[IronPython] WPF 3D: Missing Viewport3D when importing

[walgri]

Hello,

I have some Python experience, but I'm very new to .Net/WPF programming.
I find that Media3D is missing Viewport3D in 2.0A3:

In Ipy 1.1, with previous import of avalon.py, Viewport3D is still
missing, but is actually avaliable:

Actually the following code works if I cut and paste it in an Ipy 1.1
session, but fails as a standalone app:

###for IronPython 1.1:
#from avalon import *

### for IronPython 2.0A3:
import clr
clr.AddReferenceByPartialName("PresentationCore")
clr.AddReferenceByPartialName("PresentationFramework")

from System.Windows import *
from System.Windows.Media import *
from System.Windows.Media.Media3D import *

w=Window()
v=Viewport3D()

cam = PerspectiveCamera()
cam.FarPlaneDistance = 100
cam.LookDirection = Vector3D(-11,-10,-9)
cam.UpDirection = Vector3D(0,0,1)
cam.NearPlaneDistance = 1
cam.Position = Point3D(11,10,9)
cam.FieldOfView = 70
v.Camera = cam

triangleMesh = MeshGeometry3D()
point0 = Point3D(0, 0, 0)
point1 = Point3D(5, 0, 0)
point2 = Point3D(0, 0, 5)
triangleMesh.Positions.Add(point0)
triangleMesh.Positions.Add(point1)
triangleMesh.Positions.Add(point2)
triangleMesh.TriangleIndices.Add(0)
triangleMesh.TriangleIndices.Add(2)
triangleMesh.TriangleIndices.Add(1)
normal = Vector3D(0, 1, 0)
triangleMesh.Normals.Add(normal)
triangleMesh.Normals.Add(normal)
triangleMesh.Normals.Add(normal)
material = DiffuseMaterial(SolidColorBrush(Colors.Lime))
triangleModel = GeometryModel3D(triangleMesh, material)
model = ModelVisual3D()
model.Content = triangleModel
v.Children.Add(model)

#let there be light:
lightmodel = ModelVisual3D()
light = DirectionalLight()
light.Color=Colors.White
light.Direction=Vector3D(-2,-3,-1)
lightmodel.Content = light
v.Children.Add(lightmodel)

#show:
w.Content=v
w.Show()


Any help or advice in getting this code running as an application
would be very appreciated.
Best regards,
Walgri
