Detailed Description

This class encapsulates a mesh of triangle faces.

Invariant: base class invariant holds, GLS_NULL != _faces, _numFaces > 0u, _vertices invariant holds, for each element in _faces: v1,v2,v3 < _vertices.GetSize(), textureIndex < _texturePalette.GetSize()

Constructor & Destructor Documentation

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

Constructor - create an instance

Parameters

initParameters	initialization parameters
eventDispatcher	event dispatcher for this object else GLS_NULL

Precondition: initParameters.isValid()

Postcondition: instance is created

virtual GlsTriangleMesh::~GlsTriangleMesh ( )

protectedvirtual

Destructor - shall never be called

Precondition: none

Postcondition: none

Member Function Documentation

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

virtual

Draws the triangle mesh

Parameters

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

Precondition: time >= 0.0

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

Implements GlsDisplayObject.

virtual void GlsTriangleMesh::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.

virtual void GlsTriangleMesh::SetTextureIndex ( const GlsUInt32 textureIndex )

virtual

Set the desired texture index

Parameters

textureIndex desired texture index into palette else GlsTexturePalette::NO_TEXTURE

Precondition: textureIndex is less than the size of the texture palette, else GlsTexturePalette::NO_TEXTURE, object's texture palette must have a valid texture (not an empty palette entry) at textureIndex if textureIndex != GlsTexturePalette::NO_TEXTURE

Postcondition: object has new texture index or is untextured if textureIndex == GlsTexturePalette::NO_TEXTURE

Reimplemented from GlsRenderObject.
