Abstract

A system combines 2D and 3D modeling in rendering shapes and includes: a 3D modeling factory to generate a 3D model of selected shape parameters or features; a front face factory to generate 2D text and text effects, and some 2D shape effects; a ground plane factory to generate effects that are rendered on a ground plane of a shape; and a rasterizer/compositing engine to combine 2D and 3D effects generated by the front face factory, ground plan factory, and the 3D modeling factory.
