Method and system for dynamically generating view dependent rendering elements from a static adaptively sampled distance field

Abstract

A method dynamically generates rendering elements for a graphics model. The model is first converted to an adaptively sampled distance field including surface cells representing a surface of the model. A visibility element is determined for each surface cell. A set of active cells is determined, where each active cell is associated with one of the surface cells of the adaptively sample distance field, and each active cell has a corresponding visibility element. Rendering elements are determined for each active cell. Active cells are added and deleted from the set of active cells dynamically according to a weight determined for each active cell by a weighting function. The weight of each active cell can depend on viewing and shading parameters. Rendering elements are dynamically generated when active cells are added to the set of active cells and dynamically deleted when active cells are deleted from the set of active cells.

Dependencies are inferred from the claim text.
