Problems solved by technology

[0004] The above methods all need to use more than two textures and also need a special light map baking program to re-bake the light map. The production process is very cumbersome and error-prone

Embodiment Construction

[0034] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0035] figure 1 It is a flowchart of a method for realizing light map dynamic lighting according to the present invention, and the following will refer to figure 1 , to describe in detail the method of the present invention for realizing dynamic lighting of light maps.

[0036] The main light source means the light source that has been baked in the light map and needs dynamic lighting, and the type and number are not limited.

[0037] The light map described in the embodiment is the most commonly used light map that records the diffuse reflection results of all light sources, that is, the light map obtained by the traditional light map baking method.

[0038] In t...

Abstract

The invention provides a method for realizing light patch dynamic illumination, a storage medium and a computing equipment. The method comprises the following steps that the main light source of the light patch is stripped off, and the illumination result of other light sources is separated out; the ambient diffuse reflection of the light patch is separated; the illumination result of the main light source is calculated again; the illumination result of the main light source is added with the illumination result of other light sources and the ambient diffuse reflection. The method, the storagemedium and the computing device for achieving the dynamic illumination of the light map are provided, so that the three-dimensional scene does not need to be re-baked again, and the original single-tension map can be continuously used. The dynamic change of the main light source and the dynamic high-light reflection and high-precision normal labeling effect can be achieved, and the environment shielding of the original light map is kept.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for realizing dynamic lighting of light maps, a storage medium and a computing device. Background technique [0002] Light maps are usually used for complete static lighting, that is, the position, color, and brightness of the light source are fixed, and the lighting result does not change with the diffuse reflection result of the viewpoint position, and cannot describe the specular reflection that varies with the viewpoint. Due to the capacity limitation of disk and video memory, the resolution of light map is usually low, which cannot show high-precision normal map effect. [0003] To achieve dynamic adjustment of light source color brightness and highlight reflection, an independent mask image is usually set for the light source that needs to be dynamically changed to mark the area affected by the light source (the black area in the figure is equivalent to th...
