Failed to assign point cloud vertex color to a mesh

[dongchen-yang]

Hi,

I have a mesh and a point cloud sampled from the mesh. I then assigned some color to the point cloud. I want to transfer the color to the mesh and generate a texture map, but it seems to fail to do so and the generated texture map is completely blank. Any idea for help? Here is the code to reproduce it I have also attached the link for .ply and .obj files.

import pymeshlab
import os

ply = "59.ply"
obj = "59.obj"
ms = pymeshlab.MeshSet()
ms.load_new_mesh(ply)
ms.load_new_mesh(obj)
ms.compute_texcoord_parametrization_triangle_trivial_per_wedge()

mesh_name = os.path.basename(ply).replace(".ply", "")
ms.transfer_attributes_to_texture_per_vertex(sourcemesh=0, targetmesh=1,attributeenum=0,textname=f"texture_{mesh_name}.png")
ms.save_current_mesh( f"{mesh_name}_new.obj")
# print(ms)
