Elite Force Raytracing Demo

Early demo of a raytracing version of Raven Software's Star Trek Voyager: Elite Force. Running on a single AMD Athlon X2 3800+ at a resolution of 426x350 pixels. Single light source (camera) and no shadows yet.
Full support for Quake 3 world architecture (Bézier curves, md3 models) and surface shaders.

looks good!

[OnionMad]

no, it's actually the CPU in these old demos.

because it's MUCH easier to program a code that's executable through the SSE2/4 (cpu) than the shader-processors in the gpu. also, this wouldn't have been possible untill the launch of DX10, witch included unified shaders wich makes the developers able to execute pretty much anything through the SP's

@msqrt yafray is a nice raytracer.

[Dth091]

@msqrt slow as hell because there are no GPUs that are specifically designed for it. GPUs nowadays mainly do rasterisation, but raytracing can be done in parallel to that so you could make a GPU that has the capabilities for both.

@PPKproductions3 Well, most offline 3D renderers (renderman, vray, mental ray, the ones that come with modeling software) are ray tracers. Or you can write your own, which is somewhat challenging but fun.

@msqrt So what tool do you use to raytrace then?

[msqrt]

@Genesis6100 Lots of math. Basically cast a ray for every pixel on screen, calculate where it's going and where it hits surfaces. Take the nearest hit, that's your object. Now you can go on and calculate texture coordinates and cast rays to lights to see if the surface is lit and how brightly (if the primary hit to light ray is occluded, it's not litten, otherwise normal lighting stuff)

Good for reflections, refractions and stuff, can render infinitely smooth objects, slow as hell. Usually.

How do you raytrace?

[DEFECTX9]

@FOGoticus Taci, tu non sai un cazzo

[FOGoticus]

@DEFECTX9 Lol.... you really have to study dude.

Advanced ray tracing just makes shiny things look real.

Tessellation just takes the normal map and turns it into a model.

Can't you just get it those 2 have almost nothing in common?

[DEFECTX9]

@FOGoticus Yes Tessellation is Advanced Ray tracing

[FOGoticus]

@DEFECTX9 nope.... you added tessellation here for no reason.... I mean, just adding ray tracing here and tesselation would look awesome. It's just usless.

And no. They will not disable ray tracing or advanced ray tracing for tessellation.
