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...
What is the Rule for a 90-Degree Rotation Matrix? If we want to rotate a vector given by (x, y) by 90 degrees in the counter-clockwise direction using the rotation matrix then the new coordinates are given as (-y, x). What are the Properties of the Rotation Matrix? The determinant...

an original picture, obtaining a picture rotated clockwise by 90 degrees by changing the bit arranging order for each row of the transposition matrix, and then obtaining a picture rotated counterclockwise by 90 degrees by changing the bit arranging order of each column of the transposition matrix...
is given by the following matrix: Rotation about z axis is: Rz = cos(a) -sin(a) 0 sin(a) cos(a) 0 0 0 1 For example if we choose an angle of +90 degrees we get 0 -1 0 1 0 0 0 0 1 the direction of rotation is given by the right hand rule where the thumb is in...
Matrix RolloutThese settings control how secondary vectors of the orientation matrix will be derived (the up vector is the main alignment vector, and the right vector is derived from the cross product between the up and forward vectors).Forward Vector:...
