WebJan 20, 2024 · To rotate an image by an arbitrary angle with OpenCV, we need to: Construct a 2D rotation matrix using the cv2.getRotationMatrix2D function; Perform an affine warp using the cv2.warpAffine function, supplying our … WebTurn your 3-vector into a quaternion by adding a zero in the extra dimension. [0,x,y,z]. Now if you multiply by a new quaternion, the vector part of that quaternion will be the axis of one complex rotation, and the scalar part is like the cosine of the rotation around that axis. This is the part you want, for a 3D rotation.

A 3D rotation is defined by an angle and the rotation axis. Suppose we move a point Q given by the coordinates (x, y, z) about the x-axis to a new position given by (x', y,' z'). The x component of the point remains the same. scroll font free
