Here's a thread from mid March 2005 where I made a simple example on how to use a picture control to make a 2D Vector plot (Matlab calls them Quiver plots, other names are Arrow- or Porcupine plots :))

These are quite useful e.g. in fluid mechanics, etc.

I am sure the demo VI could be made in a nice package that does automatic scaling, adds axes, etc. (LabVIEW could actually use something similar as a standard built-in plot type.) 🙂

Just for kicks, I made a little demo that rotates an image in a picture indicator. (...and no, the depicted vase is not for sale ;))

Unclebump posted an example that uses a picture control to represent a dart board.

Is there any way of getting the device context of the picture control, I have been trying for a while of getting a DC and being able to link it to openGL to allow for a full wrapper of the OPENGL32 and GLU dlls in labview.  I understand that Labview 7.1 has added a 3d control but has left 7.0 users in the dust with no support.  I want to make a viewport object for rendering opengl graphics with some events also tied to the object.  I dont want to reinvent the wheel or start a project that I cant handle but would love to join any similar open source efforts if one exists.  Full opengl support in labview would allow for unpreserved visual experiences in labview and push it even more towards a main-stream general programming language.  (I am not a ogl guru but have dabbled in it enough with c++ to get started on a project).  I have seen Ben's posts many times on graphic related issues maybe you know of the current state of 3-d graphics in labview.

Hi Altenbach,

Could you save this rotating picture as 7.0 format??

This thread uses the picture control to develop a guage with a moving scale.

Nice work Uncle!

Here is Christians rotating vase example saved as LV 7.0

Sheldon Stokes shares his LV version of tetris which uses the Pciture control to implement the game screen.

Nice work Sheldon!

Hi Ben,

I might have some time in the next couple of weeks, think I should take the dartboard picture control and make LabDarts??
