We present a general method for automatic reconstruction of accurate, concise, piecewise smooth surface models from scattered range data. The method can be used in a variety of applications such as reverse engineering—the automatic generation of CAD models from physical objects. Novel aspects of the method are its ability to model surfaces of(More)
We describe an efficient method for constructing a smooth surface that interpolates the vertices of a mesh of arbitrary topological type. Normal vectors can also be interpolated at an arbitrary subset of the vertices. The method improves on existing interpolation techniques in that it is fast, robust and general. Our approach is to compute a control mesh(More)
A videokeratograph quantifies one or more aspects of corneal shape by the computer analysis of a digital image. The image is the reflection formed by illuminating the cornea with a known source pattern. The type of shape information recovered and the accuracy of this information depend upon properties of the computer algorithm used in the analysis. We(More)
