Title: calculating "straight line" velocity
Hello peeps,
I'm currently doing some camera moves that will eventually end up motion control and am trying to calculate the velocity and accleration of the camera. With the global kinematic velocity and acceleration i get x y and z as seperate componetnts but i've no idea what to do mathwise to combine these numbers to get velocity in a "straight line" as in "camera doing 8 metres/second". I initially thought that i would just invert any negative numbers, add the three together and divide by 3 ( i can hear some of you laughing) but it didn't take very long before i realised it was beyond my mathmatical capabilities. Is it an easy equation that someone could explain or am i limited to doing it graphically (which will only give me velocity)?
I spent too long behind the bike shed at school clearly....
