Vista - Text on 3D object

How can I add text to a 3D object? I've tried using VisualBrush etc but can't
seem to make it work (it doesn't display anything). My 3D object is defined
using MeshGeometry3D and then a DiffuseMaterial.

Fixed it! My texture co-ordinates were all wrong. Yo uhave to apply them as
if they were screen co-ordinates i.e. top left corner of the visual brush is
0,0 and bottom right corner is 1,1

You can also do it using a DrawingBrush. DB is a little better performance
wise than VB but they are the slowest brushes.

Live text on 3D can be really slow depending on how much your scene is
changing. If you're never going to change the text, you can use brush
caching
(http://msdn2.microsoft.com/en-us/lib...chinghint.aspx)
or better yet you can render the text to an image with RenderTargetBitmap.

Jordan, the site you mentioned says:

"It does not make as much sense when a TileBrush with static content is
used in a non-static way—for example, when a static DrawingBrush or
VisualBrush is mapped to the surface of a rotating 3D object."

so, CachingHint does help? Text can get really slow when mapped onto 3d.

CachingHint does help. This whole paragraph is really confusing with double
negatives. I believe "it" here refers to the default behavior, i.e. not
cached.

If you have a static VisualBrush or DrawingBrush on 3D, caching it is good.
The only time it would be updated is if the size of the mesh changed in such
a way that you passed one of the size thresholds that you can set.
