Cylinder Structure
Represents the values of a plane, a radius and two heights -on top and beneath- that define a right circular cylinder.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: 5.1.50000.0 (5.0.20693.0)
Syntax
[SerializableAttribute]
public struct Cylinder : IEpsilonComparable<Cylinder>

The Cylinder type exposes the following members.

Constructors
  NameDescription
Public methodCylinder(Circle)
Constructs a new cylinder with infinite height.
Public methodCode exampleCylinder(Circle, Double)
Constructs a new cylinder with a finite height.

Properties
  NameDescription
Public propertyAxis
Gets the axis direction of the cylinder.
Public propertyCenter
Gets the center point of the defining circle.
Public propertyHeight1
Gets or sets the start height of the cylinder.
Public propertyHeight2
Gets or sets the end height of the cylinder. If the end height equals the start height, the cylinder is presumed to be infinite.
Public propertyIsFinite
true if the cylinder is finite (Height0 != Height1) false if the cylinder is infinite.
Public propertyIsValid
Gets a boolean value indicating whether this cylinder is valid.

A valid cylinder is represented by a valid circle and two valid heights.

Public propertyTotalHeight
Gets the height of the cylinder. Infinite cylinders have a height of zero, not Double.PositiveInfinity.
Public propertyStatic memberUnset
Gets an invalid Cylinder.

Methods
  NameDescription
Public methodCircleAt
Compute the circle at the given elevation parameter.
Public methodEpsilonEquals
Check that all values in other are within epsilon of the values in this
Public methodEquals
Indicates whether this instance and a specified object are equal.
(Inherited from ValueType.)
Public methodGetHashCode
Returns the hash code for this instance.
(Inherited from ValueType.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
