I am currently working with models containing millions of faces, and the time it takes to import these into Blender is killing me. The models I am creating cannot be decimated without losing needed detail, and the entire model changes with each iteration (i.e. I create a completely new models on a regular basis).
Once imported the viewing speed is fine, but importing from .ply files takes an obscene amount of time. Here are a few speed tests, run on a Win7 machine with 32GB ram & Intel 2600k processor:
Blender importing binary .ply file (86MB): 89 seconds
Blender importing text .ply file (142MB): 152 seconds
MeshLab importing binary .ply file (86MB): 3 seconds
MeshLab importing text .ply file (142MB): 6 seconds
I’m aware that having the import code written in python would probably be somewhat slow, but 30x slower is a lot. I’ll be working with files easily 5x larger than that tested as well.
Does anyone know an appropriate place that I could put in a request for import speed improvements? This isn’t a bug, and I haven’t found a good place to post something like this.
