Hem, which red book ? sorrry.
So, if I understand well : "Transparency is best implemented using blend function (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) with primitives sorted from farthest to nearest." ?
Taken from http://www.mevis.de/opengl/glBlendFunc.html

Thanks, tigital and Chris.
By the way, James, should I always replace the Gem that is bundled with Hans installer for your Gem version (from your Mac.com site) ?

glBlendFunc() There is a whole section on it in the RedBook.
Fragment shaders are also useful for this.

Hi list,
I am much playing around with alpha blending in Gem these days and I was wondering how I could change the default blending mode between geos. I think it is feasable with openGL objects, but there are only two openGL examples in the example/help patches.
The default blending mode between geos is "add". I would like to set it to "multiply" in some cases and "mask", so that when we are viewing a geo with a pix texture on it, we don't see the other geos' pix textures behind it ? I am sure this is possible. How ?
