other basic function :
scale
+ void scale (const vec3 & p);
scale
+ void scale (float sx,
float sy,
float sz);
rotate
+ void rotate (const vec3 & vect,
float angleRad);
Makes a rotation matrix about an arbitrary axis.
translate
+ void translate (const vec3 & vect);
Makes a translation of the matrix
| Parameter [input]: | vect | Translation to apply. |
coFactor
+ float coFactor (int32_t row,
int32_t col) const;
Computes a cofactor. Used for matrix inversion.
| Parameter [input]: | row | Id of raw. |
Parameter [input]: | col | Id of colomn. |
| Return: | | the coFactorValue. |
determinant
+ float determinant () const;
Computes the determinant of the matrix.
| Return: | | The determinent Value. |
invert
+ Matrix4 invert ();
Inverts the matrix.
Note: The determinant must be != 0, otherwithe the matrix can't be inverted.
| Return: | | The inverted matrix. |
