Detailed Description

THIS SOFTWARE IS PROVIDED "AS IS" WITHOUT EXPRESS OR IMPLIED WARRANTY. ALL IMPLIED WARRANTIES OF FITNESS FOR ANY PARTICULAR PURPOSE AND OF MERCHANTABILITY ARE HEREBY DISCLAIMED.

For complete openNURBS copyright information see http://www.opennurbs.org. Description: An ON_Arc is a subcurve of 3d circle. Details: The curve is parameterized by an angle expressed in radians. For an IsValid() arc the total subtended angle AngleRadians() = Domain()(1) - Domain()(0) must satisfy 0< AngleRadians() <2*Pi .

The parameterization of the ON_Arc is inherited from the ON_Circle it is derived from. In particular t -> center + cos(t)*radius*xaxis + sin(t)*radius*yaxis
where xaxis and yaxis, (part of ON_Circle::m_plane) form an othonormal frame of the plane containing the circle.
