Abstract: Systems and methods applicable, for instance, to using continuous levels of detail (CLODs) in connection with computer graphic models. Distinct levels of detail (LODs) can be generated, floating point LOD (fLOD) values can be calculated, and interpolated LODs can be generated. Further, LOD display can occur.

Abstract: A system and method for scaling raster images. Digital pictures are stored in a run length encoded (RLE) format. Object specifiers include a picture index and a scale factor. A line fill state machine, or blitter, scales a raster scan line asynchronously of raster scan synchronization signals. A bit slice processor controls the operation of the blitter and vertical scaling. The growth or shrink scaling is performed about a pre-selected center of mass. A double buffered frame buffer allows one frame buffer to be read while the other is written.

Abstract: Apparatus and method for rendering graphic images as bit maps, including: (1) an input for receiving digital input commands; (2) a command interpreter to interpret the input commands and convert them into commands suitable for use inside the system; (3) a halftone screening section; and (4) a rendering section which outputs data suitable for use by a raster display or marking engine. The method and apparatus render multiple output pixels during each clock cycle and apply halftone screens or gray fills to an image.
