Shadow rendering method and device and electronic equipment

Abstract

Embodiments of the invention provide a shadow rendering method and device, and electronic equipment. The method comprises the steps of determining a light direction according to a current position of a rendering target; selecting target shadow information corresponding to the light direction from multiple segmentation directions, acquiring a target shadow map according to the target shadow information, wherein the segmentation direction corresponding to the target shadow information is the segmentation direction closest to the light direction; completing the shadow rendering according to the target shadow map; and confirming that the position of the rendering target is changed, and repeating the process to complete the mobile rendering of the rendering target. According to some embodiments of the application, the rendering of the moving object is realized based on the pre-stored hard shadow information of each segmentation direction, so that the calculation amount is saved, and the shadow rendering effect of the embedded terminal on the moving object is improved.

Description

technical field [0001] The present application relates to the field of game development, and specifically, the embodiments of the present application relate to a shadow rendering method, device and electronic equipment. Background technique [0002] Shadows are very important to improve the realism of rendered objects in games. At present, the popular technologies mainly include the following: The first one, casting shadows, is to first render the shadows from the perspective of the light source to the occluder to get the shadows, and then project them to the shadow receiving objects (receiver), so that Apply shadows to uneven surfaces. The disadvantage of this method is that the occluder and receiver need to be clearly known, and the shadow of the occluder itself cannot be rendered, so it can only be applied to simple scenes. The second, shadow depth map (ShadowMap) is a commonly used method for generating real-time shadows. It takes the position of the light source as t...

Problems solved by technology

When rendering an object, you can directly sample and bake the texture to obtain shadow information. The overhead is very small. However, this technology does not support object movement or light source movement, and can only be applied to static scenes.
