ABSTRACT:
A shadow is generated in a virtual three-dimensional space by adjusting a resolution of a 3D model, projecting elements of the 3D model onto a surface in the virtual 3D space, and rendering a shadow having the adjusted resolution of the 3D model on the surface using the projected elements.
