Abstract
A system for display of interfaces within a block of raw data values comprises a model building portion groups data points into a cubes, receives a threshold and identifies cubes which a vertex data values which straddle the threshold. These are surface cubes. Gradient vectors for each vertex of each cube are determined by comparing the change in data values in three dimensions in a neighborhood around each vertex. The surface cubes and their associated gradient vectors are stored as a cube/vector model. his model may be tessellated and then displayed by conventional CAD/CAM workstations. A second display system is shown which employs a modified 'Dividing Cubes' method to subdivide the cubes, interpolate each to a center point and associated vector, then backprojected to produce perspective.
