ABSTRACT:
A bit map image is stored as a two-dimensional array with z axis set arbitrarily at unity. Total rotation transform and screen projection is then treated as a lumped equation due to multiplicative associativity so long as only one variable "V" is included in each lumped equation. The z-data (stored elevation values corresponding to each bit map x/y coordinate) is re-inserted as a later operation after the image has been partially transformed and projected.
Full yaw, pitch, and translations from virtually any perspective viewpoint may be projected onto a multiplicity of screen shapes (conical, spherical, flat, etc.), with z data being inserted into a final output.
