here's how the sprites work now:
- black is transparent
- no pure white
- all other colors 'pasted' to the map
- the overall dimensions of the image are used for distance calculations, nothing fancy like looking at the actual image data. this helps for the clumping effect i was discussing earlier
- 24-bit uncompressed tga
- sprites are blurred after they are placed on the map with a pass of the gaussian blur
not sure how specific i need to be, i think that covers all of the major stuff without getting too technical. if you have a set of colors to use for the background you'd like to see used with them, send those along too. i'm sure your sprites will be better than the crap ones i put together in a few spare seconds.
btw, i think i may have found a compiler to handle mac/linux apps, havent looked at it yet though.
