Creative coding animation casts a warm light.

The morphing shadow picture.

It's a creative coding animation made with the 'Processing' on Java programming language.

I used the morphing method in 'Morph the Cat'. And I made the animation of shadow pictures feeling.

You can make yet other morphing works by changing 'morphCalc()' parameters. This code does not display any images on the screen but generates image files for animation. You can make an animation with these files.

 

The 'Processing' code example.

Please feel free to use this example code of 'Processing' under the terms of the GPL. To see other works based on my code is my pleasure. And my honor.
