Detailed Description

The Polygon class. Implements Polygons.

Constructor & Destructor Documentation

◆ GLPolygon() [1/4]

GLPolygon	(	unsigned int	nPoints,
		const Vertex *	vertices
	)

Creates a polygon with the vertices specified

Parameters

nPoints	The number of vertices in the new polygon
vertices	The array of vertices for the polygon

◆ GLPolygon() [2/4]

GLPolygon	(	unsigned int	nPoints,
		const Vertex *	vertices,
		const Vertex &	location
	)

Creates a polygon with the vertices specified

Parameters

nPoints	The number of vertices in the new polygon
vertices	The array of vertices for the polygon
location	The location point of the object

◆ GLPolygon() [3/4]

GLPolygon ( )

Allocate a (blank) polygon object

◆ GLPolygon() [4/4]

GLPolygon	(	const GLPolygon &	polygon,
		const bool	generateNames
	)

Copy construct a new GLPolygon object

Parameters

polygon	The polygon to be cloned
generateNames	Whether or not to generate a new instance name

◆ ~GLPolygon()

virtual ~GLPolygon ( )

virtual

Destroy a polygon object

Member Function Documentation

◆ CalcNormals()

virtual void CalcNormals ( int windingOrder = 1 )

virtual

Calculates normals based on the vertices and the specified winding order.

Parameters

windingOrder Multiply calculated normals by -1 if less than 0.

◆ CalculateTextureCoordinates()

virtual void CalculateTextureCoordinates ( )

virtual

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

Reimplemented from DisplayObject.

Reimplemented in GlsEllipse, GlsSchematicPolyLineInterconnect, and GlsSchematicTeeInterconnect.

◆ CloneObject()

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.

Reimplemented in GlsAngularScale, GlsCTLTextBox, GlsEllipse, GlsLinearScale, GlsMovieTexture, GlsNinePatch, GlsPolyLine, GlsSchematicPolyLineInterconnect, GlsSchematicTeeInterconnect, GlsTextBox, GlsTextGrid, GlsVideoToTexture, and GLTriMesh.

◆ ConfigureMetaData()

void ConfigureMetaData ( )

Configures MetaData

◆ CreateInstance()

static DisplayObject * CreateInstance ( )

static

Returns: A new GLPolygon instance.

◆ DeleteVertexAt()

virtual void DeleteVertexAt ( unsigned int index )

virtual

DeleteVertexAt is overloaded in polygon to prevent having a poly with less than 2 verts. This prevents incorrect GL calls when polygon is set to POLY_MODE_FILLED

Parameters

index The index of the vertex to delete.

Reimplemented from DisplayObject.

Reimplemented in GlsPolyLine, and GlsSchematicPolyLineInterconnect.

◆ Draw()

virtual void Draw ( )

virtual

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

Implements DisplayObject.

Reimplemented in GlsAngularScale, GlsCTLTextBox, GlsEllipse, GlsLinearScale, GlsMovieTexture, GlsNinePatch, GlsPolyLine, GlsSchematicPolyLineInterconnect, GlsSchematicTeeInterconnect, GlsTextBox, GlsTextGrid, GlsVideoToTexture, and GLTriMesh.

◆ Pick3D()

virtual DisplayObject * Pick3D	(	const Vector &	winLoc,
		const Vector &	logicalCoords,
		float	scale,
		const Vector &	directionVector,
		Vector &	collisionWinLoc,
		const OpenGLMatrices &	drawnMatrices
	)

virtual

Attempts to pick an object in 3D and accounting for dynamic rotations and translations of this object or parent objects. It also looks at the pickable status and attempts to return the "Best" pick if that is what is desired.

Note: This method will pick objects in the scene based on a pick ray starting at winLoc and pointing into the screen. It will not pick objects behind the depth specified by winLoc.z. Typically winLoc.z should be set to 0 to ensure that the pick ray starts at near clip plane.

Parameters

winLoc	Device coordinates for the mouse click. Z value should be set to 0 to ensure pick ray starts at near clip plane.
logicalCoords	The start of the pick ray in logical coordinates. Should be calculated from the winLoc using this->WindowToLogical(winLoc, logicalCoords, &directionVector).
scale	Current window scale. Affects picking radius of outlines. Initial value should typically be 1.0.
directionVector	The direction of the pick ray in logical coordinates. Should be calculated from the winLoc using this->WindowToLogical(winLoc, logicalCoords, &directionVector).
collisionWinLoc	Returns where the pick vector intersects the object that is hit in device coordinates.
drawnMatrices	The matrices used to draw the object, including matrices set by parents that may have dynamically rotated, translated or scaled this object. Initial value should typically be a default OpenGLMatrices() object.

Returns: The object that was hit, or NULL if no object hit
