Abstract

The invention discloses a picture rendering method and device, a storage medium and an electronic device. Wherein, the method includes: obtaining the first depth information of the object pixel corresponding to the target object in the multi-light source scene in the target picture to be rendered; obtaining the second depth information corresponding to each target light source in the multi-light source; according to the first Depth information and second depth information, determine the pixel point of the target object from the pixel points of the object, wherein the location of the pixel point of the target object is within the illumination range of at least one target light source; perform illumination calculation on the pixel point of the target object, and obtain The result of the lighting calculation that matches the pixels of the target object; render the target screen according to the result of the lighting calculation. The present invention solves the technical problem that the operation complexity of picture rendering is relatively high when forward rendering is used to perform picture rendering for multi-light source scenes.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a picture rendering method and device, a storage medium and an electronic device. Background technique [0002] In order to present a picture in a three-dimensional scene on a computer device, a rendering technology is usually used for picture rendering. Among them, rendering includes forward rendering (Forward Rendering) and deferred rendering (Deferred Rendering), where forward rendering is currently a rendering method with a relatively wide range of applications. [0003] However, when the forward rendering method is used for image rendering, the calculation amount of lighting calculations for pixels in the image tends to increase with the increase of the number of light sources in the scene. For example, when using the forward rendering method to render and color n objects under m light sources in the scene, the computational complexity is O(n*m) times. That is to say, when...
