Mantra at the end of the day. It takes a while to converge on simple scene geometry. It might be faster than Mantra for simple scenes and for getting a very snappy feeling response in this little viewer applet, but it's hard to tell how it'll scale.

It's definitely slower, but just to be clear what you're dealing with, they state this is not a renderer, but heavily SIMD accelerated structure for performing ray intersections. The engine that they have provided is only for a reference how to use Embree and does pretty crude path tracing.

When it comes to building octree with SIMD (also AVX) instructions or do tracing with ray buckets it seems to be doing very well.

Personally I've seen in Embree pretty helpful tool for building new tracing architecture in VEX in Sop/Pops. Deformers, collisions and such... HDK own stuff is quite disappointing (clearly no one has bothered SESI for updating GU_RayIntersect).
