Adding h5m in memory method #29

Closed shimwell closed 1 year ago

shimwell commented 2 years ago

Work in progress

This should remove the need to write STL files once completed

It goes straight from the meshed Brep to h5m

conda build test failing as it can't find the vertices to h5m package. This is because that package only has a pypi installer currently

shimwell commented 2 years ago

Tests failing with tests/test_two_joined_cubes.brep file not found error

currently missing the trimesh step

mesh = trimesh.load_mesh(filename)
            if mesh.is_watertight is False:
                msg = f"file {filename} is watertight"
                warnings.warn(msg)
            trimesh.repair.fix_normals(
                mesh
            )

this is done in vertices to h5m package
