GlsNurbCurve	(	unsigned int	n_points,
		Vertex *	vertices,
		Vertex &	location
	)

NurbCurve Constructor. Creates a new NURBCurve object with the number of vertices and vertex data specified.

Parameters

virtual void CalcNormals ( int windingOrder = 1 )

virtual

Calculates normals based on the vertices and the specified winding order

virtual void CalculateTextureCoordinates ( void )

virtual

Recalculates the texture coordinates for the object based on the TexturePoints.

Reimplemented from DisplayObject.

virtual DisplayObject* CloneObject ( bool generateNames = false )

virtual

Copy+Create operation in one method. In derived classes, this method will create a new instance of the derived class and then copy the object into the new instance. The cut,copy,paste and undo operations use this method.

Parameters

generateNames Whether or not to generate new names for cloned objects

Returns: A new object, identical to the original, except for the instance name

Implements DisplayObject.

virtual void CopyGeometry ( DisplayObject * src )

virtual

Copies the geometry information from one object to another. Used by the undo mechanism to allow user to undo a geometry change.

Parameters

src	The object to copy geometry from

Reimplemented from DisplayObject.

virtual void DeleteVertex ( unsigned int index )

virtual

Remove the Vertex at the given index. This causes tesselated vertices to be recalculated.

Parameters

index The index to remove (1 based)

Reimplemented from DisplayObject.

virtual void Draw ( void )

virtual

Draws this object on the current display frame (_parent member). Pure virtual method

Implements DisplayObject.

void GenerateTessellatedVertices ( void )

Generate a list of vertices describing the NURB curve, save those vertices in the NURBCurve object for use in drawing.

virtual InterfaceListType* GetCppInterfaceDescription ( InterfaceListType * addToThisList = NULL )

virtual

Get the details of the Cpp Interface The actual interface is exposed in compiled code.

Parameters

addToThisList If not NULL this list will be added to then returned. If NULL a new list will be created.

Returns: A templated list. The caller must call the corresponding free method to safely free the memory.

Reimplemented from DisplayObject.

virtual void GetCppInterfaceDescriptionFree ( InterfaceListType * array )

virtual

Frees the memory allocated by a previous call to GetCppInterfaceDescription

Parameters

array Memory allocated by a previous call to GetCppInterfaceDescription

Reimplemented from DisplayObject.

virtual void GetExtents	(	float &	x,
		float &	y,
		float &	z,
		float &	x1,
		float &	y1,
		float &	z1
	)

virtual

Figure out the static extents for the object. Used by the editor as part of the pick operation and for figuring out the size of groups.

Parameters

x	Gets the minimum x extent
y	Gets the minimum y extent
z	Gets the minimum z extent
x1	Gets the maximum x extent
y1	Gets the maximum y extent
z1	Gets the maximum z extent

Reimplemented from DisplayObject.

virtual bool Hit	(	float	x,
		float	y,
		float	z,
		float	scale,
		const Vector &	directionVector,
		Vector *	collisionPoint
	)

virtual

Determines if the object is hit by a pick ray starting at (x,y,z) and pointing towards directionVector in object logical coordinate system. If Pickable() == PICK_BEST it will return the closest point that was hit, otherwise it returns the first point that was hit. This method should not pick points behind the viewer.

Parameters

x	X coordinate of pick ray start in logical coordinates.
y	Y coordinate of pick ray start in logical coordinates.
y	Y coordinate of pick ray start in logical coordinates.
z	Z coordinate of pick ray start in logical coordinates.
scale	The scale factor of the window. Affects picking of outlines. Standard value is 1.0.
directionVector	The direction of the pick ray.
collisionPoint	If this method returns true, this Vector will contain the location that was hit in logical coordinates.

Returns: boolean indicating if the object was hit by the pick ray.

Reimplemented from DisplayObject.

unsigned int NumberOfTessVertices ( ) const

inline

Gets the object's number of Tesselated vertices. These tesselated vertices are generated by the NURB render function.

Returns: The number of vertices in the object

virtual void PreDraw	(	const OpenGLMatrices &	current,
		Culler &	culler
	)

virtual

Traverses the hierarchy calculating the _modelMatrix, _projMatrix, _viewMatrix as needed.

Parameters

current	Current matrices inherited from parent
culler	Object that possibly marks this object for culling

Reimplemented from DisplayObject.

virtual void Rotate	(	const Vector &	orig,
		float	angle,
		const Vector &	axis
	)

virtual

Rotates the object (around the specified axis) by the angle indicated, at the point specified. Recalculates the vertex data.

Parameters

orig	The point to rotate around
angle	The angle to rotate by, in degrees
axis	The arbitrary axis to rotate the object around

Reimplemented from DisplayObject.

void Scale	(	float	px,
		float	py,
		float	pz,
		Vertex *	anchor,
		int	handleBar
	)

virtual

Scales the object, either the handleBar, or the Anchor is used to translate the object, not both. Anchor takes presidence, if it is set HandleBar is ignored. The footprint is different from the 2D scale so the compiler can destinguish the two.

Parameters

px	Value of the percentage of scale in x-axis
py	Value of the percentage of scale in y-axis
pz	Value of the percentage of scale in z-axis
anchor	Anchor from which to scale object relative to
handleBar	Vertex that is being dragged

Reimplemented from DisplayObject.

virtual void SetAvailableAttributes ( unsigned int value )

virtual

Specifies which attributes are available for the object. Currently the available attributes cannot be changed after they have been set. (Only the first call has an effect.)

Parameters

value A bitfield specifying which types of attributes to make available.

See also: AvailableAttributesEnum

Reimplemented from DisplayObject.

virtual void SetFillColor ( const GlsColor & color )

virtual
