Abstract
A method produces an image from a set of discrete sample points. The sample points can define a 3D volume or surface. Each discrete sample point is projected to a screen space. A continuous resampling filter for each sample point is generated in screen space. The continuous resampling filter is a combination of a continuous reconstruction function and a continuous filter function for the sample point in screen space. The continuous resampling filter is then applied to each corresponding discrete sample in the screen space to generate a continuous sample for the image. The continuous samples can be rasterized to pixels using any known rasterization process or method.
