A rotation matrix is the matrix that rotates a point counterclockwise by a certain angle. This is what the rotation matrix looks like. This rotation matrix simplifies into zeroes and ones for three special angles: 90 degrees, 180 degrees, and 270 degrees. Here are the special rotation matrices...

These classes are Quat, AngAxis, and Matrix3. There are also methods that convert between these classes.The Visualization of Rotation Space The set of all rotations in space may be visualized as:The set of all unit length axis vectors with one endpoint centered at the sphere center (0,0,...
// Set the matrix as column-major for convenient work with OpenGL and rotate by 180 degrees (by negating 1st and 3rd columns) mat[0] = -(1 - 2 * q.y*q.y - 2 * q.z*q.z); mat[4] = 2 * q.x*q.y - 2 * q.z*q.w; mat[8] = -(2 * q.x*q....

You can often obtain the quaternion corresponding to this matrix using the following formulas:However, it could be that the sum of M11, M22, and M33 equals –1, in which case w equals zero (which means the angle is 180 degrees), and the formulas for x, y, and z aren’t valid. In...
Significant effects were found in angle of rotation (p=0.0046; 0 to 180 degrees in a 5-degree increment), target character's distance from the center of rotation (p<0.0001), and target characters (p<0.0001). Issues pertinent in predicting the effect of dot-matrix pattern distortion on ...
