Detailed Description

Billboard node instances.

Constructor.

Parameters:

nodeType	the NodeType associated with the node instance.
scope	the Scope to which the node belongs.

~Billboard ( ) throw () [virtual]

Destructor.

void accumulateTransform ( Node * parent ) [virtual]

Cache a pointer to (one of the) parent transforms for proper rendering of bindables.

Reimplemented from Group.

Calculate bb transformation matrix and store it in M.

Here we are dealing with VrmlMatrix format (Matrices are stored in row-major order).

Parameters:

t_arg	a pointer to a Billboard node.
L_MV	input ModelView transformation matrix.

Return values:

M	a copy of the resulting transform.

void processSet_axisOfRotation	(	const FieldValue &	sfvec3f,
		double	timestamp
	)	throw (std::bad_cast) `[private]`

set_axisOfRotation eventIn handler.

Parameters:

sfvec3f	an SFVec3f.
timestamp	the current time.

Exceptions:

std::bad_cast if sfvec3f is not an SFVec3f.

Render the node.

Parameters:

viewer	a Viewer.
context	the rendering context.

Reimplemented from Group.
