MNMapFace Class Reference

#include <mnmesh.h>

Class Description

Used to store map vertex information for a given face and map channel.

By way of analogy: MNMapFace is to MNFace as TVFace is to Face. MNMapFace is to MNMap as MNFace is to MNMesh as TVFace is to MeshMap as Face is to Mesh.

Constructor & Destructor Documentation

MNMapFace ( )

inline

Constructor.

Calls Init().

{ Init(); }

DllExport MNMapFace

(

int

d

)

Constructor.

Sets the degree and hidden vertex count.

Parameters:

int d

Desired degree.

~MNMapFace ( )

inline

Destructor.

Calls Clear().

{ Clear(); }

Member Function Documentation

DllExport void Init

(

)

Initializes MNMapFace.

deg is set to 0, pointers set to NULL.

DllExport void Clear

(

)

Clears and frees MNMapFace.

DllExport void SetAlloc

(

int

d

)

Allocates enough memory in the arrays for the face to have degree d, but does not actually set the degree.

If the arrays are already large enough (or larger), it does not reallocate them.

Parameters:

int d

The degree for this map face.

void SetSize ( int  d )

inline

Allocates enough memory in the arrays for the face to have degree d, and then sets the degree.

If the arrays are already large enough (or larger), it does not reallocate them. You generally don't need to use this method separately; MakePoly, Insert, and other methods which may require additional memory will call this if needed.

{ SetAlloc(d); deg=d; }

DllExport void MakePoly	(	int	fdeg,
		int *	tt
	)

Makes this face into a polygon with the specified vertices and other information.

Parameters:

int fdeg

The degree to set this face to.

int *tt

The list of vertices for this face.

DllExport void Insert	(	int	pos,
		int	num = 1
	)

Inserts space for more vertices at the specified position.

Parameters:

int pos

The location within the map face where the new vertices should be added.

int num=1

The number of new vertices to add.

DllExport void Delete	(	int	pos,
		int	num = 1
	)

Deletes vertices from this map face.

Parameters:

The location within the map face where the vertices should be deleted.

int num=1

The number of vertices to delete.

DllExport void RotateStart

(

int

newstart

)

Re-indexes the vertices and edges so that the vertex in position newstart becomes the new first vertex.

Triangulation is also corrected.

Parameters:

int newstart

The new first vertex.

DllExport void Flip

(

)

Reverses order of verts, effectively inverting the face.

DllExport int VertIndex

(

int

vv

)

Returns the position of vertex vv in this face's list of vertices.

Parameters:

int vv

The vertex whose index is returned.

DllExport void ReplaceVert	(	int	ov,
		int	nv
	)

Replaces vertex ov with vertex nv in the list of vertices.

Parameters:

int ov

The vertex to replace.

int nv

The vertex to replace it with.

DllExport MNMapFace& operator=

(

const MNMapFace &

from

)

Assignment operator.

DllExport MNMapFace& operator=

(

const MNFace &

from

)

Assignment operator.

DllExport bool operator==

(

const MNMapFace &

from

)

Assignment operator.

DllExport void MNDebugPrint

(

)

Debug print statement.
