使用Grasshopper：如果我将域传递给 Python 组件，python 会将其视为一个区间。我可以对其进行操作，如下所示：

print x
x.Grow(x[0]-y)
x.Grow(x[1]+y)

print x    
print type(x)
print dir(x)

哪个打印：

20.3596657850938,87.5596657850938
19.3596657850938,88.5596657850938
<type 'Interval'>
['CompareTo', 'EpsilonEquals', 'Equals', 'FromIntersection', 'FromUnion', 'GetHashCode', 'GetObjectData', 'GetType', 'Grow', 'IncludesInterval', 'IncludesParameter', 'IsDecreasing', 'IsIncreasing', 'IsSingleton', 'IsValid', 'Item', 'Length', 'MakeIncreasing', 'Max', 'MemberwiseClone', 'Mid', 'Min', 'NormalizedIntervalAt', 'NormalizedParameterAt', 'ParameterAt', 'ParameterIntervalAt', 'ReferenceEquals', 'Reverse', 'Swap', 'T0', 'T1', 'ToString', 'Unset', '__add__', '__class__', '__delattr__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__init__', '__le__', '__lt__', '__ne__', '__new__', '__radd__', '__reduce__', '__reduce_ex__', '__repr__', '__rsub__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__sub__', '__subclasshook__']

但是，我不知道如何构建一个新的。它们看起来非常有用，我想更多地使用它们。

我试过导入间隔模块（Runtime error (ImportException): No module named interval）。我尝试将列表投射到 Interval: Interval([1,2])→ Runtime error (UnboundNameException): name 'Interval' is not defined。

我不知道区间是属于 Python、Iron Python 还是蚱蜢。

如何创建新的间隔？

在一些帮助下，我最终得到了：

print "x is sent in as a domain from the input to this function"
print x, type(x)
print x.GetType().FullName
print x.GetType().Assembly.Location

print "\nThere seem to be two types of intervals, Rhino and grasshopper. Now sure why you'd use a Grasshopper interval, but here it is anyway:"
import Grasshopper as gh
y = gh.Kernel.Types.GH_Interval()
print y, type(y)
print y.GetType().FullName
print y.GetType().Assembly.Location

print "\nTo make a Rhino interval get it from the Rhino.Geometry module"
import Rhino.Geometry.Interval as interval
z = interval(0,1)
print z, type(z)
print z.GetType().FullName
print z.GetType().Assembly.Location

print "\nz is the same as x:", z == x

这使：

x is sent in as a domain from the input to this function
0,1 <type 'Interval'>
Rhino.Geometry.Interval
C:\Program Files\Rhinoceros 5 (64-bit)\System\RhinoCommon.dll

There seem to be two types of intervals, Rhino and grasshopper. Now sure why you'd use a Grasshopper interval, but here it is anyway:
0.0 To 0.0 <type 'GH_Interval'>
Grasshopper.Kernel.Types.GH_Interval
C:\Program Files\Common Files\McNeel\Rhinoceros\5.0\Plug-ins\Grasshopper (b45a29b1-4343-4035-989e-044e8580d9cf)\0.9.76.0\Grasshopper.dll

To make a Rhino interval get it from the Rhino.Geometry module
0,1 <type 'Interval'>
Rhino.Geometry.Interval
C:\Program Files\Rhinoceros 5 (64-bit)\System\RhinoCommon.dll

z is the same as x: True

如果我们将其解包： IronPython 的type() 函数实际上返回一个包装 .NET 类型的 PythonType。.GetType() 直接获取 .NET 类型。所以type(x)给出<type 'Interval'>的不是很有帮助，而x.GetType().FullName给出Rhino.Geometry.Interval的却是告诉我如何获得它。

此处的Rhino 文档对此进行了介绍，它具有许多有用的属性和方法。
