Unity - Vertex

기존의 vertex를 random으로 뒤튼다.

using UnityEngine;

public class Example : MonoBehaviour
{
    Mesh mesh;
    Vector3[] vertices;
    void Start()
    {
        mesh = GetComponent<MeshFilter>().mesh;
        vertices = mesh.vertices;
    }

    void Update()
    {
        for (var i = 0; i < vertices.Length; i++)
        {
            vertices[i] += vertices[i] * Random.Range(-100, 100)/100.0f * Time.deltaTime;
        }

        // assign the local vertices array into the vertices array of the Mesh.
        mesh.vertices = vertices;
        mesh.RecalculateBounds();
    }
}

 

using UnityEngine;

public class Example : MonoBehaviour
{
    Vector3[] newVertices;
    Vector2[] newUV;
    int[] newTriangles;

   void Start()
    {
        Mesh mesh = new Mesh();
        GetComponent<MeshFilter>().mesh = mesh;
        mesh.vertices = newVertices;
        mesh.uv = newUV;
        mesh.triangles = newTriangles;
    }
}
