Embodiment 1

[0057] figure 1 It is a flow chart of the rendering method provided by Embodiment 1 of the present invention. The technical solution of this embodiment is applicable to the situation of rendering a scene to generate a rendered image, and the method is executed by software or hardware configured in a smart device, such as a mobile phone, a computer, a PAD or other smart devices with graphics processing functions implement. Such as figure 1 As shown, the method specifically includes the following steps:

[0058] S101. Acquire the low-resolution rendering image, the target resolution texture image, and the low-resolution texture image of the target scene, the low-resolution texture image and the low-resolution rendering image have the same resolution, and the low-resolution texture image is the same as the low-resolution image The resolution of the render map is lower than the resolution of the target resolution texture map.

[0059] The target scene is the scene that the use...

Embodiment 2

[0072] figure 2 It is a flowchart of a method for extracting a low-resolution texture map in the rendering method provided by Embodiment 2 of the present invention. In this embodiment, the preset target resolution value is further judged before acquiring the low-resolution texture map. Such as figure 2 As shown, the low-resolution texture map acquisition method includes:

[0073] S1001. Determine whether the preset target resolution value is higher than the preset resolution threshold, if yes, trigger execution of S1002, otherwise, execute S1003.

[0074] The preset resolution threshold in this embodiment can be set according to actual conditions, such as the effect requirements of the result rendering image, the performance of the rendering device, and the rendering speed requirements.

[0075] S1002. Trigger generation of a low-resolution texture map.

Abstract

The embodiment of the invention discloses a rendering method, device and engine, and a storage medium. The rendering method comprises: obtaining a low-resolution rendering graph, a target resolution texture graph and a low-resolution texture graph of a target scene, wherein the resolutions of the low-resolution texture graph and the low-resolution rendering graph are the same; extracting the light sensation distribution changing information of the low-resolution rendering graph relative to the low-resolution texture graph to generate a light sensation distribution change chart; performing super-resolution recovery of the light sensation distribution change chart, and generating a target resolution light sensation distribution change chart, wherein the resolutions of the target resolution light sensation distribution change chart and the target resolution texture graph are the same; and fusing the target resolution light sensation distribution change chart and the target resolution texture graph, and obtaining a result rendering graph. The problem is solved that the generation of the result rendering graph with high resolution is time-consuming in the prior art, and the technical effect is achieved that the rendering time is reduced while the rendering effect is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of rendering, and in particular, to a rendering method, device, engine, and 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 effects, and obtain better rendering effects. ...
