Embodiment Construction

[0053] The specific implementation process of the method of the present invention will be introduced below with reference to the accompanying drawings. figure 1 Flowchart of a method for generating a controllable flame animation.

[0054]The most complete description of fluid phenomena is the Navier-Stokes equation. Using the NS equation, the fluid motion model that meets the physical conditions can be calculated and has a high sense of reality. There are two main methods based on physics: the first method starts from the study of the motion at each fixed point in the space occupied by the fluid, and analyzes the velocity of the fluid at each fixed point in the space filled by the moving fluid, The change of parameters such as pressure and density with time is a grid-based method; the second method is to start from the analysis of the movement of each micro-group in the fluid, that is, to study the velocity, pressure, density, etc. of a specified micro-group in the fluid. The...

Abstract

The invention discloses a controllable flame animation generation method and a controllable flame animation generation system. The controllable flame animation generation method comprises the steps: 1. obtaining flame-simulated grid data field through a method of using physical modeling or actual measurement; 2. injecting particles at neighboring areas of burning points by utilizing the grid data field to generate a corresponding particle system, wherein the particles of the particle system move under the driving of the grid data field; 3. importing the particle system into a scene, and adjusting the particle movement trail and particle temperature in the particle system according to control conditions set by a user; 4. reverting the adjusted particle system to a second grid data field, and calculating the grid temperature field of the second grid data field by utilizing interpolation algorithm; and 5. rendering the grid temperature field to generate a flame picture sequence. The controllable flame animation generation method and the controllable flame animation generation system are on the basis of physical simulation data, and can generate animation sequence with better realistic quality at faster speed.

Description

technical field [0001] The invention relates to a control algorithm for flame animation design, in particular to a controllable flame animation generation method and system thereof. Background technique [0002] With the gradual development of fluid simulation technology, various fluid phenomena in nature, such as smoke, water, flame, explosion, etc., are more and more widely used in virtual reality, film and television animation, game entertainment and other fields. Among them, because of the danger of flames, the complexity of motion laws, and the special requirements in practical applications, the simulation of flame phenomena has become a research hotspot in the field of computer graphics. The realistic flame effect can greatly improve the immersion brought by virtual reality technology to users; the flexible control technology of flame can provide film and television animation producers with a broad space for imagination, and fully demonstrate the artist's inspiration a...
