Sascha L. Teichmann	223d11df0b	Render blocks through a ring buffer which is a binary heap ordered by descending y coords. This establisches a stream of partial y ordered blocks to reduce the the over all overdraw. Speeds up rendering about 25%.	2014-09-12 12:37:27 +02:00

Sascha L. Teichmann	f83efba3cf	Temporarly converting components to uint16 in interleving is not needed because we are only interested in the bit patterns which are the same as in the signed representation.	2014-09-07 11:07:49 +02:00
Sascha L. Teichmann	8d4f73429f	Eliminated the stupid offset bug in interleaving. Hail to to the unit test.	2014-09-07 10:46:51 +02:00

Sascha L. Teichmann	a8c2a4c55d	Simplified code. Add/substract min value when interleaving. BigMin still broken.	2014-09-07 09:58:09 +02:00
Sascha L. Teichmann	6e958e4ff6	Be more clever in testing BigMin. This shows that the interleaving code has shift all values to be positive, so it's broken atm. :-/	2014-09-07 00:18:28 +02:00
