Problems solved by technology

The three-dimensional effect of the model rendered by this method is more in line with the physical highlight effect in the real scene, but the painting effect is poor
If hand-painted highlights are used for rendering, the rendering efficiency is low

Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0029] In a real-time non-photorealistic rendering (Non-photography Rendering, NPR for short) scene, a complete rendering result generally includes direct lighting and indirect lighting, and direct lighting includes two parts: diffuse reflection and specular reflection. The specular part of the light is also called the highlight part, which has a great influence on the light and shadow effect of...

Abstract

The invention provides a highlight rendering method and device of a model and electronic equipment. The method comprises the following steps: calculating an initial highlight parameter of a target model through a preset illumination model; acquiring a shape gradient parameter of the target model; wherein the shape gradient parameter represents the relative position between the vertexes of the target model; adjusting the initial highlight parameter based on the shape gradient parameter to obtain a highlight parameter of the target model; and performing highlight rendering on the target model based on the highlight parameters. According to the method, the rendering effect has a certain drawing style while ensuring that the rendering effect of the highlight approximately conforms to the anisotropic law, the effect requirement of an unreal rendering scene is met, and meanwhile, the rendering efficiency of the highlight is also improved.

Description

technical field [0001] The present invention relates to the technical field of model rendering, in particular to a model highlight rendering method, device and electronic equipment. Background technique [0002] In the virtual scene of non-photorealistic rendering, it is necessary to simulate the artistic expression effect of painting while the model expresses the highlight effect. In related technologies, when performing non-photorealistic rendering, the highlights of the model may be rendered based on an illumination model such as an anisotropic highlight model, or by hand-painted highlights. However, in the process of rendering highlights using the lighting model, the irradiance of the highlights is usually calculated based on the tangent data and normal data of the model to be rendered. The calculation results follow the anisotropy law, and then the highlights of the model are calculated according to the calculated irradiance. rendering. The three-dimensional effect of...
