I've been using SketchUp as a platform to develop an app that I'm selling. Unfortunately requiring my customers to install SketchUp for $700 is sometimes a deal breaker. I've been exploring other platforms and have ruled out Unity. I spent a few hours this week and did a proof of concept using C#/WPF (shown below). That doesn't seem like the right solution because it only has the ability to draw triangle meshes, no lines. I thought OpenGL might be an option, but I have no experience with it.
Does anyone here have experience with openGL? Would OpenGL be feasible for this? I looked at the Graphis>openGL>fluids example but have no idea where to start. How can I create a simple box model and implement orbit and zoom with mouse?
And the sample project (NOT XOJO - thats why i added the off topic tag)
