Per-pixel lighting for shaders

[dylanede]

The Lambert and Phong shaders calculate lighting per-vertex. This results in poor lighting for meshes with low vertex density. There really is no need for this on modern hardware.

[kvark]

This is not true. Phong shaders are evaluating lighting on per-pixel basis:

Line 36 in 78e0534

float dot_nl = dot(normal, normalize(dir));

Is there a particular quality issue you are concerned about? Or just sharing the observation?
