Feature request(?): exporting DAE with face colouring

[jrjhealey]

I'm currently using meshlab to transfer vertex colours (from protein models) to their faces. I'm doing this so that the colours can be visualised with the Augmented Reality tool Augment.

The process at the moment is quite tedious and doesnt lend itself to automation (which I would ideally like).

The easiest format for use with Augment is a COLLADA/DAE format file. However, so far the only tool I've found which 'correctly' formats the daes such that Augment renders them properly is Blender.

This means the work flow at the moment looks like:

• Export as a VRML file from the protein modelling software.
• Import in to meshlab
  • Copy the vertex colours to the faces
  • Perform edge decimation, preserving normals, model boundaries and topology
• Re-export the meshlab mesh as a Wavefront object so that the MTL files are also generated.
  • Exporting is done, ensuring colouration for vertices and faces is ticked.
• Import the OBJ+MTL in to Blender, and resave the whole thing as a DAE.

I'd like to be able to omit the Blender step if meshlab is capable of outputting a DAE with face colouring somehow? Perhaps this is a feature request.

If possible, I'd appreciate it if someone might be able to tell me the equivalent meshlabserver commands to perform vertex to face colour transfer and quadratic decimation to a specific number of faces (with normals/topology/boundary preserved).

It would be great if Meshlab could handle DAE face coloring.

I need to check the results from files that I generated myself using pycollada. So for me it would be sufficient if Meshlab could visualize the face coloring after opening an COLLADA/DAE-file.
