Properties

AutoCoverCompleteScene

Gets or sets a value indicating whether shadow map should automatically cover complete scene. Only effective with directional light.

Limitation: Currently unable to properly cover BoneSkinned model animation.

public bool AutoCoverCompleteScene { get; set; }

Property Value

bool

true if [automatic cover complete scene]; otherwise, false.

Bias 

public float Bias { get; set; }

Property Value

float

CastSceneScale

Gets or sets the shadow cast scene scale. Only effective if AutoCoverCompleteScene is true.

This is used if the mesh render shadow is much bigger than the meshes casting shadow. The shadow cast camera has to cover the shadow rendering region, otherwise the shadow maybe cut off. Increase the value to increase the shadow cast camera rendering region. 

public float CastSceneScale { get; set; }

Property Value

float

Region scale for shadow cast.

Distance 

public float Distance { get; set; }

Property Value

float

FarField

Gets or sets the far field.

public float FarField { get; set; }

Property Value

float

The far field.

Intensity 

public float Intensity { get; set; }

Property Value

float

IsSceneDynamic

Gets or sets a value indicating whether the scene is dynamic. Only effective if AutoCoverCompleteScene is true.

Setting to true will force shadow map to update the shadow camera for each frame. May impact the performance.

public bool IsSceneDynamic { get; set; }

Property Value

bool

true if scene is dynamic; otherwise, false.

LightCamera

Distance of the directional light from origin

public ProjectionCameraCore? LightCamera { get; set; }

Property Value

ProjectionCameraCore

NearField

Gets or sets the near field.

public float NearField { get; set; }

Property Value

float

The far field.

OrthoWidth 

public float OrthoWidth { get; set; }

Property Value

float

Resolution

Gets or sets the resolution.

public Size2 Resolution { get; set; }

Property Value

Size2

The resolution.
