Antialiasing sprites with DirectDraw<=7

Damián Gabriel Paz Adderly · 2002-12-04T01:37:12

For 2D games. 1.Have you done it? 2.How did you handle it? 3.For which system? (microprocessor, videocard) 4.How many sprites and what performance did you achieved? I know these days you can use 3D hardware, but also these days you have Gigs of processing power to handle this without 3D hardware, and since DirectX 8.1 doesn''t support Software Rendering anymore there are still lots of people who will be unable to play a game with 3D hardware requirements.

Ok, I''ve decided what to do.

I''m going to make the artwork in PNG and load this files with libPng, then I''ll store the data into a DDraw Surface and calculate the alphachannels by hand when copying to the backbuffer.

I''ll use DirectX 5 for this. Somebody knows if I can store the alpha information in DirectX5 surfaces in 16bit mode?
