mesh.geometricD() & mesh.bounds().span()?

Alisa_W · January 27, 2019, 09:54

Hello,

Recently, I am working on the modification of quantities about mesh. However, when I analyzed the code of similar files, I really cannot understand the meaning of some functions, such as mesh.geometricD() and mesh.bounds().span().

Although I cannot understand them, I know they are all very brilliant ideas and will save me time in the following work. Can anyone kind to help me understand them or guide me where to find their definitions? Thanks a lot! Wish you all have good time!

Hello,

as far as I understood goemetricD() returns the vector of non constraint directions. So, e.g. if you have an empty patch in x-direction the con constraint directions would by y and z.

bounds() simply returns the bounding box, i.e. the minimum and maximum x-,y- and z-coordinates.
