Re: Outputting Data Onto Computer Screen

As has already been said, you can run notepad as your dashboard if you like. The key is that it listens on the DB port and pulls the data from the data streams. Also said, you don't need to build bitmaps or renderings on the cRIO. Sure, you can do it if you try hard enough, but the fact that the cRIO doesn't have a video card might be a clue that it was designed for something else.

If you are interested in doing OpenGL programming, you can find many frameworks and toolkits to assist you in the language you choose, and yes, the scene graph, sometimes called the 3D Picture Control, will do 3D in LV.

Honestly, I don't think you need OpenGL. LV has a display called the intensity graph which maps a 2D numeric field into color-coded display. It doesn't do contours and fancier stuff, but it does fast display, typically of spectrograms, but other times data from 2D microphone arrays, radio telescopes, etc.
