load mesh from .ply file with custom format

See original GitHub issue

Hi @marcomusy,

I want to load a custom .ply file with different properties and elements structured in the following format:

File: map_mesh.ply
Description:
ply
format binary_little_endian 1.0
comment generated by omnimap
element vertex 3786298
property float x
property float y
property float z
property float nx
property float ny
property float nz
property float radiance_blue
property float radiance_green
property float radiance_red
property float irradiance_blue
property float irradiance_green
property float irradiance_red
property float irradiance_lamp_0_blue
property float irradiance_lamp_0_green
property float irradiance_lamp_0_red
property float irradiance_lamp_1_blue
property float irradiance_lamp_1_green
property float irradiance_lamp_1_red
property float irradiance_lamp_2_blue
property float irradiance_lamp_2_green

property float irradiance_lamp_3_blue
property float irradiance_lamp_3_green
property float irradiance_lamp_3_red
property float irradiance_lamp_4_blue
property float irradiance_lamp_4_green
property float irradiance_lamp_4_red
property float irradiance_lamp_5_blue
property float irradiance_lamp_5_green
property float irradiance_lamp_5_red
property float reflectance_blue
property float reflectance_green
property float reflectance_red
element face 7570727
property list uchar uint vertex_indices
element lamp 6
property list uint uint vertex_indices
end_header

Do you think it would be possible to do that with vedo. I’ve tried to use the following command mesh = vedo.Mesh('./map_mesh.ply') but it seems that my created mesh variable to be empty.

You can access the .ply file from this tarball (apologies for the big size)

if it’s some complementary information I would keep it separate from the mesh, but that really depends on the way you plan to use it. Hope it helps 😃

PS: once map_mesh.vtk is created, vedo takes 0.8 sec to load it:

from vedo import load, show
m = load('map_mesh.vtk').alpha(0.2)
m.selectPointArray('irradiance_lamp_1_red')
print('loaded')
show(m)
