Ive being working on a engine using direct3d to render sprites onto the screen. I use colorkeyed transparency to remove the areas around the sprite. I was wondering if theres any way (through hardware) to anti alias the edges of the drawn region. Anti aliasing edges with SetRenderState only removes the edges around a polygon, but since the sprites is in the middle of a polygon with transparent areas around it wont work.

Hi

When you use Textured Quads for your Sprites, you could use an Texture with alpha channel, to make the Areas around the sprite Transparent. That way you do the Antialiasing in your 2D Painting Programm.
