Detailed Description

template<unsigned D>
class VertexData< D >

Base class for all Rotope s.

Contains an array of vertices (Vectors) and a function to print them. This is used mainly in the development of Rotope objects.

Template Parameters:

D	Dimension of the vector space we're working in

Todo:

transforming rotopes, allowing for rotation in D dimensions and scaling.

Member Function Documentation

template<unsigned D>

void VertexData< D >::addTransform	(	unsigned	d,
		const VecMath::RotationBase *	R
	)		[protected, virtual]

Perform a D -dimensional transformation.

Parameters:

R	Rotation component of the transformation
d	Dimension on which the transform acts

Implements RotopeInterface.

References std::cerr.

template<unsigned D>

virtual unsigned& VertexData< D >::dimension

(

)

[inline, virtual]

Direct access to the dimension member instead of setter for convenience.

This way, implementing classes can simply use

    VertexData<D>::dimension()++;

instead of the more cumbersome

  VertexData<D>::setDimension(VertexData<D>::dimension()+1);

Because Rotope operations (extrusion, tapering etc.) are all about increasing the dimension, I'll let this stand.

Implements RotopeInterface.

References VertexData< D >::_dimension.

template<unsigned D>

std::vector< VecMath::Vector< 4 > > VertexData< D >::projected_vertices

(

)

[virtual]

The array of vertices, projected to four dimensions if necessary.

Todo:

This is hardcoded! Ugh!

Implements RotopeInterface.
