Document Type and Number:
WIPO Patent Application WO/2022/161319
Kind Code:
A1
Abstract:
A shadow mapping processing method, comprising: acquiring model data and light source information of at least one object in a virtual scene, and acquiring a shadow map having a first resolution and corresponding to each object; determining a corresponding second resolution according to the model data of each object; determining, in parallel and by using rasterized pixels of model data under the second resolution, a shadow edge formed by each object under impact of the light source information; calculating the distance from the rasterized pixels to the corresponding shadow edge of each object in parallel, in order to obtain distance data corresponding to each object having the shadow map of the first resolution; and correspondingly storing in the shadow map of the first resolution the distance data corresponding to each object, in order to obtain a distance field shadow map corresponding to each object. Also disclosed are a shadow mapping processing apparatus, a device, a computer-readable storage medium, and a program product.
