Title:
VIRTUAL MODEL LIGHTING RENDERING METHOD AND APPARATUS, STORAGE MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/185287
Kind Code:
A1
Abstract:
Disclosed in the present application are a virtual model lighting rendering method and apparatus, a storage medium and an electronic device. The method comprises: acquiring a candidate probe set for a virtual model to be rendered, probes in the candidate probe set being used for performing lighting rendering on the virtual model to be rendered; acquiring the occlusion degree of each probe in the candidate probe set with respect to the virtual model to be rendered; and according to said occlusion degrees, screening the probes in the candidate probe set to obtain a target probe set; and acquiring spherical harmonic basis coefficients of the probes in the target probe set, and according to said spherical harmonic basis coefficients, performing lighting rendering on the virtual model to be rendered. The present application solves a technical problem of low lighting rendering efficiency for a virtual model.
