METHODS AND ASSOCIATED SYSTEMS FOR SIMULATING ILLUMINATION PATTERNS

摘要

Systems and methods for simulating illumination patterns on target surfaces in a space are disclosed. The system includes an input component and a simulation component. The input component receives a sampling angular range, a sampling polygon density, and a sampling polygon type. The simulation component traces sampling rays according to the sampling angular range and the sampling polygon density and type within a sampling range. The simulation component can further (1) generate an initial illumination pattern with a plurality of sampling polygon projections on the target surface; (2) assign the same value of an attribute in the sampling polygon projections defined by sampling rays through substantially the same route from the light source to the target surface; and (3) adjust the value of the attribute in the sampling polygon projection defined by sampling rays from different routes by interpolation.

1. A method for simulating an illumination pattern on a target surface in a space, the method comprising:
selecting a light source in the space; determining a sampling angular range, an initial sampling polygon density, and a sampling polygon type; tracing a plurality of traveling paths according to the sampling angular range, the initial sampling polygon density, and sampling polygon type within the sampling angular range, so as to create an initial illumination pattern with a plurality of sampling polygon projections on the target surface; assigning a value of a light attribute to each of the sampling polygon projections; adjusting the value of the light attribute in at least one of the sampling polygon projections by interpolation in response to an event that one of the traveling path hits an object in the space so as to finalize the illumination pattern; and displaying the illumination pattern on a user interface.
