Abstract
Computer graphics methods, systems, apparatus and computer program code (software) products comprise: constructing a sparse implicit scene representation, wherein the representation is independent of geometric encoding and complexity of the input scene description, and the density of the resulting finite elements is proportional to their contribution to the final image to be generated, such that the geometric resolution of a given area of the obtained scene representation is proportional to its importance relative to the final image, wherein the constructing comprises using a Monte Carlo or quasi-Monte Carlo path tracing method to sample an adjoint importance distribution function and to shoot importons from a simulated camera into the scene, recording, for each simulated bounce, a particle i defined by selected information, the selected information comprising: 3D position p, surface normal n, and reflectance factor p.
