Class ScriptableRenderer

Class ScriptableRenderer implements a rendering strategy. It describes how culling and lighting works and the effects supported.

TODO RENDERGRAPH: UPDATE THIS DOC FOR THE RENDERGRAPH PATH A renderer can be used for all cameras or be overridden on a per-camera basis. It will implement light culling and setup and describe a list of ScriptableRenderPass to execute in a frame. The renderer can be extended to support more effect with additional ScriptableRendererFeature. Resources for the renderer are serialized in ScriptableRendererData.

The renderer resources are serialized in ScriptableRendererData. ScriptableRendererData ScriptableRendererFeature ScriptableRenderPass

Methods

Dispose()

Disposable pattern implementation. Cleans up resources used by the renderer.

Declaration

public void Dispose()

Dispose(bool)

Called by Dispose(). Override this function to clean up resources in your renderer. Be sure to call this base dispose in your overridden function to free resources allocated by the base.

Declaration

protected virtual void Dispose(bool disposing)

Parameters

Type	Name	Description
bool	disposing

EnqueuePass(ScriptableRenderPass)

Enqueues a render pass for execution.

Declaration

public void EnqueuePass(ScriptableRenderPass pass)

Parameters

Type	Name	Description
ScriptableRenderPass	pass	Render pass to be enqueued.

FinishRendering(CommandBuffer)

Called upon finishing rendering the camera stack. You can release any resources created by the renderer here.

Declaration

public virtual void FinishRendering(CommandBuffer cmd)

Parameters

Type	Name	Description
CommandBuffer	cmd

GetCameraClearFlag(ref CameraData)

Returns a clear flag based on CameraClearFlags.

Declaration

protected static ClearFlag GetCameraClearFlag(ref CameraData cameraData)

Parameters

Type	Name	Description
CameraData	cameraData	The Camera data.

Returns

Type	Description
ClearFlag	A clear flag that tells if color and/or depth should be cleared.

See Also

CameraData

GetCameraClearFlag(UniversalCameraData)

Returns a clear flag based on CameraClearFlags.

Declaration

protected static ClearFlag GetCameraClearFlag(UniversalCameraData cameraData)

Parameters

Type	Name	Description
UniversalCameraData	cameraData	The Camera data.

Returns

Type	Description
ClearFlag	A clear flag that tells if color and/or depth should be cleared.

CameraData

OnBeginRenderGraphFrame()

Override this method to initialize before recording the render graph, such as resources.

Declaration

public virtual void OnBeginRenderGraphFrame()

OnEndRenderGraphFrame()

Override this method to cleanup things after recording the render graph, such as resources.

Declaration

public virtual void OnEndRenderGraphFrame()

SetCameraMatrices(CommandBuffer, ref CameraData, bool)

Set camera matrices. This method will set UNITY_MATRIX_V, UNITY_MATRIX_P, UNITY_MATRIX_VP to camera matrices. Additionally this will also set unity_CameraProjection and unity_CameraProjection. If setInverseMatrices is set to true this function will also set UNITY_MATRIX_I_V and UNITY_MATRIX_I_VP. This function has no effect when rendering in stereo. When in stereo rendering you cannot override camera matrices. If you need to set general purpose view and projection matrices call SetViewAndProjectionMatrices(CommandBuffer, Matrix4x4, Matrix4x4, bool) instead.

Declaration

public static void SetCameraMatrices(CommandBuffer cmd, ref CameraData cameraData, bool setInverseMatrices)

Parameters

Type	Name	Description
CommandBuffer	cmd	CommandBuffer to submit data to GPU.
CameraData	cameraData	CameraData containing camera matrices information.
bool	setInverseMatrices	Set this to true if you also need to set inverse camera matrices.

SetCameraMatrices(CommandBuffer, UniversalCameraData, bool)

Set camera matrices. This method will set UNITY_MATRIX_V, UNITY_MATRIX_P, UNITY_MATRIX_VP to camera matrices. Additionally this will also set unity_CameraProjection and unity_CameraProjection. If setInverseMatrices is set to true this function will also set UNITY_MATRIX_I_V and UNITY_MATRIX_I_VP. This function has no effect when rendering in stereo. When in stereo rendering you cannot override camera matrices. If you need to set general purpose view and projection matrices call SetViewAndProjectionMatrices(CommandBuffer, Matrix4x4, Matrix4x4, bool) instead.

Declaration

public static void SetCameraMatrices(CommandBuffer cmd, UniversalCameraData cameraData, bool setInverseMatrices)

Parameters

Type	Name	Description
CommandBuffer	cmd	CommandBuffer to submit data to GPU.
UniversalCameraData	cameraData	CameraData containing camera matrices information.
bool	setInverseMatrices	Set this to true if you also need to set inverse camera matrices.

SetupCullingParameters(ref ScriptableCullingParameters, ref CameraData)

Override this method to configure the culling parameters for the renderer. You can use this to configure if lights should be culled per-object or the maximum shadow distance for example.

Declaration

public virtual void SetupCullingParameters(ref ScriptableCullingParameters cullingParameters, ref CameraData cameraData)

Parameters

Type	Name	Description
ScriptableCullingParameters	cullingParameters	Use this to change culling parameters used by the render pipeline.
CameraData	cameraData	Current render state information.

SupportedCameraStackingTypes()

This setting controls if the camera editor should display the camera stack category. If your renderer is not supporting stacking this one should return 0. For the UI to show the Camera Stack widget this must support CameraRenderType.Base. CameraRenderType

Declaration

public virtual int SupportedCameraStackingTypes()

Returns

Type	Description
int	The bitmask of the supported camera render types in the renderer's current state.

SupportsCameraStackingType(CameraRenderType)

Check if the given camera render type is supported in the renderer's current state.

Declaration

public bool SupportsCameraStackingType(CameraRenderType cameraRenderType)

Parameters

Type	Name	Description
CameraRenderType	cameraRenderType	The camera render type that is checked if supported.

Returns

Type	Description
bool	True if the given camera render type is supported in the renderer's current state.

SupportsMotionVectors()

Check if the ScriptableRenderer implements a motion vector pass for temporal techniques. The Camera will check this to enable/disable features and/or apply jitter when required.

For example, Temporal Anti-aliasing in the Camera settings is enabled only if the ScriptableRenderer can support motion vectors.

Declaration

protected virtual bool SupportsMotionVectors()

Returns

Type	Description
bool	Returns true if the ScriptableRenderer implements a motion vector pass. False otherwise.
