[F90:]subroutine gSetArcTolerance(tol) real, intent(in) :: tol
Arguments
tol
Maximum distance in current units between the circumference of a smooth arc and straight line segment generated as a representation of the arc
Description
The routine gSetArcTolerance() controls the smoothness of arcs and standard GINO curves.
It sets the tolerance to which arcs must be drawn if hardware arcs are not being drawn.
GINO will approximate to arcs by drawing an inscribed polygon such that the maximum distance between the required arc and the approximating polygon is tol. If tol = 0.0 the default value is restored. The arc tolerance is ignored if hardware arcs are being drawn.
