WebGL support opens up the possibility of developing and running graphical web based application on the i.mx6 within a browser. Furthermore there's also the possibility of the deploying a LAMP stack to serve the application from the i.mx6. This opens up the possibility of developing simple games, kiosk applications, interaction user manuals/instructions and signage displays, etc..
To give you a taste of what is possible with the current WebGL implementation, I've put together a number of short videos that run existing WebGL demos/applications. These were run on lightweight Debian rootfs with Chromium browser (under X) on an i.mx6q board as part of a prototyping exercise. Chromium has been tweaked to maximize performance and the screen resolution was 720p (1280x720. Beware that not all WebGL application will run, some will fail because the Vivante libraries currently lack the 'Float Textures' extensions, others because the GPU is not powerful enough to give a decent FPS rate. Apologies for the quality of the videos. I'd advise that a i.mx6 quad processor is used to run WebGL as the examples consume 25-35% CPU under load.
The first video which also sums up what can be done on the i.mx6 with WebGL is the 'Lego build Chrome' demo. This application allows the creation of a Lego structure.
CopperCube is an editor for creating 3D application, this is the 'Backyard Demo'.
