Abstract

The invention relates to an OpenGL-based transparent object delayed rendering method, which relates to the technical field of delayed rendering, and comprises the following steps of: when rendering a transparent object, firstly, arranging rendering numbers of the transparent object according to the sequence of transparency from small to large, and rendering according to the sequence of the numbers; for the objects with the same transparency, determining the arrangement rendering numbers of the objects according to the object texture complexity; after the arrangement rendering numbers of the objects are determined, adjusting the arrangement rendering numbers of the objects according to the rendering contour areas of the objects; when the arrangement rendering numbers of the objects are adjusted, rendering the objects; and correcting the adjusted object arrangement rendering number according to the color depth of the object. The method is not influenced by the number of light sources in a scene when rendering the transparent object, and the rendering sequence of the transparent object is controlled by , so that the rendering efficiency of the transparent object is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of delayed rendering, in particular to an OpenGL-based delayed rendering method for transparent objects. Background technique [0002] At present, mainstream deferred rendering is limited to non-transparent objects. Transparent objects still use forward rendering. First, the efficiency of traditional forward rendering will be affected by the number of light sources in the scene. Since objects are in a transparent state and cannot be affected by light, for transparent objects, Engines generally use normal rendering for processing. Of course, there are also engines that store transparent point information and disassemble them during processing. However, due to the limitation of RT space, there will inevitably be some losses, resulting in low rendering efficiency, followed by anti-aliasing. Because anti-aliasing needs to sample information from other surrounding points, in the prior art, one way is to u...
