Syntax

public class DirectionalLightShader : SharedDXDeviceResource, 
	IStandardShader

The DirectionalLightShader type exposes the following members.

Constructors

	Name	Description
	DirectionalLightShader	Initializes a new instance of the DirectionalLightShader class

Methods

	Name	Description
	ApplyMaterial	Sets the content of the constant buffers based on the specified Material and other properties.
	ApplyPerFrameSettings	Sets per frame settings for this effect (this sets camera, lights and other per frame settings).
	PreloadShaders	Loads all the shaders
	ResetRenderableGeometryMaterialFlagsValue	When RenderableGeometry objects are rendered in the same order in each frame, the RenderableGeometry.MaterialFlags value specifies how similar the material is to the previous object (for example if diffuse part is the same, then many color checks can be skipped). But when the order of rendering is changed or if we start rendering from the middle of the RenderingQueue, then we need to reset the cached value for the first rendered RenderableGeometry so that all the checks are done agine. This method does that.
	SetCustomPerFrameConstantBuffers	SetCustomPerFrameConstantBuffers sets custom perFrameCameraConstantsBuffer and perFrameLightsConstantBuffer. Note that the constant buffers need to be exactly the same as the DirectionalLightShader expects.
