  wiggle and rendering?

  Posted by David Del on April 30, 2009 at 2:38 am

  Does wiggle slow down rendering times? I want to add a slight camera movement, but not if it is going to double or triple my already colossal rendering time…

  wiggle itself won’t cost you anything.

  wiggle is a pure math. Math is easy for the computer.

  “154795421.466845 * 12433.2464 / 0.00054745 – 12” is impossible to compute by human’s brain, but for computer it’s a piece of cake.

  However if your wiggle causes anything that increases rendering time, i.e – motion blur, or anything similiar – well… it will cost you.

  But pure wiggle? No way.

  Let me put it this way: We have 100 frames animation of solid standing still.
  What will be rendered longer: The composition that has 100 position keyframes set to the same value, or the one without any keyframe?

  Answer: The time of rendering will be the same.

  What if you put “wiggle(0,0);”?

  Nothing.

  So let’s put “wiggle(120,50);”

  Any difference? NONE.

  Unless you activate motion blur of-course.

  Calculation of the value of the cartaint parameter caused by wiggle is done before anything time consuming happens. Wiggle only set’s the value. It doesn’t do anything else.
