Hygoon Mosaic

A texture packer for stills or animations. It is an internal tool developed for Pterodactyl Attack, a game made by Hygoon.

We define a "mosaic" as a densely packed texture of variously-sized cells. We used this to aggressively decrease the footprint of certain animated bitmaps. For example, you can see how we stored an explosion animation below. The "mosaic" is on the left and the animation on the right is pieced together from mosaic cells.
