Description

Parameters that configure a culling operation in the Scriptable Render Pipeline.

Obtain a ScriptableCullingParameters struct by calling Camera.TryGetCullingParameters.

Note that you can obtain and view a ScriptableCullingParameters struct from a Camera in the Built-in Render Pipeline; however, changing the values has no effect.

The following Scriptable Render Pipeline code demonstrates how to obtain a ScriptableCullingParameters struct from a Camera using Camera.TryGetCullingParameters, configure the struct, and then pass the struct to ScriptableRenderContext.Cull to obtain a CullingResults struct. You can then use the CullingResults struct in a call to ScriptableRenderContext.DrawRenderers.

using UnityEngine;
using UnityEngine;
using UnityEngine.Rendering;

public class ExampleRenderPipelineInstance : RenderPipeline { public ExampleRenderPipelineInstance() { }

protected override void Render(ScriptableRenderContext context, Camera[] cameras) { // Get the culling parameters from the desired Camera if (cameras[0].TryGetCullingParameters(out var cullingParameters)) { // Change culling parameters to configure the culling operation cullingParameters.cullingOptions &= ~CullingOptions.OcclusionCull; cullingParameters.isOrthographic = false;

// Schedule the cull operation CullingResults cullingResults = context.Cull(ref cullingParameters);

// Place code that schedules drawing operations using the CullingResults struct here // See ScriptableRenderContext.DrawRenderers for details and examples // …

// Execute all of the scheduled operations, in order context.Submit(); } } }
