Detailed Description

The GlsPolygon abstracts an ordered set of two or more textured vertices.

Invariant: base class invariant holds, _vertices.Invariant()

Constructor & Destructor Documentation

GlsPolygon::GlsPolygon	(	const InitParameters &	initParameters,
		GlsEventDispatcher *const	eventDispatcher
	)

Constructor - create instance

Parameters

initParameters	initialization parametets
eventDispatcher	event dispatcher for this object else GLS_NULL

Precondition: initParameters.IsValid()

Postcondition: instance created

virtual GlsPolygon::~GlsPolygon ( )

protectedvirtual

Destructor - shall never be called

Precondition: none

Postcondition: none

Member Function Documentation

virtual void GlsPolygon::Draw	(	GlsStateManager &	gl,
		const GlsFloat64	time
	)

virtual

Draws this polygon

Parameters

gl	GL State manager for OpenGL into which polygon is drawn
time	the elaspsed time in seconds since program start

Precondition: time >= 0.0

Postcondition: polygon is drawn to OpenGL if visible and not blinked off

Implements GlsDisplayObject.

virtual void GlsPolygon::OffsetTexture ( const GlsVector2D & offset )

virtual

Offset the texture on the object

Parameters

offset x, y offset for texture

Precondition: offset.IsValid()

Postcondition: offset is added to the texture coordinates

Implements GlsRenderObject.

void GlsPolygon::SetVertex	(	const GlsUInt32	index,
		const GlsTextureVertex &	vertex
	)

Set one of the vertices in the polygon

Parameters

index	index of desired vertex
vertex	new value of desired vertex

Precondition: index is less than the number of vertices in the polygon, vertex.IsValid()

Postcondition: vertex at desired index has new value
