Class: DefInterpolate

algeobra~DefInterpolate(topt)

Definition of a linear interpolation between two objects of the same type by some parameter t. Supported types are (type of interpolation in brackets): TYPE_NUMBER (value) TYPE_POINT (coordinates) TYPE_VECTOR (coordinates and reference point) TYPE_POLAR (coordinates) TYPE_ANGLE (angle, start and reference point) TYPE_ARC (center, radius, start angle, end angle) TYPE_ELLIPSE (center, eccentricities, start angle, end angle, rotation) TYPE_LINE (points, Opennness is determined by logical OR) TYPE_LINE_STRIP (points) TYPE_POLYGON (points) TYPE_BEZIER (points) TYPE_BEZIER_SPLINE (points)
