Here’s a file path to filter out unnecessary data, allowing you to automatically update the file path so your VI will only save data that meets your special criteria.

Do you remember the last time you developed a roll of film and received photo negatives with your pictures? Negatives may seem like a thing of the past, but they are actually the master images from which all other copies are made. Even though there has been an evolution away from film, photographers and amateurs still produce negatives from digital images for use in many photo processes.

Now you can create photo negatives with NI LabVIEW software by using one or all of these functions: IMAQ inverse function, IMAQ subtract, or IMAQ ImageToArray. Each will prompt you to upload an image and then LabVIEW will invert the pixel values and display both the original and the negative image. Isn’t it interesting how we can use modern technology to carry out old processes in new ways?

Community member tjellden created an example program to show off the 3D Picture Control capabilities in LabVIEW. If you run the VI, then you can pull back on the joystick with your mouse and the graphic will update with the aircraft's movement. Needless to say I spent 15 minutes playing with the VI to make the plane do barrel rolls and then I dove into the code to figure out how it was done. I highly suggest checking this Flight Simulator In LabVIEW example out if you are interested in more advanced graphics in LabVIEW.
