having trouble doing antialiasing on polygons. Line smoothing works just fine but how do I do it with polygons?

you have to set the blend mode to alpha saturation and have a destination alpha channel, afaik

How do I do that?

Not sure if you need dest alpha but I think so. see the opengl docs about setting the blend mode. no idea about dx.

e.g

glEnable(GL_BLEND)
glBlend(GL_SRC_ALPHA_SATURATE,GL_ONE)

that may not be the right combo but its along those lines, and this is gl only.
