Illumination image generation method and device, equipment and medium

Abstract

The embodiment of the invention relates to an illumination image generation method and device, equipment and a medium. The method comprises the steps: building a plurality of GPU particles in a virtual space; obtaining the position of each GPU particle in the virtual space, and drawing a particle model used for representing an illumination area at the position of each GPU particle; based on the position relationship between each particle model and the irradiated object in the virtual space, screening a plurality of target particle models, and determining an illumination range corresponding to each target particle model; According to the illumination range corresponding to each target particle model, rendering each target particle model to obtain a virtual illumination range image, and fusing the virtual illumination range image with a scene image corresponding to the irradiated object to obtain an illumination image of a virtual space. According to the embodiment of the invention, the calculation amount of the electronic equipment is not increased while the virtual scene needing a large number of point light sources is met, the electronic equipment with various performances can be compatible, and the interface display effect of the virtual scene on the electronic equipment is optimized.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a method, device, device and medium for generating an illumination image. Background technique [0002] During the game development process, adding different real-time light sources to the game space can improve the scene image display effect of the game space, such as increasing the realism of the game scene. [0003] Currently, the number of real-time light sources that can be added in the game space is very limited, for example, usually 2-3 real-time light sources, which cannot satisfy game scenes that require a large number of point light sources. Moreover, in the process of image rendering, the more real-time light sources are added, the more resource consumption of the electronic device will be consumed, resulting in a sharp drop in the performance of the electronic device. Even if the deferred rendering strategy is adopted, the complexity of deferred...

Problems solved by technology

[0003] At present, the number of real-time light sources that can be added in the game space is very limited, for example, usually 2-3 real-time light sources, which cannot meet the game scenes that require a large number of point light sources

Moreover, in the process of image rendering, the more real-time light sources are added, the more resources will be consumed on the electronic equipment, resulting in a sharp drop in the performance of the electronic equipment

Even if the deferred rendering strategy is adopted, the complexity of deferred rendering is proportional to the product of the number of image pixels and the number of light sources, and the amount of calculation is still very large
