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.
