Detailed Description

base class for subclasses that generate analytic vertex attribute data.

Constructor & Destructor Documentation

VRS::VertexAttributeGenerator::VertexAttributeGenerator	(	unsigned int	nx,
		unsigned int	ny
	)

A VertexAttributeGenerator is a base class of classes that create analytical vertex attribute data that fits in a mesh. The tesselation of the mesh is given by nx and ny, i.e., the exact mesh dimension is (nx+1)*(ny+1)

Beware: this is no SharedObj! As this class and sub-classes will be used internally in VRS only, and only by simplifier classes, this seems to be no big problem.

Derived classes often create temporary data, which must be deleted in their destructor.

Member Function Documentation

virtual Iterator<Vector>* VRS::VertexAttributeGenerator::calcVertexData

(

const ID &

vertexDataType

)

[virtual]

For the given abtract vertex data type (as defined in VertexAttributeMap), generates an Iterator that contains the vertex data for further use in a mesh. The VertexAttributeGenerator can generate

• VertexAttributeMap::UV_PARAMETER (simple parametrisation of the mesh)
• VertexAttributeMap::BINORMAL (by creating NORMAL and TANGENT data and calculating the cross-product). Other data must be created by subclasses for concrete analytic shapes.

Reimplemented in VRS::BoxSideGenerator, VRS::ConeGenerator, VRS::CylinderGenerator, VRS::DiscGenerator, VRS::HyperboloidGenerator, VRS::KnotGenerator, VRS::ParaboloidGenerator, VRS::SphereGenerator, VRS::SuperQuadGenerator, and VRS::TorusGenerator.

virtual Matrix VRS::VertexAttributeGenerator::getTransform

(

)

const [virtual]

Returns the transformation matrix which should be applied to the shape for correct location and orientation.

Reimplemented in VRS::ConeGenerator, VRS::CylinderGenerator, VRS::DiscGenerator, and VRS::SphereGenerator.
