|
|||
=> Apply model to atmosphere (aerial perspective)
|
||||
=> Find a proper model for night sky (maybe Shirley)
|
||||
- Clouds should keep distance to ground.
|
||||
- Implement Bruneton's scattering model.
|
||||
- Add fresnel effect to specular lighting.
|
||||
- Add clouds to explorer with 3d textures.
|
||||
- Start using OpenCL to optimize rendering.
|
||||
- Rethink the quality settings and detail smoothing in the distance.
