COORD_TYPE: cylinder #5

Thanks for your open-source code! Don’t we identify “shape missing" areas in a spherical coordinate system? Why set COORD_TYPE = cylinder?

Hi Yzichen, my original version before paper submission uses the spherical coordinates that costs more GPU memory, which i'm only able to run on better GPUs than 1080 ti. During code release, to accommodate the hardware conditions of broader audiences, I later implemented this community version which partitions the space by "cylinder" (the logic of occlusion is also adjusted a bit for cylinder). It can achieve similar results. The performance difference is minimal and it is much more efficient in memory space usage.

I get it, thanks for your reply ！
