21 gru 2015 · Do we need to subtract the translation vector (t) from matrix M. I think there is no relationship between the 3D vectors of the three axes and the origin. (x_x, x_y, x_z) is a 3D vector that represents only the direction of the X-axis with respect to the coordinate system 1.
If both vectors have unit length, this entry then corresponds to the cosine of the angle between the two basis vectors, hence the name “directional cosine matrix” (sometimes also called “direction cosine matrix”).
Compass point between two locations. Given coordinates of two locations in decimal degrees, this calculator displays constant azimuth, distance and compass points for different compass roses.
You can enter airports, cities, states, countries, or zip codes to find the flying time between any two points. The database uses the great circle distance and the average airspeed of a commercial airliner to figure out how long a typical flight would take.
Since you have the plane (not only the normal vector), a way to find a unique rotation matrix between two coordinate system would be: do the non-unique rotation twice! ##That is. Find an orthogonal vector in the same plane of interest with $A$ and $B$ respectively. Say $A_o \bot A$ in the original plane and $B_o \bot B$ in the target plane.
21 paź 2015 · $\begingroup$ @user3739406 By the rules of matrix multiplication, $0\cdot z + 1\cdot x + 0\cdot y = 3$. More simply, you have the unit $3\times 3$-matrix times a $3$-vector. $\endgroup$ – Graham Kemp
