[GEM-dev] More Feature Requests posted to Source-Forge

[B. Bogart]

Hey Chris,

I was just guessing as to certain "possible" blend modes since a pixelTANGO user 
asked me about it. (and its one of the few things that Gem will not do that 
aftereffects can (and shadows, but I'm not asking for that!).

I was not aware of "frame" is it in the gemwin help?? suprised I missed it. (duh!)

Ok so what do these blending modes actually do?

> CONSTANT_COLOR
> ONE_MINUS_CONSTANT_COLOR
> CONSTANT_ALPHA
> ONE_MINUS_CONSTANT_ALPHA

Add, subtract, multiply could be pretty useful... there are the pix_ objects for 
these operations but that is less flexible (texture only) and perhaps will end 
up as shaders in the future?

I have still not had a chance to look at these, I'll take a look.

I just thought I'd put it on the map, but I'd much rather get support to load 
alpha channels from files, and that point-in-volume test.

Thanks for taking the time to anser chris, did you see my vertex array requests 
on source-forge?
