Latest Patents

David H Andrews holds a patent for a "System and method for a data processing pipeline." This invention describes an electronic data processing pipeline system designed for processing encoded control points that represent graphical illustrations. The system consists of several micro-programmed circuit cards, each programmed to execute specific processing operations. The process begins with a command sent to a matrix maker card, which defines a geometrical transformation to be applied to the graphical illustration. The matrix maker card, in conjunction with a matrix multiplier card, calculates a transformation matrix that represents the desired transformation.

The pipeline processes electronic representations of control data points, which include 3D points that correspond to both the vertices of linear edges and the control points for curved edges of the illustration. Each point is encoded to indicate its type, whether it is a vertex or a control point. Additionally, the points are encoded to specify whether the corresponding portion of the illustration should be rendered as a solid figure or a line drawing. The control points are then multiplied by the transformation matrix in a vector multiplier circuit card.

Next, the control points are clipped to the planes of the viewing frustum using clipper cards, and the 3D control points are mapped onto a 2D viewing window by a viewport card. After processing, the clipped control points are exploded to generate multiple small line segments that represent each curved edge of the illustration. This ensures that the edges appear smooth to the viewer. Finally, the appropriate portions of the illustration are rendered as a line drawing, and the processed data is converted into a format suitable for scan conversion.
