Symbolically integrate a function(x,y,z) across a triangle or mesh. |
-
trimesh.integrate.substitute_barycentric(function)¶
-
trimesh.integrate.symbolic_barycentric(function)¶ Symbolically integrate a function(x,y,z) across a triangle or mesh.
- Parameters
function (string or sympy expression) – x, y, z will be replaced with a barycentric representation and the the function is integrated across the triangle.
- Returns
evaluator (numpy lambda function of result which takes a mesh)
expr (sympy expression of result)
Examples
In [1]: function = ‘1’

In [4]: expr Out[4]: 1/2
In [5]: result = integrator(mesh)
In [6]: mesh.area Out[6]: 34.641016151377542
