A Matrix is a 4x4 column-major matrix.

### Attributes

*These attributes are read-only.*

Name | Description |
---|---|

identity | True if the Matrix is an identity Matrix |

### Methods

Name | Description | Added |
---|---|---|

frustum(Rect, near=0.0, far=1.0) | Sets to a frustum | |

getValue(row, col) | Returns the value at the specified row and column. | |

lookat(eye, center, up) | Sets to a look-at matrix from the eye position to the center using the provided up vector. All three arguments are of type Point3D. | |

ortho(Rect, near=-1.0, far=1.0) | Sets to a orthographic matrix | |

perspective(y_fov, aspect, near=0.0, far=1.0) | Sets to a perspective matrix | |

rotate(angle, axis=None) | Rotates the matrix around the axis (Point3D) or origin by the angle (radians). | |

scale(point) | Scales the matrix by the point (Point3D). | |

scale(x, y, z=1.0) | Scales the matrix by the x, y, z values. | |

setValue(row, col, value) | Sets the value at the specified row and column. | |

shear(point) | Shears the matrix by the point (Point3D). | |

shear(x, y, z=0.0) | Shears the matrix by the x, y, z values. | |

transform(point) | Returns the transformed point (Point3D). | |

translate(point) | Translates the matrix by the point (Point3D). | |

translate(x, y, z=0.0) | Translates the matrix by the x, y, z values. | |

transpose() | Returns the transposed matrix. | 6.0 |

viewport(Rect, near=0.0, far=1.0) | Sets to a viewport |

### Math Operators

Operator | Argument | Description |
---|---|---|

* | Point3D | Transforms the Point |

* | Matrix | Concatenates the Matrix |

- | Returns the inverted Matrix | |

! | 1 if the Matrix is identity, 0 otherwise |
