Document Type and Number:
WIPO Patent Application WO/2024/021557
Kind Code:
A1
Abstract:
A reflected illumination determination method, comprising: determining intersection point information of intersection points between virtual light emitted by each pixel and a target object (101); performing spherical harmonic transform on multiple pieces of intersection point information corresponding to a target pixel among the pixels to obtain an initial illumination spherical harmonic coefficient of incident illumination distribution of the target pixel (102); performing spherical harmonic transform on an incident direction of the virtual light corresponding to the target pixel to obtain an initial direction spherical harmonic coefficient of the target pixel (103); performing noise filtering on the target pixel on the basis of the initial illumination spherical harmonic coefficient to obtain a target illumination spherical harmonic coefficient after the target pixel is filtered (104); and determining target reflected illumination of the target pixel on the basis of the target illumination spherical harmonic coefficient, the initial direction spherical harmonic coefficient, and the reflectivity of the target object (105), so that the global illumination effect is improved.
