PRODUCING THREE-DIMENSIONAL GRAPHICS
A system includes a computing device for producing a representation of a graphical element on a two dimensional set of image points. A metric value is calculated for each image point in the two dimensional set of image points. The computer device is configured to assign a visual property to image point in the two dimensional set of image points based upon the corresponding metric value. The computing device is also configured to present the assigned visual properties of the two dimensional set of image points as being offset from another two dimensional set of image points to provide a three dimensional appearance of the graphical element.
