Abstract
Disclosed is an improved computer system, method, and program product that has one or more input devices for receiving one or more input meshes representing a three dimensional model. The three dimensional model is capable of being represented as a 2-manifold triangular mesh. A conversion process automatically converts the input mesh to a multiresolution quadrilateral-based subdivision surface (MQSS) representation.
Claims16
A computer system comprising one or more memories, one or more central processing units and further comprising:
- one or more input devices for receiving one or more input meshes representing a three dimensional model, the three dimensional model capable of being represented as a 2-manifold polygon mesh;
- and
- a conversion process that automatically converts the input mesh to a multiresolution quadrilateral-based subdivision surface (MQSS) representation.
A computer system comprising one or more memories, one or more central processing units and further comprising:
- one or more input devices for receiving one or more input meshes representing a three dimensional model, being a 2-manifold polygon mesh, each of the input meshes having one or more features, each of the features being a part of the model with a different curvature and scale than one or more adjacent parts;
- and
- a conversion process that automatically converts the input mesh to a multiresolution quadrilateral-based subdivision surface (MQSS) representation.
A computer system comprising one or more memories, one or more central processing units and further comprising:
- one or more input devices for receiving one or more input meshes representing a three dimensional model, each input mesh being a 2-manifold polygon mesh, each of the input meshes having one or more features, a feature being a perceptually important part of the model with a different curvature than one or more adjacent parts;
- and
- a conversion process that automatically converts the input mesh into a multiresolution quadrilateral-based subdivision surface (MQSS) having a base mesh with one or more base mesh edges where one or more of the base mesh edges correspond to one of the features.
