February CTP Samples for 3D - None of it works

I'm trying to follow along through the "How To Topics" in the 3-D
section of the WPF documentation using the online Windows SDK
documentation. Of course, not a single one of these samples actually
works, nor do the 3-d samples in the downloaded samples that came with
the SDK.

I've managed to figure out a couple things, like "Up" has changed to
"UpDirection" and "LookAt" has changed to "LookDirection" for the
PerspectiveCamera, but one thing that doesn't seem to work at all is no
value supplied for TriangleIndices is working properly.

Can someone please supply some XAML that just drops a 3-d sphere onto a
view port and renders it, or possibly a MeshGeometry3D that actually
works?

I would greatly appreciate it.

Thanks,
Kevin

You could take a look at my HelloWorld3D sample.
A sphere isn't just 3 lines of code... so start with a single triangle

Kevin,

It looks like you've been having a frustrating experience with the February
CTP documentation for 3D.

You're quite right that several of the "How Do I?" documents contain code
snippets that are outdated. Ideally, those code excerpts are linked to
tested samples; when the samples are updated, the excerpts should be updated
too. I didn't catch these particular linking errors in time for the February
release. I know stuff like this costs people time and energy, so please
accept my apologies--hopefully the enclosed code samples will help resolve
your difficulties.

Since you asked about spheres and cubes in other posts, I've enclosed a
couple of projects that include those meshes. I successfully ran these
against the February CTP. Though it looks like you resolved your question
about camera rotation, the samples also include animated rotations. If I can
help resolve problems with SDK samples, please let me know either on the
newgroup or directly.

I recognize that some of the SDK's samples don't yet reflect all the
scenarios that advanced users want. We're working hard to improve our sample
coverage and overview articles in upcoming releases. In the meantime,
several developers and evangelists here are blogging great information about
3D--Tim Sneath (http://blogs.msdn.com/tims/default.aspx) and Daniel
Lehenbauer (http://blogs.msdn.com/danlehen/default.aspx) in particular.
