Melting phenomenon reality simulation method based on physics

Abstract

The invention relates to a melting phenomenon reality simulation method based on physics. The melting phenomenon reality simulation method is suitable for modeling of a melting phenomenon in the natural world and comprises the steps that 1, the solid-to-liquid particle relation, heat transfer model, heat source radiation temperature model calculation mode of an object are established according toa particle model; 2, a liquid drop surface tension model is calculated by using a smooth particle fluid dynamical model and an interface theory of mechanics; 3, after liquid drops are generated, an adhering strength model when flow exists between the liquid drops and a solid also needs to be established so as to complete real flow of the liquid drops, and then a real effect is drawn. By adopting the melting phenomenon reality simulation method, a melting phenomenon protecting details can be quickly obtained, and the heat transfer model, a surface tension model constraining liquid drop behaviors and the adhering strength model embodying melting flow, which are needed for object melting, are designed. The melting phenomenon reality simulation method can achieve reality simulation of common object melting scenes, is simple and good in stability and has a certain practical value.

Description

technical field [0001] The present invention relates to a realistic simulation method of melting phenomenon based on physics, in particular to a graphics animation simulation method based on physics, and some of its technologies involve particle modeling, energy model, surface tension model, interactive algorithm and mechanics-related theory. It is mainly used in three-dimensional realistic simulation of various real objects, especially in entertainment games, movie special effects and other fields. Background technique [0002] Changes in the state of matter are common in life, such as the melting of chocolate, the freezing and evaporation of water, and so on. State change phenomenon special effects are widely used in movies and games. Physics-based realistic simulation of natural phenomena is a very effective way to solve such problems. Although physics-based methods can simulate more liquid interaction behaviors, it is difficult to accurately simulate melting phenomena...
