i'm using a pixelated image as a texture to a gridshape (opencylinder).
i use the alpha channel of the texture to achieve transparency , so
that one can see inside or even through the cylinder if the pixel
values are dark.
this works fine with blend enable etc.
but only if i look at the cylinder in a certain angle. e.g. if i look
from above down on the cylinder it works, but not if i look from below.
i noticed these "planes" appearing inside the cylinder that finally
"kill" my wonderful transparency.
they are obviously connected to the dimension count - but i don't get
it where/why they come from?
yes, my understanding of openGL is quite limited and i could use a
hint for the right direction.
attached is a patch that hopefully demonstrates what i mean.
give it a slight shove up or down to rotate the cylinder.
