Light
Overview
Light is a class in Aspose.3D FOSS for .NET.
Inherits from: Frustum, INamedObject, IOrientable.
The light illuminates the scene.
This class provides 15 methods for working with Light objects in .NET programs.
Available methods include: A3DObject, Entity, FindProperty, GetBoundingBox, GetEntityRendererKey, GetProperty, Light, RemoveProperty, SceneObject, SetProperty.
All public members are accessible to any .NET application after installing the Aspose.3D FOSS for .NET package.
Properties: Aspect, CastLight, CastShadows, Color, ConstantAttenuation, Direction, and 20 more.

| Name | Type | Access | Description |
|---|---|---|---|
Color | Vector3 | Read/Write | Gets or sets the light’s color |
LightType | LightType | Read/Write | Gets or sets the light’s type |
CastLight | bool | Read/Write | Gets or sets if the current light instance can illuminate other objects. |
Intensity | double | Read/Write | Gets or sets the light’s intensity, default value is 100 |
HotSpot | double | Read/Write | Gets or sets the hot spot cone angle(in degrees). |
Falloff | double | Read/Write | Gets or sets the falloff cone angle (in degrees). |
ConstantAttenuation | double | Read/Write | Gets or sets the constant attenuation to calculate the total attenuation of the light |
LinearAttenuation | double | Read/Write | Gets or sets the linear attenuation to calculate the total attenuation of the light |
QuadraticAttenuation | double | Read/Write | Gets or sets the quadratic attenuation to calculate the total attenuation of the light |
CastShadows | bool | Read/Write | Gets or sets if the light can cast shadows on other objects. |
ShadowColor | Vector3 | Read/Write | Gets or sets the shadow’s color. |
RotationMode | RotationMode | Read/Write | Gets or sets the frustum’s orientation mode This property only works when the Target is null. |
NearPlane | double | Read/Write | Gets or sets the frustum’s near plane distance. |
FarPlane | double | Read/Write | Gets or sets the frustum’s far plane distance. |
Aspect | double | Read/Write | Gets or sets the aspect ratio of the frustum |
OrthoHeight | double | Read/Write | Gets or sets the height when frustum in orthographic projection. |
Up | Vector3 | Read/Write | Gets or sets the up direction of the camera |

Target | Node | Read/Write | Gets or sets the target that the camera is looking at. |
Excluded | bool | Read/Write | Gets or sets whether to exclude this entity during exporting. |
ParentNodes | List<Node> | Read | Gets all parent nodes, an entity can be attached to multiple parent nodes for geometry instancing |
ParentNode | Node | Read/Write | Gets or sets the first parent node, if set the first parent node, this entity will be detached from other parent nodes. |
Scene | Scene | Read | Gets the scene that this object belongs to |
Name | string | Read/Write | Gets or sets the name. |
Properties | PropertyCollection | Read | Gets the collection of all properties. |
