Problems solved by technology

However, this method requires the CPU to cut the viewing volume once, which consumes CPU performance. In addition, the projected model needs to be rendered again. If the model has a large number of faces, it will cause relatively large CPU overhead.

Abstract

The invention relates to the field of image processing, in particular to an environment shielding rendering method, an environment shielding rendering device, a computer readable storage medium and electronic equipment. The environment shielding rendering method comprises the steps of determining and marking pixel points, located in a projection space, of a target object as sampling points; projecting the sampling points to a perspective space through perspective transformation, and determining a texture map based on world coordinates of the sampling points; and determining an environment shielding rendering value of the sampling point, and rendering an environment shielding image corresponding to the target object according to the environment shielding rendering value and the texture map. According to the environment shielding rendering method, the expenditure of the CPU can be reduced while the environment shielding effect is simulated.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to an ambient occlusion rendering method, an ambient occlusion rendering device, a computer-readable storage medium, and an electronic device. Background technique [0002] In real-time rendering applications, when the character is indoors or inside a large area of ​​shadow, the contrast between light and shade is lost under the feet. For PCs or game consoles, the ambient occlusion effect of screen space is generally used to solve this problem, but on mobile platforms, due to performance and heat limitations, a lighter solution is required. [0003] In the prior art, two methods are usually adopted to solve this problem: [0004] One is to use a patch, by creating a patch under the character's feet, and using a circular texture to take alphablend for drawing. However, this method may cause wrong occlusion relationships when the ground has slopes or unevenness, or soft ...
