Direct3D> 2D Part 3, Alpha blending

I'm back, with Part 3 of creating 2D graphics using Direct3D.


Part 3 is built on top of Part 1, still displaying the Mario character running around in circles, but contains some additions which I just found out:

• Alpha blending! (you can change the alpha value, as shown in the demo)
  
• Faster way of faking light! (this time, not using vertex color, but simply drawing a bitmap alpha-blended over the scene, more accurately simulating lighting)
  
• Using DirectDraw in combination with Direct3D! (allowing for large surfaces to be drawn, like the background)
  

The 33 FPS in the screenshot are from my P133, however, if I turn off the background it instantly goes to 60 FPS (the maximum, since that's my monitor's refresh rate)...


Enjoy! And don't forget to leave comments (and vote!)
