#432 Meshlab can't open the canonical ply file

[Jeremy Herbert]

Meshlab can't open the canonical ply file, as written by Greg Turk (the inventor of the format). The file is described here:

http://www.cs.virginia.edu/~gfx/Courses/2001/Advanced.spring.01/plylib/Ply.txt

and is as follows:

ply
format ascii 1.0
comment author: Greg Turk
comment object: another cube
element vertex 8
property float x
property float y
property float z
property red uchar
property green uchar
property blue uchar
element face 7
property list uchar int vertex_indices
element edge 5
property int vertex1
property int vertex2
property uchar red
property uchar green
property uchar blue

2 3 255 255 255
3 0 255 255 255
2 0 0 0 0

When I open this file in meshlab 1.3.3 on OSX, I get the error "Bad type name".

Thanks,

There is a problem with the color properties of the vertices.

property uchar red
property uchar green
property uchar blue

Should have been, I think:

property red uchar
property green uchar
property blue uchar

This one does work fine:

ply

comment object: another cube
element vertex 8
property float x
property float y
property float z
property uchar red
property uchar green
property uchar blue
element face 7
property list uchar int vertex_indices
element edge 5
property int vertex1
property int vertex2
property uchar red
property uchar green
property uchar blue
