Mesh.RecalculateBounds

参数

描述

Recalculate the bounding volume of the Mesh and all of its sub-meshes with the vertex data.

修改顶点之后，应调用此函数以确保包围体正确。 分配 triangles 会自动重新计算包围体。

using UnityEngine;

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

Unity can only recalculate the bounding volume for Meshes that use the default VertexAttributeFormat.Float32 vertex position format. If your Mesh uses a non-standard vertex position data format, you must assign the bounds manually.

The bounds of a SkinnedMeshRenderer cannot be recalculated, and can only be changed by setting the SkinnedMeshRenderer.localBounds manually.
