用Unity做简单的有限元分析效果

说明：我就是用到了，写了个简单的方法。本方法比较笨，但是很容易理解。可以在这个基础上优化。

一、获取Mesh顶点位置，并在顶点生成用于控制的小球

ChangMesh.cs（pointsFather是小球的父物体，随便找个空物体就行。）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ChangeMesh : MonoBehaviour
{
   
   
    public GameObject pointsFather;
    private Mesh mesh;
    private GameObject newPoint;
    private Vector3[] vertices;

    // Start is called before the first frame update
    void Start()
    {
   
   
        pointsFather.transform.position = this.transform.position;
        mesh = this.GetComponent<MeshFilter>().mesh;
        vertices = new Vector3[mesh.vertices.Length];
        CreatMeshPoint();
    }

    private void CreatMeshPoint()
    {
   
   
        for (int i = 0; i < mesh.vertices.Length; i++)
        {
   
   
            vertices[i] = mesh.vertices[i];
        }
        for (int i = 0; i < mesh.vertices.Length; i++)
        {
   
   
            GameObject creatPoint = GameObject.CreatePrimitive(PrimitiveType.Sphere);
            creatPoint.transform.localPosition = vertices[i];
            creatPoint.transform.name = "EditorPoint" + i.ToString();
            creatPoint.transform.localScale = new Vector3(0.01f, 0.01f, 0.01f);
            creatPoint.transform.parent = pointsFather.transform;
