90bfc225b8 When generating shaded tiles draw to pix buffer directly instead of calling Set() for each pixel. Set resize filter for generating pyramid tiles to Lanczos3 because of better visual results. 2014-09-16 00:08:31 +02:00

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

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

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
