Abstract: An image processing method includes generating an initial representation of a three-dimensional environment using a three-dimensional array of elements having a first spatial resolution with respect to the three-dimensional environment; generating a distance field, DF, representation from the initial representation, the DF representation including a three-dimensional array of distance values having a second spatial resolution with respect to the three-dimensional environment; and applying a data compression process to the DF representation to generate a data-compressed DF representation.

Abstract: A shadow rendering method for an image includes: re-projecting 3D coordinates of image pixels from an image space of the image to points on a 2D shadowmap space; estimating at least one of a horizontal and vertical distribution of the points in the shadow map space; for a flexible scale rasteriser ‘FSR’, updating a horizontal or vertical FSR curve corresponding to a distribution of FSR bins for the shadow map so that the corresponding horizontal or vertical distribution of points per bin is most even; and rendering the shadow map using flexible scale rasterization.

Abstract: A method of generating a data set includes determining a vertex count of a reference polygonal mesh, generating a second polygonal mesh by adding a predetermined number of vertices to the reference polygonal mesh, comparing a representation of the second polygonal mesh with a representation of the reference polygonal mesh, assigning a first value of a quality parameter to the reference polygonal mesh, and assigning a second value of the quality parameter to the second polygonal mesh based on the comparison of the representations, the value of the quality parameter for a given polygonal mesh indicative of a degree of difference between a representation of the given polygonal mesh and a representation of the reference polygonal mesh, and generating the data set comprising data indicative of a vertex count for the reference and second polygonal meshes and a value of a quality parameters for the reference and second polygonal meshes.
