  • System and method for correctly decimating height fields with missing values
    Patent number: 6760023
    Abstract: Simplifying a surface represented as a height field. The simplification resulting in a triangular mesh having n vertices, such that the topology of the surface is maintained in the simplified surface representation. The simplification including assigning error values to each vertex not having a missing value, identifying as required vertices those vertices that may not be removed without altering the topology of the surface; and (1) if n is less than or equal the number of required vertices, remove all other vertices or (2) if n is greater than or equal the number of required vertices, remove u-n vertices, where u is the number of vertices that do not have missing values in the original height field.
    Type: Grant
    Filed: March 22, 2002
    Date of Patent: July 6, 2004
    Assignee: Schlumberger Technology Corporation
    Inventors: Andreas G. P. Hubeli, Richard P. Hammersley
  • System and method for multi-resolution fairing of non-manifold models
    Patent number: 6693631
    Abstract: A method of fairing a non-manifold model as disclosed which includes smoothing the model by applying a fairing operator to a set of features such that noise is removed after determining the features of the model.
