Title: Physically-based lighting model for objects
Post by: angrypig on May 14, 2012, 09:18:28 am

Hi guys,

here is video with the latest material shader for objects. In this video the ambient is too dark because wrong sky color comming into shader. The grass is older version so there are some issues with culling and the terrain self-shadowing is not perfect too :) but all stuff is WIP...

Basic BRDF description:
- blinn-phong for distribution term
- Schlick's approximation for geometry term
- specular normalization
- diffuse energy conservation

Looks stunning to say the least!

Will this work automatically on all models? Should have spawned the iss if you want to to REALLY show off frame-rate shattering shadows!

NASA wants their lighting technology back. ;D


Anyway great effect. ;) I'm am amazed with this lighting model, especially when you look at sun and edges of mesh are very nicely lighted.

It is basic material shader and it is default for all objects and i'm going to make faster versions of the shader for slower GPUs. Current version is not optimized yet but is able to hande a few ISSs. :D
