SLOW translucency

BeanDog · 2000-03-11T20:11:48

I used the really neato source code from that really old article that was posted on here a while back about alpha blending and MMX and such. Only problem is, it drastically slows down my game when I want to put down a 320x240x16bpp sprite every frame. I am using MSVC++6.0, DXSDK7.0a, and I want to know how to make a REALLY REALLY fast translucent blit. Any idears? -Ben Dilts PS I need to use stretch/shrink at the same time...

Thanks for the input.

By the way, I know it''s an API, it was about 3 in the morning when I typed that.

D3DX is a good solution for this -- it has a set of functions for sprites which support features like alpha blending through the hardware. In the Dx7 sdk help look at Direct3D->Direct3DX Utility Library->Direct3DX Utility Library Essentials->Sprite Support.
