encode

public static long[] encode(short[] heights,
 int bitsPerEntry)

Creates compressed longs array from uncompressed heights array.

Parameters:

heights - array of heights. Note that for this method it doesn't matter what size this array will be. But to get correct heights, array must be 256 elements long, and at index `i` must be height of (z=i/16, x=i%16).

bitsPerEntry - bits that each entry from height will take in `long` container.

Returns:

array of encoded heights.
