Transparency

Recommended Posts

Does anyone know of any sites or explain to me how to have a graphics semi transparent, like fog or clouds, using directx 7 (direct draw)?

First of all, it''s called translucency.
Second, there are a few tutorials in the articles section.
I don''t remember exactly what section it''s under, but probably
graphics&theory(?)...oh, and you''re most likely looking for
alpha-blending...

However, if you haven''t figured out how to retrieve and plot
pixels in directdraw yet, I suggest you find out how to do that
first.

Good luck ^_^

Inserts standard 'learn about colour' link here: *Splonk!*
EDIT: Also, look up Perlin Noise. Here's Hugo Elias' site, which describes it, clouds and other pretty things.
