Abstract

The embodiment of the invention discloses an obtaining method and device of a rendering image, a rendering system and a storage medium. The method comprises the steps of obtaining a low-resolution rendering image and a target-resolution texture image which are generated by a rendering engine of a target scene; generating a low-resolution texture image according to a preset rule; extracting light sensation distribution change information of the low-resolution rendering image relative to the low-resolution texture image to generate a light sensation distribution change image; conducting super-resolution restoration on the light sensation distribution change image to generate a target-resolution light sensation distribution change image; merging the target-resolution light sensation distribution change image with the target-resolution texture image to generate a resultant rendering image. The problem in the prior art that generation of the resultant rendering image with a high resolutionis time-consuming is solved, the technical effects that the rendering effect is guaranteed, and the rendering time is shortened at the same time are achieved, and the rendering efficiency is improvedthrough the cooperation of the rendering engine.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of rendering, and in particular, to a method and device for acquiring a rendered image, a rendering system, and a storage medium. Background technique [0002] Graphics can express various information intuitively, and have a large capacity and are easy for people to obtain. With the rapid development of computer software and hardware, the application of computer graphics in various industries has been rapidly popularized and deepened. [0003] However, graphics with realistic effects often need to be rendered, and the rendering time in the prior art is often directly proportional to the image pixels. For example, the Monte Carlo method based on ray tracing is an extension of the traditional ray tracing algorithm. Approximate the rendering equation through the method of probability and statistics, which can support more surface material effects and simulate global illumination effec...
