findSuitableGridSize

public static int[] findSuitableGridSize(CacheSpec cacheSpec,
                                         int maxMemoryInMB)

Find suitable size of a 3D texture (in multiples of cacheSpec.paddedBlockSize()) such that it requires less than maxMemoryInMB, the texture is roughly square, and fits as many blocks as possible.

Parameters:

cacheSpec - provides voxel type and size of an individual block.

maxMemoryInMB -

Returns:

size of 3D texture in multiples of CacheSpec.paddedBlockSize().
