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.
