Traditional computer graphics rendering engines are designed to carry out linear planar projections. This article presents a method to perform nonlinear perspective projections and 3D view deformation. The existing work regarding nonlinear deformation primarily focuses on abstract models, 2D image distortion and magnification. The nonlinear projections and implementations still remain largely unexplored in 3D environment. The article explores several methods for using nonlinear perspective projections to generate deformed 3D visual effects. An experimental system based on these methods has been developed and tested. Discussed approaches open up possible applications and opportunities in conceptual design, 3D computer games, various training systems, and scientific visualization.
