   Determine mesh rotations to minimise overhangs for 3D printing.

---------------------------------------------------------------------

Installation

 

Install from the GitHub repository:

git clone git@github.com:dpohanlon/mesh-tumbler.git
cd mesh-tumbler
pip install .

Usage

 

Mesh Tumbler uses projections of the normals in the -z direction to
determine the amount of unsupported overhangs above a user defined
thereshold (by default 45 degrees). The mesh is rotated according to
a Bayesian Gaussian process optimisation procedure in order to find
the rotations that minimise the number of these overhangs. The only
argument required to the executable is the path to an STL file:

mesh-tumbler --input_file path/to/mesh.stl

and the rotations about the [x, y, z] axes, along with the value of
the optimised function, are printed. This also takes optional
arguments of the number of function calls to make to the optimisation
function, n_calls, and the pitch of the voxelised mesh, pitch, which
are useful to optimise the time taken to achieve reasonable results.
The maximum angle above which a the projection is considered an
overhang can also be specified with max_overhang_angle.
