Systems and methods for reducing the amount of texture cache memory needed to store a texture atlas by using uniquely grouped refined triangles to create each texture atlas.

Systems and methods for creating a three-dimensional texture atlas

Systems and methods for rendering 2D grids using texture mapping and fragment shaders.

Systems and methods for rendering 2D grid data

A method and apparatus for deleting and rescanning areas of a horizon display on a computer monitor is disclosed. A cursor, controlled by a pointing device such as a mouse, is directed to a first area on the monitor which is adjacent a second area of the horizon which is described to be deleted and rescanned. The cursor is dragged from the first area across the second area while a user pushes the control button of the mouse thereby defining coordinates of an area for which all points are to be deleted. The points in the first area are scanned to designate them as seed points. Such seed points are used to pick horizon points in the second area. Such picked points are then used to fill-in the second area.
