Mesh.bounds

Description

网格的包围体。

这是网格在其本地空间中的轴对齐包围盒（即，不受 变换影响）。请注意，Renderer.bounds 属性类似，但是返回世界空间中的边界。

另请参阅：Bounds 类、Renderer.bounds

// Generates planar UV coordinates independent of mesh size
// by scaling vertices by the bounding box size

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        Vector3[] vertices = mesh.vertices;
        Vector2[] uvs = new Vector2[vertices.Length];
        Bounds bounds = mesh.bounds;
        int i = 0;
        while (i < uvs.Length)
        {
            uvs[i] = new Vector2(vertices[i].x / bounds.size.x, vertices[i].z / bounds.size.x);
            i++;
        }
        mesh.uv = uvs;
    }
