Detailed Description

Interface for accessing informations in the three drawable "interactive" filter elements in kernel/src/rangeelementinteractive.h (polygon,rectangle,ellipse)

These elements are defined by a list of vertices (DVect3), a projection mode (parallel/perspective), and, if the projection is in perspective mode, by an origin point (DVect3).
This projection mode correspond to the one which was active WHEN THE RANGE WAS CREATED.
Therefore, if in perspective projection, the shape of the filter element region is a cone with its top at the origin point.
Note - an ellipse is stored internally via its circumscribed rectangle

Member Function Documentation

addVertex()

virtual bool itascaxd::IRangeElementPolygonBased::addVertex ( const DVect & vec )

pure virtual

Returns true and adds a new vertex to the list of vertices (push_back) if this new vertex is in the plane defined by previous vertices in the list.
Returns false without adding the vertex if not.

setVertices()

virtual bool itascaxd::IRangeElementPolygonBased::setVertices ( const QVector< DVect > & list )

pure virtual

Checks internally if list's vertices define a plane. Returns false without any copy if not, otherwise returns true and sets (by copy) the list of vertices that delimitate a polygonal shape in 3D "real" coordinates
