Abstract

The invention relates to an image rendering method and device, electronic equipment and a storage medium. The method comprises the steps acquiring a three-dimensional model of a target object; determining a two-dimensional pixel point of the target object, a reflection vector of a corresponding point after illumination in the three-dimensional model and an original roughness, wherein the two-dimensional pixel point is a pixel point projected to a screen by the three-dimensional model; performing variation trend analysis on the reflection vector to obtain variation trend information of the reflection vector; smoothing the original roughness based on the change trend information to obtain target roughness; and rendering a two-dimensional image of the target object on a screen based on the target roughness. According to the embodiment of the invention, the anti-aliasing effect can be improved, the quality of the rendered image can be improved, and the anti-aliasing processing is carried out in the image rendering process, so that the generation of additional calculation amount or additional storage occupation can be avoided, the resource consumption of equipment can be effectively reduced, and the performance of the equipment can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image rendering method, device, electronic equipment, and storage medium. Background technique [0002] Physically Based Rendering (Physically Based Rendering, PBR) refers to a collection of rendering technologies based on basic theories that are more consistent with the physical principles of the real world to varying degrees. In PBR rendering, ambient lighting is a very important step to improve rendering quality. However, when using a high-dynamic range image (High-DynamicRange, HDR) map for ambient lighting rendering, some obvious aliasing will be found in the rendering results of the model. [0003] In related technologies, in order to solve the problem of jaggedness and distortion in the rendered image, a series of corrections are often performed based on the rendered image result, so that the jagged part of the rendered image becomes smooth. Howev...
