Overview
This example is a simple 2D Drawing and Animation tool.
Description
You impliment a series of doodles on the drawing pad, and then play the drawings at a configurable frame rate to view the animation.
Requirements
- LabVIEW 2012 (or compatible)
Steps to Implement or Execute Code
- Doodle on the Drawing Pad
- Select Next Frame to create a new frame in the animation
- Repeat instructions i & ii, until you are happy with your creation
- Hit Done
- Watch in amazement as your doodles come to life
- Hit STOP when you grow bored of your creation
Additional Information or References
Front Panel
The tool includes an animation technique called Onion Skinning - when you create a new frame, the drawing pad retains a grayed-out version of the previous frame. This aids the animator in the creation of smoother animations.

Before stopping the application, the user is prompted to save the animation as a series of bitmaps, which can be viewed at a later stage or uploaded to an online gif generator, such as http://gickr.com/ or http://www.gifup.com/
The images will be saved in a sub-folder called Saved Animations inside the application directory.
I would like to work on producing an animated gif directly from LabVIEW, but have been unable to do this so far. If any esteemed members of the community would like to help me, I would be very grateful.
The challenge has been set!!!
I have also attached an example animation, created with the tool, called Fireworks.gif. It is certainly not going to get me a job at Pixar.
To see the animation, just click on the image below.
