  Mouse Movment creates animation

  Posted by Anthony Dupsta on June 18, 2007 at 11:29 pm

  Silly question here.
  I don’t know what to search under so I am asking directly sorry.

  I want to use the movement of my mouse to create animation.

  In Studio Max I can move my mouse around and that movement will translate into spacial keyframes I can apply to an object or null..
  Will AE do this?
  Let me know how if possible.

  Motion Sketch allows you to do this. Window > Motion Sketch. Hit start capture, then drag the layer you want to capture the motion to around in your comp window and it will create keyframes in real-time (you can change this with the Capture Speed setting, higher amounts will result in faster animation).

  However, you can’t do this to 3D layers.

  Hey Thanks. I will mess around with it.
  You say it will not work with 3D layers. So no way I could get this data to work with an AE Camera?

  How do you want to apply the Motion Sketch Data to a camera, seems like an expression to convert Motion Sketch’s x to the camera’s z is possible, do you want to do something like that?

  It would be something like this (Motion Skectch was used on Black Solid 1):

  temp = thisComp.layer(“Black Solid 1”).position;
  [value[0], temp[1],temp[0]]

  This leaves the camera’s x at whatever you set it (value[0]) and makes the camera’s z be the same as the layer that got motion sketch applied (I used a Black Solid 1, it’s x. So the Camera Z now equals the motion sketch x.

  If you want to make the z flight 10 times longer, add a *10 (times 10) to that z temp, the last one in the last line, making this expression:

  temp = thisComp.layer(“Black Solid 1”).position;
  [value[0], temp[1],temp[0]*10]

  temp[1] is the Motion Sketch’s Y value and is what the camera’s Y will be in the expression.

  Or… You could use Motion Sketch on a really large layer to get the flight you want.

  temp [0] is the motion sketch x values, temp[1] is the Motion Sketch Y values. Depending where you put them in the array (I think it’s called), will be the x ,y or z of the camera position.

  Whatta ya wanna do?
