Member Function Documentation

const af_node_instance* POLYGON_VERTEX::data

(

)

[inline]

Returns the data.

void POLYGON_VERTEX::destroy

(

VERTEX_TEMPLATE *

node_template

)

Destroys itself.

Parameters:

node_template

vertex template - node template.

logical POLYGON_VERTEX::get_parameter_data	(	VERTEX_TEMPLATE *	vertemp,
		parameter_token	partok,
		double *	nodedata
	)

Gets the parameter data of the node and returns it in the array.

Parameters:

	vertemp	vertex template.
	partok	parameter token.
	nodedata	node data cell type.

POLYGON_VERTEX* POLYGON_VERTEX::next

(

)

Returns a pointer to the next vertex in a polygon.

logical POLYGON_VERTEX::normal	(	VERTEX_TEMPLATE *	vertemp,
		SPAunit_vector &	uv
	)

Returns the normal of the vertex.

Role: If the return value is FALSE, the method could not determine the normal.

Parameters:

	vertemp	vertex template.
	uv	normal.

logical POLYGON_VERTEX::point

(

SPAposition &

pt

)

Returns the position of the vertex.

Role: If the return value is FALSE, the method could not determine the position.

Parameters:

pt

point.

void POLYGON_VERTEX::print	(	VERTEX_TEMPLATE *	vt = 0,
		FILE *	to = stderr
	)

Prints the polygon vertex.

Parameters:

	vt	vertex template.
	to	file to print to.

void POLYGON_VERTEX::set_normal	(	VERTEX_TEMPLATE *	vertemp,
		const SPAunit_vector &	uv
	)

Sets the normal of the vertex.

Parameters:

	vertemp	vertex template.
	uv	normal.

void POLYGON_VERTEX::set_parameter_data	(	VERTEX_TEMPLATE *	vertemp,
		parameter_token	partok,
		double *	nodedata
	)

Sets the parameter data as specified in the array.

Parameters:

	vertemp	vertex template.
	partok	parameter token.
	nodedata	node data cell type.

void POLYGON_VERTEX::set_point

(

const SPAposition &

pt

)

Sets the position of the vertex.

Parameters:

pt

point.
