Looking for XNA/SlimDX/OpenGL advice for 3D component in program

04 February 2012 - 05:45 PM

I've been working on a custom GPS Guidance program for our farm tractors. I'd like to incorporate a coverage map (a map to show what part of the field is finished) on my windows forms project. Something as shown in the following links.

I started with Visual Basic 2010 but just now finished converting it to Visual C# 2010 as it seems there are very few tutorials for VB.net (a couple XNA 4 tutorials) and I got tired of running into problems while converting to VB. This software most likely will only run on Windows 7 computers, most of which will be touch screen tablets. I am developing on my desktop computer and testing with my touchscreen laptop. SlimDX and XNA works on both. In regards to OpenGL, my laptop only supports 2.x, my desktop supports 4.x and the win7 tablets out there right now appear to support up to 3.x. I'd expect OpenGL 2 should be sufficient for this but I don't really know.

Some things I've observed from the XNA and SlimDX tutorials that I have tried is that I could use something like a PictureBox's handle for the OutputHandle. Also I'm thinking it needs to be a 3D perspective is for easy zoom, tilt and rotation control. That way I could always draw to a set coordinate system (related to GPS lat/long) and just change the camera/perspective parameters.

Another aspect to this part of my project that could determine which platform I use is whether all of my logged position points have to be loaded into the graphics engine at each refresh or just the new position points. IIRC I read that some methods clear the back buffer before redrawing the content and switching with the front buffer. In my application I think I will mostly be adding to the existing rendered view.

I also would like coverage overlap to show up darker.

I have read several forums threads/topics on comparing various graphics engines but I still don't know enough to understand which graphics engine would make my work easier. I'm hoping someone with more experience than mine can steer me in the right direction. Please ask questions if what I've typed needs further explaining or if you need to know more information to properly advise me.

Thanks.
