Problems solved by technology

[0003]However, the traditional method has the following disadvantages: 1. By playing animation, the simulation effect of hair depends on the experience of the 3D modeler; Make different animations; animation playback needs to be saved for each frame, and the storage capacity is large; 2. It can only be used for simple hairstyles. For complex hairstyles, the stability of deformation is insufficient and the sense of reality is not strong; in order to ensure the shape of complex hair, basic hair must be added. The number of strands leads to a larger amount of calculation; for different hairstyles, the selection of the root of the basic hair is also a large workload

Embodiment Construction

[0079] Please refer to Figure 1 to Figure 6 Shown, the preferred embodiment of a kind of hair simulation method of the present invention, comprises the following steps:

[0080] Step S10, setting the initial state of the hair styling, and dividing the hair styling into a fixed area (part attached to the scalp) and a moving area;

[0081] Step S20, generate hair mapping bones based on the hair direction of the fixed area and the moving area; mapping bones is a common method in the field of model animation, and is generally used for human body movement; the number of hair mapping bones can be passed through parameters To determine, in order to improve computational efficiency, tens of thousands of hair points can be mapped to 100 mapped bones;

[0082] Step S30, setting the motion parameters of the hair, and using the motion parameters and the mapped skeleton to simulate the motion of the hair in the motion area.

[0083] This application is also applicable to the motion of a...

Abstract

The invention provides a hair simulation method and system in the field of computer graphics, and the method comprises the following steps: S10, setting an initial state of a hair style, and dividingthe hair style into a fixed area and a motion area ; S20, generating a mapping skeleton of the hair based on the hair trend of the fixed area and the hair trend of the motion area; and S30, setting motion parameters of the hair, and simulating the motion of the hair by utilizing the motion parameters and the mapping skeleton. The invention has the advantage that real-time simulation of motion of complex hair styles is realized.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a hair simulation method and system. Background technique [0002] In film production, animation production and other fields, in order to achieve more realistic effects, it is necessary to simulate hair. For the simulation of hair, the following methods are traditionally adopted: 1. Pre-preparing the playback animation and playback conditions of hair movement, and playing the animation frame by frame to simulate the movement of hair when the playback conditions are met; 2. Using FTL (static follow the leader) and optimizing on FTL The DFTL (dynamic follow the leader) physical simulation method, that is, according to the characteristics of the hair, generate hundreds or thousands of basic hairs, add spring particle constraints to the basic hairs, and then use interpolation on the hair roots of the basic hairs Form hair strands to simulate whole hair. [0003] However, the tradit...
