Member Function Documentation

virtual void osg::AutoTransform::accept

(

NodeVisitor &

nv

)

[virtual]

Visitor Pattern : calls the apply method of a NodeVisitor with this node's type.

Reimplemented from osg::Node.

virtual const AutoTransform* osg::AutoTransform::asAutoTransform

(

)

const [inline, virtual]

virtual AutoTransform* osg::AutoTransform::asAutoTransform

(

)

[inline, virtual]

virtual const char* osg::AutoTransform::className

(

)

const [inline, virtual]

return the name of the node's class type.

Reimplemented from osg::Node.

virtual osg::Object* osg::AutoTransform::clone

(

const osg::CopyOp &

copyop

)

const [inline, virtual]

return a clone of a node, with Object* return type.

Reimplemented from osg::Node.

virtual osg::Object* osg::AutoTransform::cloneType

(

)

const [inline, virtual]

clone an object of the same type as the node.

Reimplemented from osg::Node.

virtual BoundingSphere osg::AutoTransform::computeBound

(

)

const [virtual]

Overrides Group's computeBound. There is no need to override in subclasses from osg::Transform since this computeBound() uses the underlying matrix (calling computeMatrix if required).

Reimplemented from osg::Transform.

virtual bool osg::AutoTransform::computeLocalToWorldMatrix	(	Matrix &	matrix,
		NodeVisitor *	nv
	)			const [virtual]

Reimplemented from osg::Transform.

void osg::AutoTransform::computeMatrix

(

)

const [protected]

virtual bool osg::AutoTransform::computeWorldToLocalMatrix	(	Matrix &	matrix,
		NodeVisitor *	nv
	)			const [virtual]

Reimplemented from osg::Transform.
