Disperse Pixels creates a visual effect of disintegrating or materializing a mesh or sprite object into/from hundreds to thousands particles via the built-in particle system. Just parent the script prefab to the target renderer object and you are good to go.
Styles of the disperse effect include pixelated, sandy and cloudy (with variant designed for http://powerlisting.wikia.com/wiki/File:Nightcrawlerteleport.gif]ghostly teleport/blink[/url]). There are 21 prefabs in total, and the manual details how to customize your own disperse effect.
Level of detail of the target mesh is irrelevant. Sprite, high-polygon and low-polygon meshes work fine. It does not involve tessellation. Also there are mobile-optimized variants.
