Here's a bit of a spot light effect. The effect is drawing a full screen tile map to one FX image, then drawing some inverted (sort of) gouraud triangles to a second image. The pair are then merged during the blit image process. It's certainly a bit of a huge mouthful for my trusty duron 800mhz, but should be more than viable on faster machines. This one's an MMX only effect.

The effect is running full screen here, you could selectively limit it to only blit the 'visible region' with a bit of clever coding


Hmm, I wonder what's coming in 2011?

And here's an alpha particle effect blended with the same blit routine. It makes the particles sort of morph into each other. Very cool when running..
