Hacking HTML5 canvas to create a stereo 3D renderer

In this article, we present a drawing toolkit developed to create stereoscopic side-by-side 3D stimuli. The toolkit is based in the HTML5 canvas element and drawing is achieved using intermediate stereo scripting methods that correspond to the `2d' context of the canvas. We include performance marks of the toolkit running on desktop and mobile browsers. Also, a discussion of how the tool is used for implementing a stereo 3D UI is specified.
