Methods

CreateCameraMaterial(string)

Create the camera material from the given camera shader name.

Declaration

protected Material CreateCameraMaterial(string cameraShaderName)

Parameters

Type	Name	Description
string	cameraShaderName	The name of the camera shader.

Returns

Type	Description
Material	The created camera material shader.

Exceptions

Type	Condition
InvalidOperationException	Thrown if the shader cannot be found or if a material cannot be created for the shader.

Destroy()

Destroy the camera for the subsystem.

Declaration

public override void Destroy()

Overrides

UnityEngine.SubsystemsImplementation.SubsystemProvider<UnityEngine.XR.ARSubsystems.XRCameraSubsystem>.Destroy()

GetConfigurations(XRCameraConfiguration, Allocator)

Get the supported camera configurations.

Declaration

public virtual NativeArray<XRCameraConfiguration> GetConfigurations(XRCameraConfiguration defaultCameraConfiguration, Allocator allocator)

Parameters

Type	Name	Description
XRCameraConfiguration	defaultCameraConfiguration	A default value used to fill the returned array before copying in real values. This ensures future additions to this struct are backwards compatible.
Allocator	allocator	The allocation strategy to use for the returned data.

Returns

Type	Description
NativeArray<XRCameraConfiguration>	The supported camera configurations.

GetMaterialKeywords(out List<string>, out List<string>)

Get the enabled and disabled shader keywords for the Material.

Declaration
