Viewer optimized model compression

摘要

Technologies may be generally described to provide viewer optimized compression of a model. In some examples, a computing device may receive a request to compress a master model for a viewer. The computing device may determine shape primitives of the master model through use of a shape primitive identification technique such as a random sample consensus (RANSAC) technique. The identified or determined shape primitives may be subtracted from the master model to determine residues of the master model. A processed model may be generated from the residues of the master model and the shape primitives. Visible subsets, visible based on a view cone of the viewer, of the residues and the shape primitives may be selected from the processed model, from which a compressed model may be generated. The processed model may then be used to generate a second view without redetermining the shape primitives.

1. A method executed on a computing device to provide viewer optimized compression of a model, the method comprising:
receiving a first request to compress a master model for a first viewer; determining shape primitives of the master model; determining residues of the master model by removing the shape primitives from the master model; generating a processed model from the residues and the shape primitives; selecting a first visible subset of the residues and a first visible subset of the shape primitives based on a first view cone of the first viewer; and generating a first compressed model from the first visible subset of the residues and the first visible subset of the shape primitives from the processed model, based on the first viewer.
