Filed:

Aug 19, 1999

Appl. No.:

09/377442

Inventors:

Lenny Low - Hillsborough CA
Chris Goodman - Fremont CA

Assignee:

Space Systems/Loral, Inc - Palo Alto CA

International Classification:

F28F 1900

US Classification:

165 41, 16510433, 165168

Abstract:

Heat dissipating apparatus for use in dissipating heat produced by electronic components of a spacecraft. The heat dissipating apparatus comprises first and second radiator panels each having an outer panel faceskin 18 and inner panel faceskin. A heat pipe matrix is disposed between outer and inner panel faceskins of each radiator panel, and a honeycomb core is disposed between the inner and outer panel faceskins that surrounds the heat pipe matrix. A transverse panel interconnects the first and second radiator panels. A plurality of crossing heat pipes extend between and thermally couple to the heat pipe matrices of the first and second radiator panels. The plurality of crossing heat pipes extend outside the plane of the transverse panel.

Abstract:

A method for rendering polygons in a computer graphics system in which the computer display is divided into a plurality of subregions, and the rasterization process is performed in a micro framebuffer for each subregion, rather than sending raster data for each triangle into the frame buffer. Each polygon undergoes a first stage bounding box intersection test to identify the subregions which are likely to intersect with the polygon. If the number or configuration of intersected subregions exceeds a predetermined threshold requirement, then the polygon undergoes a more precise second stage intersection test to identify which subregions are actually intersected by the polygon. If the number or configuration of intersected subregions is below the threshold requirement, then the control data for the polygon is passed on to each of the identified subregions.
