Abstract
An image texturing system utilizes theme cells to generate terrain image data area-by-area for a dynamic terrain display. The system is effective in flight simulation apparatus, as for training pilots. A memory stores theme maps representing areas of specific terrains, e.g. terrains lying below a flight path. The theme maps are indexed on a square grid pattern and include a feature identification code (FIC) for each grid point to indicate terrain, e.g. forest, water, etc. A selection device controlled by an image generator selects a current theme map and dissects it cell-by-cell as defined by grid points to provide corner-referenced representations for each theme cell. A terrain storage device stores a library of terrain treatment pattern arrays that are derived, for example, from photo data of forest, ocean, or the like. A terrain treatment pager controlled by the image generator provides representations of select terrain treatments indicated for a current theme cell and selects the terrain treatment required for texturing the current theme cell. A theme element assembler receives the representations for the current theme cell and the select terrain treatments. The cell is specifi…
