COMMENTS
The ray starts at the center of the tiling and goes through the center of one of the thick rhombs of the central "Sun" patch. The walk types that can occur are encoded as follows:
Walk type | Number
---------------------------------------
along diagonal of thick rhomb | 1
along edge of thick rhomb | 2
along diagonal of thin rhomb | 3
along edge of thin rhomb | 4
