openGL

What am I supposed to pass to PF_GET_CGRAF_DATA to get an HDC for a Layer_Def?

Nothing I put as the last argument works. My compiler keeps barfing when trying to convert anything to a void ** - even if I try to cast it manually.

Can I even grab the HDC for an effect world, and draw to it with openGL?

Thanks,

You can't.

You'll need to do the translation between OpenGL-ville and AE-town, usually pixel by pixel.

Figured that was the case. I wound up opening my own hidden opengl window and copying it pixel by pixel into output just as you suggest. It's nice because I get all of opengl's drawing tools, but the more I've been thinking about it, I'm not sure I want to force my plugin users to have to have certain video cards, or updated drivers... Plus opening windows and such seems like it'll make having a windows and a mac version more complicated.

Welcome to the world of supporting the opengl [ahem] "standard"...

;)

All the more reason why AE should provide at least a few basic primitives. Points, lines, circles and triangles (filled and unfilled, with antialiasing options) would certainly help me. Or they would've, but I'm almost done making my own library of drawing tools. I'm sure you guys could do a much better job at it than I can though.

Oh well, writing my own gives me something to do at night while my wife watches bad TV.
