Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
119 words
Method of providing an image on an electronic display, characterized by: (a) encoding the image as a series of data elements corresponding to coordinate locations; (b) storing the data elements in a first memory; (c) generating a first scan pattern; (d) selecting a scan transformation; (e) generating a secondary scan pattern by modulating the first scan pattern; (f) obtaining the data elements corresponding to the secondary scan pattern from the first memory; and (g) displacing the secondary scan pattern to generate representations of third dimensional image features by modulating the secondary scan pattern with predeterminted bits of said data elements to thereby provide an image signal showing displacement from the secondary scan pattern for display on a display surface.
Claim 2
Dependent Claim
119 words

Claim 3
Dependent Claim
20 words
Method as described in claim 1 further characterized by: storing said secondary pattern in a second memory for subsequent readout.
Claim 4
Dependent Claim
36 words
Method as described in claim 2, further characterized by: the readout of said secondary pattern being accomplished by said reading of the scan pattern; and said reading effecting a raster scan of the secondary scan pattern.
Claim 5
Dependent Claim
53 words
Method as described in claim 3, further characterized by: the modulation of the secondary scan pattern displacing the display from the secondary scan pattern to provide representation of third dimensional features on a two directional display medium in which the third dimensional features are displaced from the secondary display pattern prior to displacement.
