hello

what i mean with "antialiased GEM output" is, how can i render objects like a sphere, a circle or text in a smoother way.

thanks for your help

Well... the answer is [polygon_smooth]. However, I am not too impressed with the results, or am using it incorrectly. Give it a shot. I've been trying all sorts of tricks to 'smooth' out my GEM patches, none have worked. What I really want is just a set of 'filters' at the output stage. Like, a mastering suite for video. I'm afraid that this does not exist.

thanks nestor,

i tried "polygon_smooth" but nothing changes, either worse nor better.

you could render to a framebuffer/texture that's larger than the window, then have a smoothing/interpolating fragment shader when you render it on a quad in the window, but that might be trickier than somehow enabling anti-aliasing, and i don't know how to do it in Gem.

This is possible with multipass rendering: first render to texture(s), then process texture(s) with fragment shaders to generate final image, repeat as necessary. Not sure how to do it in Gem though.
