The main goal of sampling in computer graphics is to obtain a digital image from a continuous image description. The unknown continuous image I is typically defined implicitly by the scene's geometry, materials, and the model of light propagation. Two different kinds of sampling are involved in rendering an image: image-space sampling which corresponds to evaluating I at selected positions, and integration sampling which is required to calculate I(x) by solving the rendering equation numerically. The dissertation will focus on the image-space sampling and assume that I(x) can be computed exactly.
