Detailed Description

The Polygon class. Implements Polygons.

Constructor & Destructor Documentation

GLPolygon ( unsigned int  nPoints,
Vertex *  vertices 
)

Creates a polygon with the vertices specified

Parameters
nPointsThe number of vertices in the new polygon
verticesThe array of vertices for the polygon
GLPolygon ( unsigned int  nPoints,
Vertex *  vertices,
Vertex &  location 
)

Creates a polygon with the vertices specified

Parameters
nPointsThe number of vertices in the new polygon
verticesThe array of vertices for the polygon
locationThe location point of the object
GLPolygon ( void  )

Allocate a (blank) polygon object

GLPolygon ( const GLPolygon &  polygon,
const bool  generateNames 
)

Copy construct a new GLPolygon object

Parameters
polygonThe polygon to be cloned
generateNamesWhether or not to generate a new instance name
virtual ~GLPolygon ( void  )
virtual

Destroy a polygon 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.

Reimplemented in GlsSchematicTeeInterconnect, GlsSchematicPolyLineInterconnect, and GlsEllipse.

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.

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

void ConfigureMetaData ( void  )

Configures MetaData

virtual void DeleteVertex ( unsigned int  index)
virtual

DeleteVertex 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

Reimplemented from DisplayObject.

Reimplemented in GlsPolyLine, and GlsSchematicPolyLineInterconnect.

virtual void Draw ( void  )
virtual

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

Implements DisplayObject.

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

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
winLocDevice coordinates for the mouse click. Z value should be set to 0 to ensure pick ray starts at near clip plane.
logicalCoordsThe start of the pick ray in logical coordinates. Should be calculated from the winLoc using this->WindowToLogical(winLoc, logicalCoords, &directionVector).
scaleCurrent window scale. Affects picking radius of outlines. Initial value should typically be 1.0.
directionVectorThe direction of the pick ray in logical coordinates. Should be calculated from the winLoc using this->WindowToLogical(winLoc, logicalCoords, &directionVector).
collisionWinLocReturns where the pick vector intersects the object that is hit in device coordinates.
drawnMatricesThe 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
