Pygmsh example
It can read and write meshes in Wavefront format (.obj) and perform Boolean operations on meshes. For example, the code for subtracting a torus from a cube is as follows: import meshlib.mrmeshpy as mr. # create a mesh of cube with edge length =1: cube = mr.makeCube(size = mr.Vector3f( 1, 1, 1 )) # create a mesh of torus:Welcome to pygmsh's documentation! ... Elementary geometrical entities can then be manipulated in various ways, for example using the Translate, Rotate, Scale or Symmetry commands. They can be deleted with the Delete command, provided that no higher-dimension entity references them. Zero or negative identification numbers are reserved by the ...
