Hi everyone,
I'm relatively new to OpenGL programming and am looking for ideas on how to render artistic brush strokes. By that I mean brushes with an alpha channel, varying opacity and color. Bumpmaps for texture would be a plus! Anyone who's used Photoshop or Painter probably knows what I mean.
I've made a little program based on the OpenGL superbible that uses DrawPixels to paint, but I'm not sure if that's going in the wrong direction.
Perhaps anyone knows of a simple opensource application with this feature or a tutorial I can have a look at... The Gimp is a bit unwieldy, I've no idea where to look!
Some hints to get me started would be appreciated.
Thanks,
Stefan
