Constructor & Destructor Documentation

MPlane ( )

Class default constructor.

Create a new default plane.

MPlane ( const MPlane & src )

Class copy constructor.

Create a new vector and initialize it to the same values as the given plane.

Parameters:

[in] src the plane to copy

MVector normal ( ) const

Returns the normal of the plane.

double distance ( ) const

Returns the distance of the plane along the normal.

Directly set the equation of the plane in the form: ax + by +cz + d = 0.

Parameters:

[in]	a	The plane equation's x coefficent
[in]	b	The plane equation's y coefficent
[in]	c	The plane equation's z coefficent
[in]	d	The plane equation's constant distance term
