Chamfer tool for volumetric sculpting

A computing device comprising:

• a processing device;
• and
• a computer-readable medium storing instructions that, in response to execution by the processing device, cause the processing device to:
• receive an indication of a brushed region of a three-dimensional (3D) object to be chamfered and a chamfer size;
• determine, by a machine-learning model, parameters for an edge voxel or a corner voxel on a surface of the 3D object in the brushed region, the parameters defining a chamfer plane and a chamfer coefficient;
• move, based on the chamfer size and the chamfer coefficient, the chamfer plane for the edge voxel or the corner voxel in a direction normal to the chamfer plane;
• and
• perform an addition or subtraction operation on the 3D object to the chamfer plane for the edge voxel or the corner voxel to generate a chamfer.

A system comprising:

• means for receiving an indication of a region of a three-dimensional (3D) object to be chamfered and a chamfer size, the region including multiple voxels in a voxel grid;
• means for determining, by a machine-learning model, one or more surface voxels in the region that represent an edge voxel or a corner voxel of the 3D object;
• means for determining, by the machine-learning model, parameters for the edge voxel or the corner voxel of the one or more surface voxels that define a chamfer plane and a chamfer coefficient;
• means for moving, based on the chamfer size and the chamfer coefficient, the chamfer plane for the edge voxel or the corner voxel in a direction normal to the chamfer plane;
• and
• means for performing an addition or subtraction operation on the 3D object to the chamfer plane for the edge voxel or the corner voxel to generate a chamfer.
