Light Properties |
The Light type exposes the following members.
Name | Description | |
---|---|---|
![]() | Ambient |
Gets or sets the ambient color.
|
![]() | AttenuationType |
Get the type of attenuation for this light.
|
![]() | AttenuationVector |
Gets or Sets the attenuation vector.
|
![]() | CoordinateSystem |
Gets a value, determined by LightStyle, that explains whether
the camera directions are relative to World or Camera spaces.
|
![]() ![]() | Diffuse |
Gets or sets the diffuse color.
|
![]() | Direction |
Gets or sets the vector direction of the camera.
|
![]() | Disposed |
Indicates if this object has been disposed or the
document it originally belonged to has been disposed.
(Inherited from CommonObject.) |
![]() | HasBrepForm |
Returns true if the Brep.TryConvertBrep function will be successful for this object
(Inherited from GeometryBase.) |
![]() | HasUserData |
Gets true if this class has any custom information attached to it through UserData.
(Inherited from CommonObject.) |
![]() | HotSpot |
The hot spot setting runs from 0.0 to 1.0 and is used to
provides a linear interface for controlling the focus or
concentration of a spotlight.
A hot spot setting of 0.0 corresponds to a spot exponent of 128.
A hot spot setting of 1.0 corresponds to a spot exponent of 0.0.
|
![]() | Id | Gets the ID of this light. |
![]() | Intensity |
Gets or sets the light intensity.
|
![]() | IsDeformable |
true if object can be accurately modified with "squishy" transformations like
projections, shears, and non-uniform scaling.
(Inherited from GeometryBase.) |
![]() | IsDirectionalLight |
Gets a value indicating whether the light style
is LightStyle CameraDirectional or WorldDirectional.
|
![]() | IsDocumentControlled |
If true this object may not be modified. Any properties or functions that attempt
to modify this object when it is set to "IsReadOnly" will throw a NotSupportedException.
(Inherited from GeometryBase.) |
![]() | IsEnabled |
Gets or sets a value that defines if the light is turned on (true) or off (false).
|
![]() | IsLinearLight |
Gets a value indicating whether the light style
is LightStyle WorldLinear.
|
![]() | IsPointLight |
Gets a value indicating whether the light style
is LightStyle CameraPoint or WorldPoint.
|
![]() | IsRectangularLight |
Gets a value indicating whether the light style
is LightStyle WorldRectangular.
|
![]() | IsSpotLight |
Gets a value indicating whether the light style
is LightStyle CameraSpot or WorldSpot.
|
![]() | IsSunLight |
Gets a value indicating whether this object is a Sun light.
|
![]() | IsValid | Tests an object to see if it is valid. (Inherited from CommonObject.) |
![]() | Length |
Gets or sets the height in linear and rectangular lights.
(ignored for non-linear/rectangular lights.) |
![]() | LightStyle |
Gets or sets a light style on this camera.
|
![]() | Location |
Gets or sets the light or 3D position or location.
|
![]() | Name |
Gets or sets the spot light name.
|
![]() | ObjectType |
Useful for switch statements that need to differentiate between
basic object types like points, curves, surfaces, and so on.
(Inherited from GeometryBase.) |
![]() | PerpendicularDirection |
Gets a perpendicular vector to the camera direction.
|
![]() | PowerCandela |
Gets or sets the light power in candelas (cd).
|
![]() | PowerLumens |
Gets or sets the light power in lumens (lm).
|
![]() | PowerWatts |
Gets or sets the light power in watts (W).
|
![]() | ShadowIntensity |
Gets or sets the shadow intensity for the light.
|
![]() | Specular |
Gets or sets the specular color.
|
![]() | SpotAngleRadians |
Gets or sets the spot angle in radians.
Ignored for non-spot lights. angle = 0 to pi/2 (0 to 90 degrees). |
![]() | SpotExponent |
The spot exponent varies from 0.0 to 128.0 and provides
an exponential interface for controlling the focus or
concentration of a spotlight (like the
OpenGL GL_SPOT_EXPONENT parameter). The spot exponent
and hot spot parameters are linked; changing one will
change the other.
A hot spot setting of 0.0 corresponds to a spot exponent of 128.
A hot spot setting of 1.0 corresponds to a spot exponent of 0.0.
|
![]() | SpotLightShadowIntensity | Obsolete.
Gets or sets the spot light shadow intensity.
(ignored for non-spot lights.) |
![]() | UserData |
List of custom information that is attached to this class.
(Inherited from CommonObject.) |
![]() | UserDictionary |
Dictionary of custom information attached to this class. The dictionary is actually user
data provided as an easy to use shareable set of information.
(Inherited from CommonObject.) |
![]() | UserStringCount |
Gets the amount of user strings.
(Inherited from GeometryBase.) |
![]() | Width |
Gets or sets the width in linear and rectangular lights.
(ignored for non-linear/rectangular lights.) |
