Hi

I've got a question concerning the new Dot3-Texture-Combine mode.
I slightly got the feeling that something is not right with it.
The third combine source doesn't seem to have any effect on the
final result. If I've understood it right the Dot3-Combiner works
this way first it calculates the dot3 product between the first
two sources and then saves the results in the r,g,b components.
This result will be used to calculate another dot3 product
with the third source and the final result is again saved in
the r,g,b, right? So the funny thing is I've got following
constellation:

First source Texture_Color
Second source Constant_Color (1.0f, 1.0f, 1.0f)
Third source Previous_Texture_Unit_State

The Texture used as first source is constant filled with RGB
255/255/255  (which would be 1.0f, 1.0f, 1.0f) the third
source uses a real grayscale texture. But the result I see on
the screen is just a complete white object. I'm using the
Win32/OpenGL implementation of J3D1.3beta1 on a Geforce2MX400.

Another question is it possible to deactivate the third source
I don't really see a real use for it. Better 2 or 4 sources
but 3 is in my opinion quite useless. Or use the third
source rather as modulate/multiply combine instead of dot3

EOF,
 J.D.
