ABSTRACT:
A graphics processing and display system includes a coordinate sensing system for determining position and orientation of a view point reference with respect to a schematic representation of at least one three-dimensional object; a view point controller for controlling a display view point according to the determined position and orientation of the view point reference with respect to the schematic representation; and a display processor for generating pixel data representing a two-dimensional rendering of the at least one three-dimensional object according to the graphics data and display view point, wherein the two-dimensional rendering is different from the schematic representation, and wherein the pixel data generated by the display processor is output for display on a display device. Advantageously, the system of the present invention is efficient and easier to use than prior art graphics processing and display systems because the user is provided the ability to control the display view point according to the position and orientation of the view point reference with respect to the schematic representation of the displayed object.
