  • No way that's real time... is it?

  • Yes, it's real-time. But there is a problem with the recording program so the fps down when the mouse move.

  • You see how there's a black aura around the claws when they're over his body? Needs z-test.

  • Since when do you need to bake the texture for SSAO? AO is calculated using a depth buffer, I don't think anything needs to be baked.

  • he looks horny.

  • Is this the same type of Occlusion used in Halo: Reach?

  • Gotta love SSAO it's so simple yet looks so great

  • what creature it that????

  • @QuaziGNRLNose Basically, what u have said is roughly the  first-gen SSAO algorithm's idea. However, that is already out-dated. Much more sophisticated methods have already been published.

  • if im right this just uses the zbuffer texture, for each pixel, checks the differences in z for the pixels surrounding it in and adjusts said pixels darkness based on how far "back" this pixel is compared to its neighboors (a large difference being darker?) but has a falloff curve so that the effect wont apply on things with too large a difference (foreground pixels against background pixels?) anyone care to clear things up?

  • POWERFULL

  • Is this the 3d unsharp masking method?

  • Apparently there is a z test, but the drop-off is too high.
