Abstract
A method of generating a model for 3D printing, includes selecting a target object within a virtual environment; sampling the target object to form a point cloud, the point cloud comprising points corresponding to an outer surface of the target object and also one or more internal features of the target object; rendering the point cloud from a plurality of viewpoints using voxels in place of the points in the point cloud; detecting which voxels and hence which points of the cloud were rendered over the plurality of renders; forming a surface-only point cloud comprising those points of the cloud that were rendered; and generating a model for 3D printing based on the surface-only point cloud.
