Documentation

Description

MFnNonAmbientLight facilitates modification of dependency graph nodes representing non-ambient lights. This includes area lights, linear lights, and non-extended lights.

Functions

MFnNonAmbientLight:: MFnNonAmbientLight ()

Description

Default class constructor. The function set is not attached to an MObject.

MFnNonAmbientLight:: MFnNonAmbientLight ( MObject & object, MStatus * ReturnStatus )

Description

Class constructor that initializes the function set to the given MObject.

Arguments

• object the MObject to attach the function set to
• ReturnStatus the return status
  • MS::kSuccess if the function set is successfully attached
  • MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFnNonAmbientLight:: MFnNonAmbientLight ( const MObject & object, MStatus * ReturnStatus )

Description

Class constructor that initializes the function set to the given constant MObject.

Arguments

• object the const MObject to attach the function set to
• ReturnStatus the return status
  • MS::kSuccess if the function set is successfully attached
  • MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFnNonAmbientLight:: MFnNonAmbientLight ( const MDagPath & object, MStatus * ReturnStatus )

Description

Class constructor that initializes the function set to the given constant MDagPath object.

Arguments

• object the const MDagPath to attach the function set to
• ReturnStatus the return status
  • MS::kSuccess if the function set is successfully attached
  • MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFn::Type MFnNonAmbientLight:: type () const

Description

Return the type of this function set.

Return Value

• the constant MFn::kNonAmbientLight

MFnNonAmbientLight:: ~MFnNonAmbientLight ()

Description

The class destructor.

short MFnNonAmbientLight:: decayRate ( MStatus * ReturnStatus ) const

Description

Retrieves the value of the "decayRate" attribute of a non-ambient light node. This attribute determines the type of decay for the light.

The decay rate is with respect to the distance between the light and the surface point being shaded. The decay values range from 0 - 3. The light intensity decays according to (I / d ** v), where I is the light intensity, d is the distance between the light and the surface point being shaded, and v is the decay rate value. A decay rate of 0 means there is no decay in intensity, a value of 1 indicates linear decay. A decay rate of 2 is the most physically accurate behaviour.

Arguments

• ReturnStatus return status

Return Value

• The value of the "decayRate" attribute of the non-ambient light node.

Status Codes

• MS::kSuccess operation successful
• MS::kFailure function set doesn not have a valid object.

MStatus MFnNonAmbientLight:: setDecayRate ( const short& decay_rate )

Description

Sets the value of the "decayRate" attribute of a non-ambient light node.

Arguments

• decay_rate value to which the attribute will be set.

Return Value

• return status

Status Codes

• MS::kSuccess operation successful
• MS::kFailure function set doesn not have a valid object,
