BatchCullingContext.ViewID

描述

发起剔除的对象 ID。用法示例：为每个对象存储与剔除相关的数据。

// Example of per-view data, indexed by view ID

using System;
using UnityEngine;

public class CullingExample : MonoBehaviour
{
    private BatchRendererGroup batchRendererGroup;
    private Dictionary<BatchPackedCullingViewID, MyViewData> myPerViewData = new Dictionary<BatchPackedCullingViewID, MyViewData>();

    void Start()
    {
        batchRendererGroup = new BatchRendererGroup(this.OnPerformCulling, IntPtr.Zero);
    }

    public JobHandle OnPerformCulling(
        BatchRendererGroup rendererGroup,
        BatchCullingContext cullingContext,
        BatchCullingOutput cullingOutput,
        IntPtr userContext)
    {
        if (!myPerViewData.ContainsKey(cullingContext.viewID))
        {
            // If the data doesn't exist for the current view, create it.
            myPerViewData[cullingContext.viewID] = new MyViewData();
        }
        MyViewData currentViewData = myPerViewData[cullingContext.viewID];

        // Do stuff with the current view's data.

        /* You can also get the instance ID of the current view's gameObject
           (for example, Camera, Light, etc.) as follows: */
        int instanceID = cullingContext.viewID.GetInstanceID();

        /* The slice index depends on the view type.
           For example, for Cameras, the slice index is always zero.
           For cascaded shadow maps, it equals the index of the cascade. */
        int sliceIndex = cullingContext.viewID.GetSliceIndex();
    }
