Hi,
The current training loss does not support training from point clouds; it requires ground truth voxels or point-value pairs for training.
Training implicit field models from point clouds itself is an ongoing research area. I would recommend you to look at this work for ideas: SAL: Sign Agnostic Learning of Shapes from Raw Data https://arxiv.org/abs/1911.10414
However, if your point clouds are dense enough, you can always obtain their correct voxel models for training by:
I see. Thank you for your reply, it is very helpful!! :)
Hi,
I am looking to convert a point cloud to mesh using IMNet.
I am able to reproduce the paper on shapenet dataset. However, when trying to train from scratch or applying transfer learning on my own dataset, I am unable to reproduce the good reconstruction result.
Steps taken so far:
My hypothesis is that my point cloud to voxel conversion is not as good and smooth as the original voxels you have from shapenet. Would you happen to have any idea on how to properly voxelise and get the point-value sampling from a point cloud?
