METHOD FOR DISPLAYING THREE-DIMENSIONAL POLYGON ON SCREEN Russian patent published in 2007 - IPC G06T17/40 G08G1/969 

FIELD: technology for displaying three-dimensional polygon on display, wherein three-dimensional polygon, which is geometrically incomplete and therefore may not be displayed on screen by means of automatic triangulation in common three-dimensional graphics library, may be shown on screen.

SUBSTANCE: method includes operation of input of three-dimensional models for producing three-dimensional models with three-dimensional coordinates for area, subject for usage on screen, determined on basis of basic positioning coordinates, determined by positioning of vehicle; operation of reproduction of polygons, during which three-dimensional models, introduced at three-dimensional model introduction stage, are classified, in accordance to whether all vertices of polygon are on one and the same plane for three-dimensional model, and polygons are reproduced for classified models based on aforementioned coordinates of basic position, and operation of displaying of polygons on screen, reproduced in operation of reproduction of polygons on screen.

EFFECT: decreased amount of calculations in common three-dimensional graphics library, improved efficiency of processing time usage.
