BrepTrimGetTolerances Method

public void GetTolerances(
	out double toleranceU,
	out double toleranceV
)

Public Sub GetTolerances ( 
	<OutAttribute> ByRef toleranceU As Double,
	<OutAttribute> ByRef toleranceV As Double
)

Parameters

toleranceU

Type: SystemDouble

[Missing <param name="toleranceU"/> documentation for "M:Rhino.Geometry.BrepTrim.GetTolerances(System.Double@,System.Double@)"]

toleranceV

Type: SystemDouble

[Missing <param name="toleranceV"/> documentation for "M:Rhino.Geometry.BrepTrim.GetTolerances(System.Double@,System.Double@)"]

tolerance[0] = accuracy of parameter space curve in first ("u") parameter

tolerance[1] = accuracy of parameter space curve in second ("v") parameter

A value of RhinoMath.UnsetValue indicates that the tolerance should be computed. If the value >= 0.0, then the tolerance is set. If the value is RhinoMath.UnsetValue, then the tolerance needs to be computed.

If the trim is not singular, then the trim must have an edge. If P is a 3d point on the edge's curve and surface(u,v) = Q is the point on the surface that is closest to P, then there must be a parameter t in the interval [m_t[0], m_t[1]] such that |u - curve2d(t)[0]| <= tolerance[0] and |v - curve2d(t)[1]| <= tolerance[1] If P is the 3d point for the vertex brep.m_V[m_vi[k]] and (uk,vk) is the corresponding end of the trim's parameter space curve, then there must be a surface parameter (u,v) such that:

• the distance from the 3d point surface(u,v) to P is <= brep.m_V[m_vi[k]].m_tolerance,
• |u-uk| <= tolerance[0].
• |v-vk| <= tolerance[1].
