T-Buffer™ Benefit: Soft Reflections
Soft reflections are the result of a surface being uneven at a very fine level, literally having a distribution of normals or micro-facets
Soft reflection benefits:
- Much greater realism for common “semi-gloss” surfaces
- satin finished wood
- stainless steel
- glass and perfect mirrors only have 1 normal, therefore Soft Reflections effect does not apply
Implemented by rendering multiple times with varying normals if you have ray tracing hardware; or can be “hacked” by rendering perturbed reflections...
