Abstract: Examples of methods are described herein. In some examples, a method includes determining a graph representation of a three-dimensional (3D) object based on a voxel representation of the 3D object. In some examples, the graph representation includes nodes corresponding to voxels of the voxel representation and edges associated with the nodes. In some examples, the method includes predicting, using a machine learning model, a sintering state of the 3D object based on the graph representation.

Abstract: Examples of methods for point cloud alignment are described herein. In some examples, a method includes orienting a model point cloud or a scanned point cloud based on a set of initial orientations. In some examples, the method includes determining, using a first portion of a machine learning model, first features of the model point cloud and second features of the scanned point cloud. In some examples, the method includes determining, using a second portion of the machine learning model, correspondence scores between the first features and the second features based on the set of initial orientations. In some examples, the method includes globally aligning the model point cloud and the scanned point cloud based on the correspondence scores.
