Abstract

The invention discloses an interactive ink simulation method based on fluid mechanics and GPU optimization rendering. The technical problem that an existing ink simulation method does not have real-time performance, diversity and unpredictability of a real ink fluid motion simulation process can be solved. The method comprises the following steps executed by computer equipment: realizing fluid motion simulation based on a stress rule of a particle individual; introducing interaction information as external force, and achieving simulation of ink fluid flow law; adopting a GPU Compute Shader tocarry out optimization operation; adopting a GPU programmable pipeline for scene drawing, adopting a GPU Shader for directly obtaining a calculation result, and meanwhile rendering the content of a virtual scene. According to the invention, the interaction and flowing rules of the static and moving states of the ink fluid and the relative movement between the fluid and the solid boundary wall arerealized, and various interaction elements are introduced, so that a brand-new deductive form is provided for the traditional ink culture and art works, and brand-new visual experience is provided for ordinary people.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to an interactive ink simulation method based on fluid mechanics and GPU optimized rendering. Background technique [0002] Fluid mechanics is a branch of mechanics, which mainly studies the static state and motion state of the fluid itself under the action of various forces, as well as the interaction and flow law when there is relative motion between the fluid and solid boundary walls. Fluid is a general term for gas and liquid, which can be encountered anytime and anywhere in people's life and production activities. Therefore, fluid mechanics is closely related to human daily life and production. The movement of water in pipes, channels, and rivers has been the subject of research since ancient times. People also use water to do work, such as ancient water reels and modern highly developed water turbines. Ships have always been people's means of transportation. Vario...
