RotationX, RotationY, RotationZ

Syntax

Parameters

angle

Rotation angle.

pDst

Pointer to the rotation matrix dst.

Description

The functions ippmRotationX_m4_32f, ippmRotationY_m4_32f, and ippmRotationZ_m4_32f are declared in the ippm.h file. These functions compute the 4x4 rotation matrix for the given angle, as follows:

• For the x axis,

           | 1       0           0       0 |

     dst = | 0   cos(angle)  sin(angle)  0 |

           | 0  -sin(angle)  cos(angle)  0 |

           | 0       0           0       1 |

• For the y axis,

           | cos(angle)  0  -sin(angle)  0 |

     dst = |     0       1       0       0 |

           | sin(angle)  0   cos(angle)  0 |

           |     0       0       0       1 |

• For the z axis,

           |  cos(angle)  sin(angle)  0  0 |

     dst = | -sin(angle)  cos(angle)  0  0 |

           |      0           0       1  0 |

           |      0           0       0  1 |

The ippmRotationX_m4_32f, ippmRotationY_m4_32f, and ippmRotationZ_m4_32f functions compute the matrix for the rotation around the x, y, and z axes, respectively.
