[GEM-dev] Just a simple question (for a change)

Hi all,
So I have a prototype system with a dynamic array of squares that
clip/offset the texture to create the illustion of one texture on all
squares. I tried making many squares (40x30) and that crashed pd. (my
dynamic patcher did that is). So in order to simulate some kind of
softness with fewer squares I was thinking about using an alpha channel
for each square?
So the question is:
Can I apply the RGB texture using certain texture coordinates, and then
apply an Alpha texture, using different pix_coordinate settings? Since I
would want the alpha channel to clamp to the edges of the geo and not
slide off as the RGB texture does...
I think its impossible since the RGB and A are considered the same
"texture".
Also I realized I think the video source will be YUV anyhow...
Say, does v4l provide YUV or RGB?
I'll make a vertex array version also, but that would have the same
issues with hard-edges and textures...
Any brilliant ideas about making the geos soft?
Thanks,
B.
