Description

This class represents toroidal segments.

Remarks

The torus is surface generated by revolving a circular arc about an axis of symmetry, where the plane of the circular arc contains the axis of symmetry

The torus is located in space by its center, which is a point on the axis of symmetry.

The center of the circular arc is at a distance of majorRadius from the center of the torus. The radius of the circular arc is the minorRadius.

Parameter U parameterizes the circular tube, which for a closed circle defaults to the range [-OdaPI, OdaPI). Applying the right hand rule along the (axisOfSymmetry X refAxis) defines the increasing direction for U.

Parameter V is the longitude (about the axis of symmetry), which for a closed torus defaults to the range [-OdaPI, OdaPI). Zero corresponds to the refAxis (which is a vector orthogonal to the axis of symmetry). Applying the right hand rule along the symmetric axis defines the increasing direction for V. However, if isReverseV() is true, the increasing direction for V is defined by the left hand rule.

The torus is periodic in U, V with a period of Oda2PI. [umin, umax] x [vmin, vmax] defines a four sided toroidal patch bounded by four circular arcs. Following constraints apply to the definition of a toroidal patch.

umin < umax and |umin - umax| <= Oda2PI.
vmin < vmax and |vmin - vmax| <= Oda2PI

OdGeTorus Methods

	Name	Description
	axisOfSymmetry	Returns the axis of symmetry (rotation) of this torus.
	center	Returns the center of this torus.
	getAnglesInU	Retrieves the start and end angles about the axis of symmetry.
	getAnglesInV	Retrieves the start and end angles about the tube.
	intersectWith	Checks if the torus intersects with the specified line entity, and returns the number of intersections and the points of intersection.
	isApple	Checks if (0 < majorRadius < \|minorRadius\| - OdGeContext::gTol.equalVector()), creating a solid with dimples at the axis of symmetry.
	isDegenerate	Checks if torus is not Doughnut.
	isDoughnut	Checks if (majorRadius >= \|minorRadius\| - OdGeContext::gTol.equalVector()), creating a solid with a hole in the middle.
	isHollow	Checks if the minor radius of the torus is less than zero.
	isLemon	Checks if (majorRadius <= 0), producing a solid with points along the axis of symmetry.
	isOuterNormal	Checks if the normal to this surface is pointing outward.
	isReverseV	Checks whether V parameter increases in clockwise direction around axisOfSymmetry.
	isVortex	Checks if (\|majorRadius - \|minorRadius\|\| < OdGeContext::gTol.equalVector()), producing a doughnut. with a zero-radius hole.
	majorRadius	Returns the major radius of this torus.
	minorRadius	Returns the minor radius of this torus.
	refAxis	Returns the reference axis of this torus.
	set	This is the overview for the set method overload.
	setAnglesInU	Sets the start and end angles about about the axis of symmetry.
	setAnglesInV	Sets the start and end angles about about the tube.
	setMajorRadius	Sets the major radius of this torus.
	setMinorRadius	Sets the minor radius of this torus.
	setReverseV	Specifies whether the V parameter should be measured clockwise around axisOfSymmetry, rather than counterclockwise.
