- FUNCTION :
- ----------
- File Visual3d_Light :
-
- Declaration of variables specific to light sources
-
- NOTES:
- ----------
-
- A light source is defined by :
- - type
- - color
- - reduction factors ( for positional and spot only )
- - its angle ( for spot only )
- - its concentration ( for spot only )
- - its direction ( directional and spot only )
- - its position ( positional and spot only )
-
- It is active in a view, in the associated context.
-
- ATTENTION:
- ----------
-
- - AngleCone is given in radian [Pex] while OpenGl works in
- degreees. The limits for Pex are [0,PI] while for OpenGl this is [0,90].
- - Two reduction factors are used with Pex while OpenGl uses three.
- - The ereduction factors have range [0.0,1.0] for Pex and
- for OpenGl the range is [0.0,n]
- - The concentration varies from [0.,1.0] for Pex to [0,128] for OpenGl.
