|
inline |
Copy constructor using CopyOp to manage deep vs shallow copy.
|
protectedvirtual |
Apply the light's state to the OpenGL state machine.
Reimplemented from osg::StateAttribute.
void osg::Light::captureLightState | ( | ) |
Capture the lighting settings of the current OpenGL state and store them in this object.
|
inlinevirtual |
Return the name of the attribute's class type.
Reimplemented from osg::StateAttribute.
|
inlinevirtual |
Clone an attribute, with Object* return type. Must be defined by derived classes.
Implements osg::StateAttribute.
