PROTECTED METHOD SUMMARY

virtual ~vzVertexArray (

CLASS DESCRIPTION

vzVertexArray provides an abstraction for storing an array of vertex coordinates. Stores a user data pointer for an array of floats, but does not perform any memory allocation.

METHOD DESCRIPTIONS

   vzVertexArray()

vzVertexArray (

int numVertices, float* vertices);

Constructor for vzVertexArray. Calls setDataPtr() with numVertices and vertices as arguments.

   ~vzVertexArray()

virtual ~vzVertexArray (

);

Destructor for vzVertexArray.

   computeBoundingBox()

void computeBoundingBox (

float bbox[6]) const;

Compute and return the bounding box for the given set of vertices. The first three floating point values in bbox give the corresponding x, y and z coordinates of the lower bound and the next three give the upper bound.

   getDataPtr()

float* getDataPtr (

) const;

Return the pointer to the array of vertices.

   getNumVertices()

int getNumVertices (

);

Return the number of vertices in the array.

   setDataPtr()

void setDataPtr (

int numVertices, float* vertices);

Set the list of numVertices vertices of the model to the specified values. Values should be provided in the form (x1,y1,z1,x2,y2,z2,...) setDataPtr performs a shallow copy of vertices: no memory allocation is performed. The method also marks the vertex data as dirty, invoking all notification callbacks. You must call this method whenever you modify vertex data.
