Detailed Description

The class used to compute vertex normals considering smoothing.

Constructor & Destructor Documentation

VertexNormal() [1/3]

VertexNormal

(

)

Default Constructor.

VertexNormal() [2/3]

VertexNormal	(	Point3 &	n,
		DWORD	s
	)

Constructor.

Parameters

n	- The vertex normal vector
s	- The ID of the smoothing group

VertexNormal() [3/3]

VertexNormal

(

const VertexNormal &

copyVNormal

)

Copy Constructor.

~VertexNormal()

virtual ~VertexNormal ( )

virtual

Destructor.

Member Function Documentation

operator=()

VertexNormal& operator=

(

const VertexNormal &

from

)

Assignment operator.

AddNormal()

void AddNormal	(	Point3 &	n,
		DWORD	s
	)

Add a normal to the list if the smoothing group bits overlap, otherwise create a new vertex normal in the list.

It is used when a face is going to add its normal to a vertex. This method is passed the normal and the smoothing information for that face. It checks if the normal passed shares smoothing information with the existing normal. If it does, the normal is added in, and the smoothing bits are bitwise OR-ed in. If it does not, a new vertex normal is created.

Parameters

n	The new normal to be added.
s	The smoothing group information.

GetNormal()

Point3& GetNormal

(

DWORD

s

)

Retrieves a normal if the smoothing groups overlap or there is only one in the list.

Parameters

s	The smoothing group information.

Returns

The Normal

Normalize()

void Normalize

(

)

Normalize each normal in the list.

Member Data Documentation

norm

Point3 norm

The normal.

smooth

DWORD smooth

The smoothing groups.

next

VertexNormal* next

A pointer to the next normal – this class is a linked list.

init

BOOL init

The init variable is used as a flag to indicate if the first normal in the list has been initialized.
