Using 3D in 2D... DiscoStew (0 replies, 0 views) (2001-Feb-18) I have been working on a project for some time now, and I have decided to use D3D for some 2D effects. I have everything ready to go (rotating, scaling, alpha-blending, etc.) but I have run into a problem. Since I have been using 2D, I thought that perhaps I should Blt images onto a texture surface so that I could let D3D do the dirty work. Unfortunately, this is very costly. Having to Blt (or should I say BltFast) onto the texture surface decreases my FPS a lot.
I need to know a fast way of getting data from a normal surface onto a texture surface without having to make all the surfaces texturized. Anyone out there have any ideas? |
