Radio Detection And Ranging

Radio Detection And Ranging TutorialCollision detection and audio triggering. Learn how to build a radar that actually works using only four keyframes! This one is a must-see!

This tutorial is no different from the others. It’s not creating a certain effect. Oh no. It’s about solving common and uncommon problems, and about finding solutions to situations that might occur in the future. All to help you work more efficiently by saving huge amounts of time. It’s not about the final visual result, but the way to get there.

So… what is this tutorial really about? We’re going to create a radar that really works! Draw the radar, animate the target over it, and watch how the radar detects the object by itself, marks it on the grid and even makes a beeping sound.

This whole project consists of only four keyframes, and few expressions, that will detect the collision between the target and the scanning line. When the collision occurs, the target will become visible, and a beep sound will be generated.

You must see this one! I hope you’ll like it. Enjoy!

Update
There is an update for this tutorial. If you’re using After Effects CS3 than you should check out the CE PixelSampler tutorial, where you can learn how to use my CustomEffect to detect collisions.

  11. Hey Maltaannon great video tutorials! It was good to see some expression work, and it shows that it’s not too difficult to work with expressions,in fact you made using them seem essential. Entertaining too can’t wait to see more.

  14. I observe you for some time and I have to leave at least one comment! I’m pretty amazed by your tutorials. On one side they are very advanced and on the other you present it in a very simple way without any useless steps. Thanks for your “creation”.

    By the way.. it is nice to see some fellow countryman who do his best to pass his wisdom to everyone. CHEERS! AND DO YOUR BEST!

    (another one who came here thanks to videcopilot ;))

  15. Great Tutorial. Love the fact that it is all generated in AE. please keep them coming.

  16. Wow. You’ve got those expressions down. I made a radar a long time ago, with keyframes and it was quite tedious to make a small change- based off of just keyframes. Thank you so much for this expression-oriented tutorial. Have a great day!

  17. Check out the updated version at the end of the CE PixelSampler tutorial. There are no expressions involved, and it still works.

  21. Hi, this is really amazing and very informative tutorial. But i will be thankful if you would kindly tell me the expression that you used on the opacity of the aircraft. thanking you.

    regards

  22. The expression is in the tutorial and in the project file. Like I’ve explained in the tutorial…. it’s hard for me to explain it in Polish, not to mention explaining in English so you’re on your own. Sorry.
