Mesh.indexBufferTarget

描述

Mesh GPU 索引缓冲区的预期目标用途。

默认情况下，Mesh 索引缓冲区具有 GraphicsBuffer.Target.Index 使用目标。如果要从计算着色器访问网格索引缓冲区，则需要请求其他目标，例如 GraphicsBuffer.Target.Raw。

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    public Mesh mesh;
    public ComputeShader computeShader;
    void Start()
    {
        // Mark the index buffer as needing "Raw"
        // (ByteAddressBuffer, RWByteAddressBuffer in HLSL shaders)
        // access.
        mesh.indexBufferTarget |= GraphicsBuffer.Target.Raw;
        // Get the index buffer of the Mesh, and set it up
        // as a buffer parameter to a compute shader.
        var indexBuffer = mesh.GetIndexBuffer();
        computeShader.SetBuffer(0, "MeshIndexBuffer", indexBuffer);
        indexBuffer.Dispose();
    }
}
