Separate Specular on the Radeon®
|
| |
The RadeonSeparateSpecular demonstrates the difference
between using normal OpenGL® specular highlights and using
EXT_separate_specular_color
highlights. A checkered pattern is applied to a sphere
and three moving spotlights are used to show the differences.
Take note of the black areas of the textures between the
two techniques.
