Introduction

Welcome to use this repo for colored pointcloud sampling from mesh such as .obj

Usage

1. Install requirements

~$ pip install -r requirements.txt

2. Run test

Because I have no time to refactor whole project to match such as *.obj file, please just see the test.py script for more using details
~$ python test.py

Example how to use the mesh2pcd parser

Hi @Xelawk,

I followed the discussion in this issue here and I found your repository. I am interested to create a point cloud from a textured obj mesh.

Initially I used the following code:

pcd1 = o3d.geometry.PointCloud(mesh1.vertices)
pcd1.normals = mesh1.vertex_normals
pcd1.colors = mesh1.vertex_colors

but since the mesh1 has the color information as uv texture coordinates the last command failed to work. Thus, I was wondering whether you parser can do that and if yes, whether it would be easy for you to provide an example.

Thanks.

AttributeError: 'Scene' object has no attribute 'area_faces'

Trying to run this with:

    import trimesh
    mesh = trimesh.load_mesh(str(file_path_input))
    samples, face_idx, colors = trimesh.sample.sample_surface(mesh, 50000, sample_color=True)

results in this error:

    face_weight = mesh.area_faces
AttributeError: 'Scene' object has no attribute 'area_faces' ```

Am I doing something wrong or does this code not work anymore with version 0.18.0 of open3d?
