Abstract

This paper presents a technique for rendering inward looking projections. We call these projections anti-perpsective because they run counter to normal perspective projection and converge to a point in front of the image plane. A real world analog for this type of projection is the reflection seen on a spherically concave mirror. In fact the technique can be used to render reflections on perfectly spherically curved mirrors. Our implementation builds on environment mapping work that captures a sample of the light coming into a point; we propose an inward looking spherical camera that captures a view from all around an object. The aim of this research is to provide a visualisation technique capable of viewing multiple sides of an object in a single image.
