Method based on physical coloring and system thereof

Abstract

The invention discloses a method based on physical coloring, wherein the method includes steps of generating an environment light texture sequence with a micro-surface reflection item by using an environment texture picture; according to the environment light texture sequence, calculating an environment light texture item; applying the added simulated high dynamic scale lighting item to perform contrast control on the environment light texture item, and acquiring the initial reflective color; according to the initial reflective color, calculating the final reflecting color by using a Fresnel effect reflection item; adding the final reflection color to a diffuse reflection color so as to obtain the final light color. The method can improve the lighting model efficiency based on the physical coloring, improve the rendering efficiency, and popularize on a mobile phone or other mobile platforms; the invention further discloses a system based on physical coloring, and has the above beneficial effects.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a method and system based on physical coloring. Background technique [0002] The lighting model based on physical shading can greatly improve the realism of material rendering, and at the same time find the corresponding physical parameter basis for artists when developing materials; it has been widely used in next-generation game engines. [0003] With the popularization of mobile platforms such as mobile phones and the ability to implement games and AR application scenarios on mobile platforms, there is an urgent need to achieve high-quality 3D rendering effects on mobile platforms. However, due to the low operating efficiency of the physical shading-based lighting model on mobile platforms, it has not been popularized on mobile platforms such as mobile phones. Therefore, how to improve the efficiency of the lighting model based on physical shading so that it can be implement...
