Best format to create a mesh to inport into blender

Post by erickulcyk » Thu Oct 10, 2013 11:31 pm

Hello,

I am beginning a project to transform a point cloud into a polygon mesh suitable for animation and game playing. My first question would be if something like this exists already? I am new to blender, and I am not sure what the best format to save the mesh to would be or where the description of that file format would be. For reference, I intend on connecting this to a Kinect, so as to extract a mesh and texture mappings from the background scene of a room (not necessarily a person). The pipeline would go something like this:
Kinect data -> point cloud -> polygon mesh with textures -> blender
Any pointers in the right direction would be appreciated.

Thanks,
Eric

MeshLab can do point cloud triangulation AFAIK and should be faster than blender scripts, which are e.g.:

MeshLab can also reduce complexity, not sure if blender can do this point cloud data (it can with verts for sure).

About formats: PLY with verts-only should be fine, as it's better supported than this obviously:

I'm sitting, waiting, wishing, building Blender in superstition...

Thanks for the information. I also found that the Kinect fusion does meshing, however the sdk is closed source so not possible modify. Currently I am going to try using the open source fusion in the pcl, which I hope may also do meshing and try working with it from there.
