But we want our normals to look out, not in.Which resulted in (almost) all normals looking at the point (0, 0, 0) as we requested. First step was Filters > Point set > Compute normals with the following parameters. This operation is called surface reconstruction and can be easily done for example using MeshLab software: Triangles are better than points because once you have them you can compute lighting effects and give volume to your model. It all started in a device similar to this one: The scanner packed me into a point cloud with ~400,000 points, which looks like this:įirst we need to convert point cloud into a mesh: a graphical model, which consists of triangles. And today, to avoid doing all the things I really needed to do, I decided to go through the pipeline from a 3D scan to an animated model. So it happened that yesterday I did a 3D scan of myself.
