Light Properties

Gets or sets the ambient color.

Get the type of attenuation for this light.

Gets or Sets the attenuation vector.

Gets a value, determined by LightStyle, that explains whether the camera directions are relative to World or Camera spaces.

Gets or sets the diffuse color.

Gets or sets the vector direction of the camera.

Indicates if this object has been disposed or the document it originally belonged to has been disposed.

Returns true if the Brep.TryConvertBrep function will be successful for this object

Gets true if this class has any custom information attached to it through UserData.

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.

Gets the ID of this light.

Gets or sets the light intensity.

true if object can be accurately modified with "squishy" transformations like projections, shears, and non-uniform scaling.

Gets a value indicating whether the light style is LightStyle CameraDirectional or WorldDirectional.

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.

Gets or sets a value that defines if the light is turned on (true) or off (false).

Gets a value indicating whether the light style is LightStyle WorldLinear.

Gets a value indicating whether the light style is LightStyle CameraPoint or WorldPoint.

Gets a value indicating whether the light style is LightStyle WorldRectangular.

Gets a value indicating whether the light style is LightStyle CameraSpot or WorldSpot.

Gets a value indicating whether this object is a Sun light.

Tests an object to see if it is valid.

Gets or sets the height in linear and rectangular lights.

(ignored for non-linear/rectangular lights.)

Gets or sets a light style on this camera.

Gets or sets the light or 3D position or location.

Gets or sets the light name.

Useful for switch statements that need to differentiate between basic object types like points, curves, surfaces, and so on.

Gets a perpendicular vector to the camera direction.

Gets or sets the light power in candelas (cd).

Gets or sets the light power in lumens (lm).

Gets or sets the light power in watts (W).

Gets or sets the shadow intensity for the light.

Gets or sets the specular color.

Gets or sets the spot angle in radians.

Ignored for non-spot lights.

angle = 0 to pi/2 (0 to 90 degrees).

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.

Gets or sets the spot light shadow intensity.

(ignored for non-spot lights.)

List of custom information that is attached to this class.

Dictionary of custom information attached to this class. The dictionary is actually user data provided as an easy to use shareable set of information.

Gets the amount of user strings.

Gets or sets the width in linear and rectangular lights.

(ignored for non-linear/rectangular lights.)
