I was tackling getting color dithering to work for a 600x448 7-color e-paper display.

It was dog slow, taking over a minute to render each frame.

I have no standard template library. I have no std::map I can rely on, much less a kd-tree (i actually have one i just don't know how to use it)

*deep breath* I can do this.

*cracks knuckles*

Aaaand after banging on it for awhile I built a simple hashtable and vector replacement and then used that to dramatically speed up my dithering.

Now it takes seconds to render a frame - totally acceptable for color e-paper.

Big Grin | :-D Big Grin | :-D Big Grin | :-D
To err is human. Fortune favors the monsters.
