RotateImage3d

Applies a rotation of a given angle on a three-dimensional image.

Access to parameter description

This algorithm rotates a 3D image of a user-defined angle $(\theta_x,\theta_y,\theta_z)$ in Euler angles notation.
The new coordinates $(x',y',z')$ can be expressed as a function of the old coordinates $(x,y,z)$: $$ \begin{bmatrix}x'\\y'\\z'\end{bmatrix} = R_x(\theta_x)\cdot R_y(\theta_y)\cdot R_z(\theta_z)\cdot\begin{bmatrix}x\\y\\z\end{bmatrix} $$ where: $$ R_x(\theta)=\begin{bmatrix} 1 & 0 & 0 \\ 0 & \cos\theta & -\sin\theta \\ 0 & \sin\theta & \cos\theta \end{bmatrix} $$ $$ R_y(\theta)=\begin{bmatrix} \cos\theta & 0 & \sin\theta \\ 0 & 1 & 0 \\
\sin\theta & 0 & \cos\theta \end{bmatrix} $$ $$ R_z(\theta)=\begin{bmatrix} \cos\theta & -\sin\theta & 0 \\ \sin\theta & \cos\theta & 0 \\ 0 & 0 & 1 \end{bmatrix} $$ See also
