PLY files with QUAD faces are not read correctly #5

Closed Rabbid76 closed 2 years ago

Rabbid76 commented 2 years ago

The PLY file below cannot be read and causes memory corruption. It seems that reading PLY files with QUAD faces is not implemented yet. See MeshLoader::loadPly:

ply.request_properties_from_element("face", { "vertex_indices" }, index, 3);

Example:

ply
format ascii 1.0
comment Created by Blender 3.0.0 - www.blender.org
element vertex 38
property float x
property float y
property float z
property float nx
property float ny
property float nz
property float s
property float t
element face 10
property list uchar uint vertex_indices

Hi there,

can you please give me some more information on the task you are trying to accomplish? E.g. which function are you testing, and a dummy dataset?
