파라미터

cullingResults The set of visible objects to draw. You typically obtain this from ScriptableRenderContext.Cull.
drawingSettings A struct that describes how to draw the objects.
filteringSettings A struct that describes how to filter the set of visible objects, so that Unity only draws a subset.
stateBlock A set of values that Unity uses to override the GPU's render state.
tagName The name of a SubShader Tag or Pass Tag.
isPassTagName If set to true, tagName specifies a Pass Tag. Otherwise, tagName specifies a SubShader Tag.
tagValues An array of ShaderTagId structs, where the name is the value of a given SubShader Tag or Pass Tag.
renderTypes An array of ShaderTagId structs, where the name is the value of a SubShader Tag that has the name "RenderType".
stateBlocks An array of structs that describe which parts of the GPU's render state to override.

설명

Schedules the drawing of a set of visible objects, and optionally overrides the GPU's render state.

This function creates commands to draw the specified geometry, and adds the commands to the internal command list of the ScriptableRenderContext. The ScriptableRenderContext executes all the commands in its internal list when ScriptableRenderContext.Submit is called.

For a full example that demonstrates how to use this function in context, see Creating a simple render loop in a custom render pipeline. This short example demonstrates using a CommandBuffer to set the view matrix, and then calling this function to draw geometry using that matrix:

using UnityEngine;
using UnityEngine.Rendering;

public class ExecuteCommandBufferExample { ScriptableRenderContext scriptableRenderContext;

// Placeholder data DrawingSettings exampleDrawingSettings; CullingResults exampleCullingResults = new CullingResults(); FilteringSettings exampleFilteringSettings = new FilteringSettings();

public void Draw() { // Create a CommandBuffer to set the view matrix Matrix4x4 exampleViewMatrix = Matrix4x4.Scale(new Vector3(2f, 2f, 2f)); CommandBuffer myCommandBuffer = new CommandBuffer(); myCommandBuffer.SetViewMatrix(exampleViewMatrix);

// Schedule the execution of the CommandBuffer scriptableRenderContext.ExecuteCommandBuffer(myCommandBuffer); myCommandBuffer.Clear();

// Schedule the drawing operation scriptableRenderContext.DrawRenderers(exampleCullingResults, ref exampleDrawingSettings, ref exampleFilteringSettings);

// Perform all scheduled tasks, in the order that they were scheduled // This means that the CommandBuffer is executed before the drawing operation occurs scriptableRenderContext.Submit(); } }

Overriding the render state

When you draw geometry using this function, you can use one or more RenderStateBlock structs to override the GPU's render state in the following ways: You can use the stateBlock parameter to provide a single RenderStateBlock struct. Unity uses the render state defined in stateBlock for all the geometry that this function draws. You can use the stateBlocks parameter to provide an array of RenderStateBlock structs, and the renderTypes parameter to provide an array of values for the SubShader Tag with a name of RenderType. For each element in the renderTypes array, if Unity finds geometry with a SubShader Tag name of RenderType and a matching value, it uses the render state defined in the corresponding element of the stateBlocks array. If there are multiple matches, Unity uses the first one. If an element in the renderTypes array has the default value for ShaderTagId, Unity treats this as a catch-all and uses the corresponding render state for all geometry. You can use the stateBlocks parameter to provide an array of RenderStateBlock structs, and use the tagName, tagValues, and isPassTagName parameters to specify the name and values of any SubShader Tag or Pass Tag. For each element in the tagNames and tagValues arrays, Unity identifies geometry with a matching SubShader Tag or Pass Tag name and value, and applies the render state defined in the corresponding element of the stateBlocks array. If there are multiple matches, Unity uses the first one. If an element in the tagValues has the default value for ShaderTagId, Unity treats this as a catch-all and uses the corresponding render state for all geometry. This example demonstrates how to override the render state:

using UnityEngine;
using UnityEngine.Rendering;
using Unity.Collections;

public class OverrideRenderStateExample { ScriptableRenderContext scriptableRenderContext;

// Placeholder data DrawingSettings exampleDrawingSettings; CullingResults exampleCullingResults = new CullingResults(); FilteringSettings exampleFilteringSettings = new FilteringSettings();

// Override the render state for all geometry that this function draws public void OverrideRenderStateForAll() { // Tell Unity how to override the render state var stateBlock = new RenderStateBlock(RenderStateMask.Depth); stateBlock.depthState = new DepthState(true, CompareFunction.LessEqual);

// Schedule a command to draw the geometry using the desired render state // Unity will execute all scheduled commands during the next call to ScriptableRenderContext.Submit scriptableRenderContext.DrawRenderers(exampleCullingResults, ref exampleDrawingSettings, ref exampleFilteringSettings, ref stateBlock); }

// Override the render state for all geometry that has a SubShader Tag // with a name of "RenderType" and a value of "ExampleRenderTypeTagValue" public void OverrideRenderStateUsingRenderTypeTag() { // Create the parameters that tell Unity how to override the render state var stateBlock = new RenderStateBlock(RenderStateMask.Depth); stateBlock.depthState = new DepthState(true, CompareFunction.Greater); var stateBlocks = new NativeArray<RenderStateBlock>(1, Allocator.Temp); stateBlocks[0] = stateBlock;

// Create the parameters that tell Unity when to override the render state ShaderTagId renderType = new ShaderTagId("ExampleRenderTypeTagValue"); var renderTypes = new NativeArray<ShaderTagId>(1, Allocator.Temp); renderTypes[0] = renderType;

// Schedule a command to draw the geometry using the desired render state // Unity will execute all scheduled commands during the next call to ScriptableRenderContext.Submit scriptableRenderContext.DrawRenderers(exampleCullingResults, ref exampleDrawingSettings, ref exampleFilteringSettings, renderTypes, stateBlocks);

// DrawRenderers copies the array contents, so it is safe to dispose of the native arrays stateBlocks.Dispose(); renderTypes.Dispose(); }

// Override the render state in two different ways. // Use one state for all geometry that has a Pass Tag // with a name of "ExamplePassTagName" and a value of "ExamplePassTagValue". // For all other geometry, use a second state. public void OverrideRenderStateUsingPassTag() { // Create the parameters that tell Unity how to override the render state var stateBlock0 = new RenderStateBlock(RenderStateMask.Depth); stateBlock0.depthState = new DepthState(true, CompareFunction.Greater); var stateBlock1 = new RenderStateBlock(RenderStateMask.Depth); stateBlock1.depthState = new DepthState(true, CompareFunction.Less); var stateBlocks = new NativeArray<RenderStateBlock>(2, Allocator.Temp); stateBlocks[0] = stateBlock0; stateBlocks[1] = stateBlock1; // default override

// Create the parameters that tell Unity when to override the render state ShaderTagId tagName = new ShaderTagId("ExamplePassTagName"); bool isPassTagName = true; var tagValues = new NativeArray<ShaderTagId>(2, Allocator.Temp); tagValues[0] = new ShaderTagId("ExamplePassTagValue"); tagValues[1] = new ShaderTagId(); // catch all

// Schedule a command to draw the geometry using the desired render state // Unity will execute all scheduled commands during the next call to ScriptableRenderContext.Submit scriptableRenderContext.DrawRenderers(exampleCullingResults, ref exampleDrawingSettings, ref exampleFilteringSettings, tagName, isPassTagName, tagValues, stateBlocks);

// DrawRenderers copies the array contents, so it is safe to dispose of the native arrays stateBlocks.Dispose(); tagValues.Dispose(); } }
