= Declination =<br />
<br />
One of the two rotational axes used by the astronomers, and also by [[RT3D]] programmers. Declination is similar to [[Pitch|pitch]]-- if you nod your head "yes," you are rotating in declination. Most [[Engines|engines]] count from +90 to -90 degrees, starting out pointed straight up, turning downwards and ending pointed straight down. Straight forward is 0 degrees. Sometimes mathematicians measure it in radians, a unit of measure that comes from the magical number Pi. A radian equals Pi/180, but most people use degrees instead of radians.<br />
<br />
Astronomers use only two axes (the other axis is [[Azimuth|azimuth]]), because they do not use [[Roll|roll]]. This is similar to the way most [[FPS|FPS]] games work. It is preferred in some RT3D engines because it keeps the [[Viewer|viewer]] level no matter where it points. But this system has a drawback because it suffers from [[GimbalLock|gimbal lock]] whenever the viewer points either straight up or straight down.<br />
