This screenshot presents early version of the world editor for my nGENE Tech engine. This toolset allows easy edition and creation of 3D worlds.
You can see it in action here i.e. on youtube. At the beginning I'm showing how to create a map very similar to the recently released tech demo and in the later parts present some of the other features.
Here are some technical details:
* editor is developed entirely in .NET 2.0 (C++/CLI)
* I use Weifen Luo's DockPanel control for layout design
* I use nGENE for rendering, physics etc.
When I started developing this editor I thought it'll be much more difficult. However, after some time I realized it's a piece of cake. Even though using C++/CLI it not the best way to go if you care about code readability and quality it makes everything a lot simpler - I had to wrap only some classes (eg. to allow events from engine influence the editor and vice versa) but in general - not much. I believe that if I decided to go with C# I would have much more work with that.
