I created this experiment with after effects. There was a lot of tracking involved and a bit of manual tracking. A lot of the animations were done with expressions. I wanted to explore how I can use expressions to control different values. All the numbers signify the tension level of the web as the spider moves though it. I used the value of the layer and subtracted that with the value of the X axis to generate the numbers. As each joint of the web moves on the X axis the numbers change accordingly. As for effects I used: Corner Pin, Holomatrix, Gaussian Blur and Slider Control.
Footage was shot with a 7D at our koi pond.
