Original C++ implementation: normal-position-combination

Install

pip install normal-position-combination

Usage

First you need to have a mesh with (relatively) accurate vertex normals. The method will optimize the vertex positions to better fit the normals.

Process a trimesh.Trimesh Object

import trimesh
import normal_position_combination as npc
mesh = trimesh.load_mesh('./sample_data/panel.ply')
optimized_mesh = npc.process_trimesh(mesh)

Directly Process a Mesh File

import normal_position_combination as npc
npc.process_mesh_file(
    input_filename='./sample_data/panel.ply',
    output_filename='./sample_data/processed-panel.ply'
)

Parameters

Please refer to the original implementation's manual for the detailed explanation of the parameters.
