 /*
-qvrot~ - Quaternion-based vector rotation external for Pure Data
+qvtrans~ - Quaternion-based vector transformation external for Pure Data
 2024, Ben Wesch
 
 Functionality:
 - Transforms a 3D vector using quaternion input
 Usage:
-1. Send a 3-channel signal to the left inlet (x, y, z components of vector to be rotated)
-2. Send a 4-channel signal to the right inlet (w, x, y, z components of normalized rotation quaternion)
-3. Receive the resulting 3-channel signal of the rotated vector from the outlet
+1. Send a 3-channel signal to the left inlet (x, y, z components of vector to be transformed)
+2. Send a 4-channel signal to the right inlet (w, x, y, z components of quaternion)
+3. Receive the resulting 3-channel signal of the transformed vector from the outlet
