d1bcaec2c5 This commit knocks about 30% off the run time of the sampler tests by using a more efficient check for whether we are near the edge of the chunk. 2015-04-02 23:11:19 +02:00

65f39e7b57 Made the values signed ints, as otherwise the casting was doing something strange on 64-bit systems. 2015-04-01 16:29:19 +02:00

7f96005985 Commented out optimized path in sampler as it doesn't work now that we are using Morton ordering for the data in chunks. However, we can probably reinstate such a fast path if we give some thought as to how it should be done. 2015-03-29 09:58:28 +02:00
