DESCRIPTION

This class handles all problems with input data, such as collinear points, Identical points, Non-coplanar polygons, etc and returns a set of objects that best represents it. Non-coplanar polygons are chopped up arbitrarily.

RiPolygonBuilder(Products wanted );

Default Constructor

    RiPolygonBuilder(Products wanted = noneFlag);

~RiPolygonBuilder() ;;

 Destructor

    virtual ~RiPolygonBuilder()   ;
;

Function is currently defined inline.

void SetMaterial(RiMaterial *);

 Set the material to be used for all subsequent polygons until a new material is set

    void		SetMaterial(RiMaterial *);

void SetNormal(const RiUnitVector3 &normal);

 Set a normal to be used FOR THIS POLYGON ONLY stays valid until it is set again, and should be set before the AddPoint associated with it

    void		SetNormal(const RiUnitVector3 &normal);

void SetUV(const RiVector2 &uv);

 Set a uv to be used FOR THIS POLYGON ONLY stays valid until it is set again, and should be set before the AddPoint associated with it

    void		SetUV(const RiVector2 &uv);

void AddPoint(const RiVector3 &point);

 Add another point on the polygon. Assumes they are added in counter-clockwise order.

    void		AddPoint(const RiVector3 &point);

bool Build();

 Build the objects.

    virtual bool  	Build();

bool BuildTriMesh(int numVertices, int numTris, RiVector3 *verts, RiUnitVector3 *norms, RiVector2 *uvs, int *vertexIndices);

 Data adopted

    bool  	 BuildTriMesh(int numVertices, int numTris, RiVector3 *verts, RiUnitVector3 *norms,
			      RiVector2 *uvs, int *vertexIndices);
