Suppose you have a material color:
float object_color[] =
{
DIFFUSE, 0.1, 1.0, 0.2,
SPECULAR, 0.3, 0.9, 0.3,
EMISSION, 1.0, 0.1, 1.0,
SHININESS, 24.0,
LMNULL
};
which has been set with:
lmdef(DEFMATERIAL, 1, 15, object_color);
First, are you allowed to change the EMISSION values (or really any
of object_color's properties) on the fly?
Second, If you can change on the fly, do you need to do a new call to
lmdef every time for the changes to take effect or is the first call
sufficient?
