|
||
|
|
*
|
||
|
|
* Renders lighting information directly instead of final shaded colors.
|
||
|
|
* The information keys allow the selection of either normal rendering or
|
||
|
|
* luminance. For normals, the (nx, ny, nz) tuple are rendered directly into
|
||
|
|
* the (r,g,b) fragment. For luminance, the diffuse and specular intensities are
|
||
|
|
* rendered into the red and green channels, respectively. The blue channel is
|
||
|
|
* zero. For both luminances and normals, the alpha channel is set to 1.0 if
|
||
|
|
* present.
