The goal of this workshop is to introduce the new 3D renderer of Processing for Android, A3D. This renderer provides all the basic functionality required for three-dimensional graphics (camera, lights, texturing, etc.), following the API found in earlier versions of Processing. A3D also offers many advanced drawing capabilities on Android devices supporting OpenGL ES 1.1, such as offscreen rendering, Vertex Buffer Objects (VBOs), and 3D text. Level: intermediate to advanced. BYOA is highly recomended.
