Constructor & Destructor Documentation

GlsNurbCurve ( unsigned int  nPoints,
Vertex vertices 
)

Creates a NURB Curve with the vertices specified

Parameters
nPointsNumber of control points in the NURB
verticesAn array of allocated vertices
Precondition
vertices is not NULL
GlsNurbCurve ( bool  generateInstanceName = false)

Allocate a (blank) NURB Curve object

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
n_pointsNumber of control points in the NURB
verticesAn array of allocated vertices
locationInitial location of the NURB
virtual ~GlsNurbCurve ( )
virtual

Destructs a GlsNurbCurve object

Member Function Documentation

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
generateNamesWhether 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
srcThe 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
indexThe 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
addToThisListIf 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
arrayMemory 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
xGets the minimum x extent
yGets the minimum y extent
zGets the minimum z extent
x1Gets the maximum x extent
y1Gets the maximum y extent
z1Gets 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
xX coordinate of pick ray start in logical coordinates.
yY coordinate of pick ray start in logical coordinates.
yY coordinate of pick ray start in logical coordinates.
zZ coordinate of pick ray start in logical coordinates.
scaleThe scale factor of the window. Affects picking of outlines. Standard value is 1.0.
directionVectorThe direction of the pick ray.
collisionPointIf 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
currentCurrent matrices inherited from parent
cullerObject 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
origThe point to rotate around
angleThe angle to rotate by, in degrees
axisThe 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
pxValue of the percentage of scale in x-axis
pyValue of the percentage of scale in y-axis
pzValue of the percentage of scale in z-axis
anchorAnchor from which to scale object relative to
handleBarVertex 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
valueA bitfield specifying which types of attributes to make available.
See also
AvailableAttributesEnum

Reimplemented from DisplayObject.

virtual void SetFillColor ( const GlsColor color)
virtual

Sets the RGBA color for filling the object

unsigned char  CurrentFillColor[] 
)
virtual

Changes the color of a vertex

Parameters
