GROG (Graphical Display Of Gyroscope) © 2004. I programmed a scientific diagnostic display application for Honeywell Space Systems, an engineering firm. This windows application displays a realtime 3d graphic of rotational data that is transmitted 100 times per second by an ISIS-IMU controller from Inertial Science. An engineer from Honeywell's R&D department created a wireless version of the controller and used my software to test, calibrate and sell the design. Programmed in multithreaded C++ and using openGL for the 3d display, GROG draws a grid and cube, sphere or XYZ axes that track the movement of the controller as it moves around the room. Using advanced hysteresis functionality (for smoother animation), and featuring checksums, realtime serial port stream decoding and very verbose debug logging, this custom scientific research application is even aware of the constant pull of gravity on the controller when it is not moving.
