I have just published a new article which shows a new control that I have made. When I created this control, these were the requirements I had for the control.
- Supports transparency in 3d
- Could pan
- Could zoom
- Supported some of tree like data structure in 3d space
I am pretty pleased with it overall, you can read more about the control over at codeproject : http://www.codeproject.com/KB/WPF/LevelTree3D.aspx
