Export point cloud #13

Closed HungNgoCT closed 2 years ago

HungNgoCT commented 2 years ago

Hi.

Thank you for your useful code. Is there any ways to export point cloud, such as export to *.ply file?

Regards

Hi, a possible way is to record all points and their weights during rendering. E.g. you can return all sampled points and weights in function render_rays using: return ret, means, weights

If you want to visualize pointed near the surface, just select the one with the highest density along the ray when saving the file.
