You can use the Q3Light_GetType function to get the type of a light object.

TQ3ObjectType Q3Light_GetType (TQ3LightObject light);

A light object.

DESCRIPTION

The Q3Light_GetType function returns, as its function result, the type of the light object specified by the light parameter. The types of light objects currently supported by QuickDraw 3D are defined by these constants:

kQ3LightTypeAmbient
kQ3LightTypeDirectional
kQ3LightTypePoint
kQ3LightTypeSpot

If the specified light object is invalid or is not one of these types, Q3Light_GetType returns the value kQ3ObjectTypeInvalid.
