Function: pcirc

Syntax

pcirc( {<window>} )

Type

point

Returns

The position of a 2-D circle defined via an interactive circle operation. Two point values are returned, the circle center, and a point on its circumference.

Since the system operates in three dimensions, any required third coordinate will be taken from the current value of the graphic control position (gc) when the view is orthographic, or from the focus position when the view is perspective.

Parameters

<window>
The graphic window to be used as input. If omitted, any graphic window may be selected.

Examples

Gets two points via a rubber circle in any graphic window selected by the user.

point p[2] = pcirc

Gets two points via a rubber circle in a specific graphic window.

point p[2] = pcirc(mywin)
