Overview of three-dimensional computer graphics
Donald H. House · ACM Computing Surveys · 1996
Three-dimensional computer graphics is called three-dimensional for several reasons.The graphics are generated by constructing a virtual 3D model which is then imaged, employing a physical simulation of illumination in three-dimensional space.Much of the research in the field is aimed at creating an illusion of three-dimensionality. Devices such as perspective, physically realistic shading, focus, atmospherics, and 3D motion for animation have been investigated [Foley et al.
