mesh.Mesh.hollow#

Mesh.hollow(wall_thickness: float, resolution: int = 80)#

Create a hollow shell from a closed triangulated surface mesh.

This method generates a hollow version of the input mesh by creating an inward offset surface and subtracting it from the original mesh.

Parameters#

wall_thicknessfloat: Desired thickness of the shell. Must be greater than zero and small enough relative to the overall size of the mesh.
resolutionint, default=80: Resolution of the implicit offset grid. Higher values produce a more accurate inner surface but increase computation time and memory usage.

Returns#

Mesh: A hollow triangle mesh with the same outer shape as the input.

Notes#

The input mesh must be valid closed triangle mesh.
