Detailed Description

template<typename T>
class VertexStorage< T >

Defines a class to store Vertex information.

This class is used to translate OpenInventor triangle models into ODE triangles.

Template Parameters:

T

type of the vertices to be stored

Definition at line 73 of file VertexStorage.h.

Constructor & Destructor Documentation

template<typename T >

VertexStorage< T >::VertexStorage	(	int	maxVertexCount,
		int	maxIndexCount
	)			[inline]

Initialise the class with the number of verticis and indices it is going to hold. Additionally an array of size maxVertexCount and type T and an array of size maxIndexCount and type int are created.

Template Parameters:

T

type of the vertices to be stored

Parameters:

	maxVertexCount	maximal number of vertices the class is going to hold.
	maxIndexCount	maximal number of indicees the class is going to hold.

Definition at line 104 of file VertexStorage.h.

template<typename T >

VertexStorage< T >::~VertexStorage

(

)

[inline]

Delete both vertex and index array and their contents if they aren't NULL.

Member Function Documentation

template<typename T >

bool VertexStorage< T >::appendVertex

(

T

vertex

)

[inline]

Append a vertex after the last inserted vertex. Increments nextVertex by one.

Parameters:

vertex

the vertex to append to VertexStorage::vertices.

Returns:

true if vertex was added.

false if VertexStorage::vertices is full.

Definition at line 139 of file VertexStorage.h.

template<typename T >

bool VertexStorage< T >::appendVertexIndices	(	int	idx1,
		int	idx2,
		int	idx3
	)			[inline]

Append the index numbers for the last inserted vertex. VertexStorage<T>::appendVertex() should be called before or you must be sure that the added indices match the vertices in the vertex array.

Parameters:

	idx1	first index of vertex
	idx2	second index of vertex
	idx3	third index of vertex

Returns:

true if indices were added correctly

false if the indices couldn't be inserted (VertexStorage::indices is full)

template<typename T >

bool VertexStorage< T >::appendVertexWithIndices	(	T	vertex,
		int	idx1,
		int	idx2,
		int	idx3
	)			[inline]

Insert a vertex and the according indices.
Calls VertexStorage::appendVertex() and afterwards VertexStorage::appendVertexIndices(). If the indices could not be inserted the vertex gets "deleted" from VertexStorage::vertices by decrementing VertexStorage::nextVertex.

Parameters:

	vertex	the vertex to append
	idx1	first index of vertex
	idx2	second index of vertex
	idx3	third index of vertex

Returns:

false if an error happened

true if everything went fine.

template<typename T>

VertexStorage< T >::getIndexCount

(

)

Returns:

the number of currently stored indices

template<typename T>

VertexStorage< T >::getVertexCount

(

)

Returns:

the number of currently stored vertices
