CulDeVu vs Global Illumination

CulDeVu

1718 views

Hellooo there!

Final exams are a humbling experience. During them, professors manage to hone in on every moment you ever felt stupid or unable to grasp a concept, and then make you relive it with a frightening 40% weighting. I'm particularly terrified of my university physics course, which is ironic, considering I've spent the last month or so making a non-euclidean physics engine. Damn professors, with their fancy "analytic solutions." :P

So people in the GameDev journals have been posting beautiful screens of their real-time global illumination demos. Migi's got his voxel cone tracing thing he's doing, eppo's got whatever voodo he's been up to lately. What you guys didn't know was that CulDeVu has been making a global illumination demo of his own! It's pretty much the latest-tech start-of-the-art stuff happening over here!

Some screens!

So by now you're probably thinking something along the lines of "CulDeVu, how exactly do you make such beautiful images of spheres and cubes?!" It's a company secret, but here's a quick little FAQ, if you were wanting to buy into the business.

How fast does it render?
Usually 8-10 hours for a good render, 30 minutes - 1 hour for a pretty decent one.

Does it support .FBX files?
Don't get your hopes up! It doesn't even load .obj files!

Well, does it do subsurface scattering?
Nope.

Well what about volumetr--
Nope.

Does it even use the GPU?
Pfft. In your dreams.

Well, can it even do--
Jesus Christ, what do you think this is, RenderMan? Jeez...

Awesome! And thank you smile.png

 

I'd love to see the development!

Assimp! Its pretty damn good at what is does. However it doesnt load fbx files! :P

 

Im just wondering what happens behind the sphere with the lines in the first image with the shadows. I'm probably just missing something smile.png

Understandable. The file format specification makes a little part of my want to cry :(

Those white lines on the sphere are actually glowing. You can't see it too well because there's no bloom filter. That's why the reflections on the floor are so pronounced, and you can see the weird thing happening with the shadow because the ball has the same two glowing lines on the other side :)

 

As for development, idk. I want to try out the voxel based stuff you're working on, but I'm not confident enough that I won't screw it up somehow, so I'll make it on the CPU side first, because it's easier to make and debug :P

Ohh ok, that makes sense!

 

Voxels dont bite, but they dont like us! :P
