Embodiment Construction

[0083] The embodiment of the present application provides a three-dimensional crack simulation method and a related device for obtaining high-efficiency simulation results without force analysis.

[0084] The L system is a parallel grammar proposed by the Hungarian biologist Aristid LinderMayer in 1968. It describes the structure and growth of plants in a formal language, and has now become an important tool for plant modeling. Later, the L system was developed and applied in the field of computer graphics, and applied to the simulation of three-dimensional fracture topology. Such as figure 1 As shown, the general random L system can be expressed by the formula G=, where V is the character set, ω is the axiom, P is the generation rule, π is the adoption probability of each generation rule, and π: P → (0, 1]. For P i ∈P, i=1,...,n, there are The operation flow of the general stochastic L system is as follows: figure 1 As shown, based on the axiom ω, the corresponding lette...

Abstract

Embodiments of the invention disclose a three-dimensional crack simulation method and a related device, and aim at obtaining three-dimensional crack effect and satisfying simulation applications withrelatively high requirement for third dimension. The method comprises the following steps of: combining initial control points in an initial control point set to obtain N groups, wherein the initial control point set comprises at least two initial control point; calculating path points corresponding to the N groups through a random L system so as to obtain a path point set; establishing target graphs corresponding to the path points in the path point set so as to obtain a target graph set; carrying out topological operation on the target graph set to obtain a three-dimensional crack entity; and carrying out subtract of Boolean operation on the surface of a to-be-generated crack and a three-dimensional crack model so as to obtain a three-dimensional crack effect on the surface.

Description

technical field [0001] The embodiments of the present application relate to the field of simulation, and in particular to a method and a related device for three-dimensional crack simulation. Background technique [0002] The L system is a mature grammar system that can generate graphics based on characters. The L system was originally used to simulate the growth and changes of biological cells, and was later developed and applied in the field of computer graphics. It is often used in the simulation of plant topology and other simulations that generate graphics. The essence of the L system is a grammar, which is a string rewriting system. By treating characters as an operation and performing multiple iterative calculations based on a character set, complex functions such as simulating tree structures can be realized. Since the cracks in the wall have a certain similarity to the branches of trees in form, the simulation of cracks can be realized based on the L system by usin...
