RhinoCommonExtensionMethods

public static class RhinoCommonExtensionMethods
Some extension methods for various RhinoCommon types.

Methods

AddSphere

#Example
public static void AddSphere(this CustomDisplay display, Sphere sphere, Color colour, int thickness)
Parameters:
display (CustomDisplay)
sphere (Sphere)
colour (Color)
thickness (int)

AddSphere

#Example
public static void AddSphere(this CustomDisplay display, Sphere sphere)
Parameters:
display (CustomDisplay)
sphere (Sphere)

FindCusps

#
public static IEnumerable<double> FindCusps(NurbsCurve curve, int spanIndex)
Find parameters where cusps occur within the given interval. Note that the limits of the interval are rejected as possible cusp locations.
Parameters:
curve (NurbsCurve)
spanIndex (int)

FindCusps

#Example
public static IEnumerable<double> FindCusps(this NurbsCurve curve)
Find parameters where cusps occur within the interior of spans.
Parameters:
curve (NurbsCurve)The NURBS curve to analyse.

FocusWindowNAH

#Example
public static void FocusWindowNAH(this RhinoDoc doc)
Make sure the Rhino window hosting the specified document has focus.
Parameters:
doc (RhinoDoc)

GetContinuityLevel

#Example
public static DiscontinuityLevel GetContinuityLevel(this Curve curve, double t, double angleTolerance = 0.01, double relativeTolerance = 0.01)
Evaluate the level of discontinuity at a given curve parameter.
Parameters:
curve (Curve)Curve.
t (double)Parameter on curve.
angleTolerance (double = 0.01)Angle tolerance between normalised derivatives in radians.
relativeTolerance (double = 0.01)Relative tolerance between normalised derivatives.
Returns: Highest level of continuity.

HasSelectableObjects

#Example
public static bool HasSelectableObjects(this ObjectTable objects, ObjectType type)
Gets whether this document contains any selectable (i.e. non-hidden and non-locked) object of the given type.
Parameters:
objects (ObjectTable)
type (ObjectType)

Invert

#Example
public static DisplayMaterial Invert(this DisplayMaterial material)
Create a new material with inverted back and front face properties.
Parameters:
material (DisplayMaterial)

MakeClosedViaLine

#Example
public static Curve MakeClosedViaLine(this Curve curve)
Close a curve by inserting a line segment from the end to the start point.
Parameters:
curve (Curve)Curve to close. If curve is already closed, it will be returned immediately.
Returns: Closed curve or null.

RedrawAndReturnImmediately

#Example
public static void RedrawAndReturnImmediately(this RhinoDoc document)
Redraw all Rhino viewports. All GH code should use this method rather than ViewTable.Redraw().
Parameters:
document (RhinoDoc)Document whose viewports to redraw.

Reflex

#Example
public static Arc Reflex(this Arc arc)
Get the reflex arc.
Parameters:
arc (Arc)

RegionIndices

#Example
public static int[] RegionIndices(this CurveBooleanRegions regions, int regionIndex, int[] indexMap = null)
Find all the indices of input curves that went into a specific region.
Parameters:
regions (CurveBooleanRegions)
regionIndex (int)
indexMap (int[] = null)
