I download the 3d assets from Sketchfab. I currently use Meshlab to Mesh all the layers of a 3d model together and then export it as a .ply file.
I am trying to learn and follow tutorials on building Pointclouds.
Please help me out.
.ply files have never been supported in SOPs. Due to SOPs CPU-based nature, they are not the right tool to work with point clouds.
.ply files have been available to load into TOPs for years, and more recently POPs as well, both families are GPU based. All common point cloud workflows in TouchDesigner use these 2 families and tons of tutorials for these approaches exist. If you could share which tutorial you are referring to that uses SOPs for point clouds, we can comment on the validity of the approach.
If you really need your POP data in SOPs, you can always use a POP to SOP to convert, but again this is the wrong path for point clouds. Furthermore if you are just starting out with TouchDesigner, we’d highly recommend spending your time studying POPs geometry and not SOPs, POPs supercede SOPs.
