UNH's VR Point Cloud Editor Tutorial

Contributed by Beatrice Hoang


Point clouds are a set of data points in space. They're often used to represent 3D objects/models. Point clouds are generally generated by 3D scanners or other model-capture techniques that measure surface information of objects.

Not all point clouds that come from a 3D scanner will be nice and clean - they often collect unwanted noise or outliers that shouldn't be included in the final model. UNH's VR Point Cloud Editor allows you to import a point cloud as an .las/.laz file and remove that unwanted noise using your controllers. Once you are done cleaning, the model can be exported.


Note: Complete these steps on Paperspace machine

In color, the bird model looks like:

Your goal is to use UNH's editor to remove the base the bird is sitting on. The final product will be the point cloud of just the Lego bird.

Optional: if you would like to use your own 3D point cloud model, you can use an app like Poly.Cam to capture your own point cloud model. Follow steps here for instructions on using PolyCam. Make sure you export the model as a .laz file.

Note: when opened in the editor application, the point cloud will not be in color (even though the laz file contains color information for each point). Be familiar with the model's geometry so you know what you need to remove.
