Re: [JAVA3D] Can multi texturing do this: Alpha + RBG = RGBA?

[Yazel, David J.]

Yes it is.  Currently multi-texturing is only using a MODULATE blending.  This means the two textures are multiplied together.  So assuming you had two textures A and B, and A had an alpha of all 1's and B had all 0.5, then the resultant texture would be 0.5 for all the alpha's.   What you can't do it merge two textures together based on an alpha map and multitexturing, which is generally what people want to do.  So for example you cannot achieve a result for the red channel by (RedA * AlphaA) + (RedB (1-AlphaA)).   David Yazel Cosm Development Team http://www.cosm-game.com -----Original Message----- From: Allan Andersen [mailto:[EMAIL PROTECTED]] Sent: Friday, September 21, 2001 1:07 PM To: [EMAIL PROTECTED] Subject: [JAVA3D] Can multi texturing do this: Alpha + RBG = RGBA? Hi,   Using multi texturing is it possible to "bake" a texture where the two ingrediens are a RGB texture and a ALPHA texture, where the results appears to be a "RGBA" texture which is applied to some geometry.   Allan Andersen
