Description:

The manipulator system exports a helper plane class. This is very useful when writing OnMouseMove() methods. It is normally used to intersect a view ray with some plane that is used by the manipulator.

Data Members:

static Plane msXYPlane;

This constant defines the XY plane.

Constructor & Destructor Documentation

ManipExport Plane	(	Point3 &	normal,
		Point3 &	point
	)

Remarks

Constructor.

Create a plane that passes through the given point with the given normal.

Parameters:

Point3& normal

The normal of the plane.

Point3& point

The point the plane should pass through.

ManipExport Plane	(	Point3 &	p1,
		Point3 &	p2,
		Point3 &	p3
	)

Remarks

Constructor.

Create a plane that passes through all three given points.

Parameters:

Points3& p1, Points3& p2, Points3& p3

The three points the plane should pass through.

Member Function Documentation

ManipExport bool Intersect	(	Ray &	ray,
		Point3 &	intersectionPoint
	)

Remarks

This method will intersect the plane with a ray.

Parameters:

Ray& ray

The ray you wish to test for intersection.

Points3& intersectionPoint

The resulting intersection point, if the ray intersected the plane.

Returns

TRUE if the ray intersects, otherwise FALSE.

ManipExport Point3& GetNormal ( )

inline

Remarks

This method returns the normal of the plane.

{ return mNormal; }

ManipExport Point3& GetPoint ( )

inline

Remarks

This method returns the point that the plane passes through.

{ return mPoint; }

ManipExport float GetPlaneConstant ( )

inline

Remarks

This method returns the plane equation constant.

{ return mD; }

ManipExport Plane& MostOrthogonal	(	Ray &	viewDir,
		Plane &	plane
	)

Remarks

This method can be used to test which plane (either this or plane) is most orthogonal with the given view ray, returning that plane. This can be useful in determining which plane to project a view ray onto, if more than one is applicable.

Parameters:

Ray& viewDir

The given view ray.

Plane& plane

The plane to test.

ManipExport FPInterfaceDesc* GetDesc ( )

virtual

Remarks

Returns a pointer to the class which contains the interface metadata.

Implements FPInterface.

ManipExport LifetimeType LifetimeControl ( )

inlinevirtual

Remarks

This method allows inquiries into the actual lifetime policy of a client and provide a server-controlled delete notify callback.

Returns

One of the following LifetimeTypes:

noRelease

Do not call release, use interface as long as you like.

immediateRelease

The interface is only good for one calls. The release is implied so a call to release is not required.

wantsRelease

The clients are controlling the lifetime, so the interface needs a Release() when the client has finished. This is the default.

serverControlled

The server controls the lifetime and will use the InterfaceNotifyCallback to inform the code when it is gone.

Default Implementation:

{ return noRelease; }

Reimplemented from FPMixinInterface.

{ return wantsRelease; }

ManipExport BaseInterface* AcquireInterface ( )

inlinevirtual

Remarks

This method is part of the interface reference management and can be implemented by dynamically allocated interfaces for ref-count based lifetime control). This method should return TRUE if it needs Release() to be called.

Default Implementation:

{ return false; }

Reimplemented from BaseInterface.

{ return this; }

ManipExport void ReleaseInterface ( )

virtual

Remarks

This method is called when a reference to this object is deleted.

Default Implementation:

{ }

Reimplemented from BaseInterface.
