MotionSpray is a drawing application based on motion tracking.
It allows you to draw shapes based on the detected movements of the device.
The application includes the following features :
* OpenGL 3D Drawing with customizable options (brushes, colors, ...)
* Motion tracking and error correction
* Augmented Reality drawing

OpenGL drawing :
Select between different types of brushes, choose a stroke size, and customize
the color of your brushes in order to give a lighting cool effect to your
drawings.
Use the Transform menu to rotate and move the rendered shapes.

Motion tracking and error correction :
Every recorded accelerations are analysed and corrected in order to find
the more precise shape.
It is actually well known that the accelerometer values lacks in accuracy due
to error accumulation and to the absence of a gyroscope on 3G and 3GS devices.
MotionSpray tries to compensate this lack using an Error Reduction Algorithm.

Augmented Reality drawings:
The drawings you perform are rendered over the camera view of the iPhone.
Once you decide it, you can save your drawing by taking a picture, and store it in your Photo Album.
