Detailed Description

The Geometry class wraps the vertices data of one drawable object.

Vertices data is stored as an index and a vertex buffer. In order to get rendered, a game object has to reference one geometry.

Constructor & Destructor Documentation

terminus::Geometry::Geometry	(	const std::vector< unsigned short > &	indexBuffer,
		const std::vector< Vertex > &	vertexBuffer
	)

General geometry constructor.

Parameters

indexBuffer
vertexBuffer	Supplied geometry data will be stored in the respective member. If no BBox values are given, the BBox will be calculated automatically.

terminus::Geometry::Geometry	(	const std::vector< unsigned short > &	indexBuffer,
		const std::vector< Vertex > &	vertexBuffer,
		const QVector3D &	minBBox,
		const QVector3D &	maxBBox
	)

void terminus::Geometry::setAttributes ( Program &  program )

virtual

The geometry specific attributes position, texture coordinate and normal vector are set on the used program.

Parameters
