ABSTRACT:
A method and an apparatus for texture generation for a digital image generator of an aircraft flight simulator is disclosed in which (a selected two of the three) coordinates of each pixel of an image are inverse transformed to earth coordinates (112-124, in FIG. 11) from which addresses are developed (126, 128 and 130) for accessing a texture table (132 and 134) to retrieve elements from which an appropriate pixel intensity is developed (140). The table stores near (132) and far (134) texture, the far texture elements being interpolated to avoid a checkerboard effect, stores a limited number of texture types, the elements of selected texture types being combined (132 and 134) to develop additional texture types, and stores levels of detail (degrees of filtering) the appropriate levels being accessed (126) to avoid aliasing (scintillation of a scene), adjacent levels being mixed (136 and 138) to provide smooth detail level transition.
