		Loosely speaking, Yaw measures the camera's left/right position, Pitch measures the camera's up/down position, and Roll measures the degree to which the horizon is tilted.
		Yaw, pitch and/or roll values can be interpolated for multiple images simultaneously, and there are two different interpolation methods.
		After calculating the appropriate roll value for each image, the project is optimized, to calculate the yaw and pitch for each image as well.

	EM300 Yaw Stabilisation
		This is ideal for a sidescan geometry like GLORIA because the yaw stabilisation worked for the far range but failed drastically for the near nadir (which is irrelevant for a sidescan) where a pitch compensation was really required.
		Note also that the yaw example used here was only a +/-1 to 2 degree signal (characteristic of seastates 4 or less) and thus as the seastate worsens the anomalies would grow.
		As expected the peak in yaw distortion occurs in the 500-700m range as the ping period approaches half the wave period.

		Roll is a rotation around the long axis of the fuselage.
		Yaw is a horizontal rotation around the vertical axis of the aircraft, and is initiated by the rudder.
		This yaw means that the wing on the outside of the turn is moving faster through the air, while the inside wing moves slower.

		This can be used to define such things as pointing the payload bay of the shuttle at the earth or orienting the nose of the shuttle to point at a celestial object, like the sun.
		Orbiter attitudes are specified using values for Pitch, Yaw, and Roll.
		These represent a rotation of the shuttle about the Y, Z, and X axes, respectively, to the desired orientation.

	A Spinal Pattern Generating Network Producing Steering through Yaw, Pitch and Roll Movements during Undulatory Swimming (Site not responding. Last check: 2007-10-22)
		Pitch turns are produced through an asymmetry in the activation of the dorsal and the ventral muscles.
		Roll turns are generated when the two oscillators are running out-of-phase, giving rise to a spiral shape of the activation pattern.
		By extending an earlier neuronal network model to incorporate the separate dorsal and ventral outputs we show through simulation experiments that the resulting system is indeed capable of generating activation patterns for yaw, pitch, and roll controlled only by means of asymmetries in the tonic excitatory input.

	Extracting yaw, pitch, roll - GameDev.Net Discussion Forums (Site not responding. Last check: 2007-10-22)
		I can't store a rotation matrix or the three yaw, pitch, roll values for later use since I don't have them at all when I launch the game.
		This is the whole point, I'm trying to figure out a way to calculate yaw, pitch and roll from only these two vectors (one fixed at (0,0,1) and the other read from the file.) With yaw, pitch and roll calculated, I can then easily compute the direction vector that my light needs.
		you could use this, but since yaw pitch and roll are based on a single axis you would have to uses the corrisponding 2d (x,y) (y,z) (x,z) pairs from each vector or whatever.

	Yaw Pitch Roll (Site not responding. Last check: 2007-10-22)
		In humans, turning left or right (yaw, or "heading") is perhaps a more grounded concept than looking down or up (pitch), which is yet more grounded the cocking the head from side to side (roll).
		The remaining one is the one that is less natural as far as head rotation, which is to cock the head from side-to-side, causing the top of the head to move left and right.
		A roll of the head for an Indian (a true Indian, from India) is a non-verbal language gesture that means roughly, "OK".

	ipedia.com: Gimbal lock Article (Site not responding. Last check: 2007-10-22)
		Gimbal lock, in gyroscopicic devices controlled by Euler mechanics or Euler angles, is caused by the alignment of two of the three gimbals together so that one of the rotation references (pitch/yaw/roll, often yaw) is cancelled.
		For example, an airplane uses three references, pitch (angle up/down), yaw (angle left/right on a vertical axis) and roll (angle left/right on the horizontal axis).
		If an airplane heads straight up or down (change of pitch), one other reference (the yaw) is cancelled, one loses a dimension of rotation, because there is always a value for one angle of rotation that yields infinite values of the other two angles (in this case, the yaw).

		The tracking system accurately reports the change in yaw, pitch, and roll of an object as it moves through space.
		Roll, pitch, and yaw are defined as rotations about the XB, YB, and ZB axes respectively.
		Specifically tracking systems which solve for the x,y,z,roll,pitch, and yaw coordinates of an object are referred to as 6 DOF systems.

	MTP Pointing Algorithm
		The roll axis (x-axis) is in the direction of flight, the pitch axis (y-axis) is along the left wing, and the yaw axis (z-axis) is up.
		Armed with these attitude matrices, we are now in a position to determine the instrument yaw, pitch and roll from measurements of the elevation angles of two or more sides of the instrument package.
		Ideally this would be just like the yaw, pitch and roll axes on an aircraft gimbal, involving three axes of rotation in the proper order.

		Yaw means rotation on the Y axis, pitch means rotation on the X axis, and roll means rotation on the Z axis - these are commonly used terms for rotations, so I thought I would use them here.
		After including the C math header and defining a constant for mapping degrees to radians, we declare a texture handle for the floor texture(which will be the checkerboard pattern used in the last lesson).
		There ae class functions for walking forwards and sideways, for crouching, and for adjusting the yaw, pitch, and roll of the camera man. The functions for walking forwards and sideways use cos() and sin() on the camera man's yaw in order to find out which direction forwards and sideways are for the camera man.

		In addition to optimizing the values for yaw, pitch and roll, the Auto-optimizer will estimate the "b" lens parameter to try and correct any pincushion or barrel distortion in the input images.
		Similarly, the yaw for image 2 is +11 degrees, indicating that the camera was rotated 11 degrees to the right when taking this image.
		The pitch values for images 1 and 2 show that the camera was tilted up by 6.4 and 6.3 degrees (negative values indicate pitch upwards), and down by 5.9 and 5.6 degrees for images 3 and 4.

		After running the optimizer, the pano is a mess in the panorama window, I assume that this is because I haven't set my yaw, pitch and roll to the proper amounts.
		If you have a fairly accurate rig, I'd suggest resetting the yaw, pitch and roll of all your images to 0 and just try optimizing from that point.
		If you know the yaw (12 images means it should be near 30 degrees), you could enter starting values for each image, but I'm not sure if this really makes any difference.

		For example, in an airplane's autopilot, the flight plan in the autopilot determines the desired numbers (where to move) that drive everything.
		The direction of the airplane is controlled by ailerons, elevators, rudders, etc. Each mechanical control has a differential equation that takes the desired movement in six different axes (roll, pitch, yaw, forward, back and up), and calculates the control's position.
		Usually each input and output number is filtered for particular oscillations of the aircraft or the control part.

		The rotation is typically measured in reference to one of three axes: yaw, pitch, or roll.
		Depending on how a gyro normally sits, its primary axis of sensitivity can be one of the three axes of motion: yaw, pitch, or roll.
		One of the most important concerns for a gyro user is the device’s ability to reliably provide an accurate angular rate-output signal—even in the presence of environmental shock and vibration.
