Matrix
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 |
|---|---|
| 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. |
| translate(point) | Translates the matrix by the point (Point3D). |
| translate(x, y, z=0.0) | Translates the matrix by the x, y, z values. |
| transform(point) | Returns the transformed point (Point3D). |
| 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 |
