A circle arc skeletal element.
Example of how to code a circular arc primitive:
,
TreeCircleArc::TreeCircleArc | ( | const Vector & | a, |
const Vector & | b, | ||
const Vector & | c, | ||
BlendCompact * | blend | ||
) |
Creates a circular-arc element.
The circular-arc is defined by three vertices that define a circle in the corresponding plane. As there are two possible arcs given three vertices, the arc type is defined by order of vertices which the orientation of the arc.
a,b,c | Three vertices on the circle defining the circular arc abc. |
blend | Falloff function. |
TreeCircleArc::TreeCircleArc | ( | const CircleArc & | arc, |
BlendCompact * | blend | ||
) |
Creates a circular-arc element.
arc | Circle arc. |
blend | Falloff function. |
