|
From the source for slip_skid_ball.cxx, the number returned is (-z_accel/y_accel)*10.
|
|
For small theta, theta~=tan(theta) when theta is in radians. So the angle of a "ball"
|
|
undergoing z_accel and y_accel hung on the end of a string makes with the verticle
|
|
will be approximately -z_accel/y_accel radians. Converting to degrees, multiply by
|
|
180/pi=57.29, or 5.729 times the returned value. Edited by Dave Perry, 2/26/06.
