Our theme for today is Processing's support for three-dimensional graphics.

To use most of these features, you must explictly use a 3D renderer, indicated with an optional third parameter to the size() function, as in:

size(800, 800, P3D);

Processing tutorial

For background reading, we recommend Danniel Shiffman's P3D tutorial from the Processing website.

For the rest of these notes, we just demo a few of our own sketches.

3D Rotations

This next demo is far more impressive when running directly in Processing rather than through a browser...

Demo: source code

3D Rotations with User Controls
In this version, the user can click and drag to rotate the image along both X and Y axes.
