Member Typedef Documentation
| typedef DT ml::Tvec4< DT >::ComponentType |
A typedef to "export" the type of components.
Reimplemented from ml::FloatingPointVector< DT, 4 >.
Definition at line 63 of file mlVector4.h.
| typedef FloatingPointVector<DT,4> ml::Tvec4< DT >::Superclass |
A typedef as a shorthand for the base class.
Definition at line 60 of file mlVector4.h.
Constructor & Destructor Documentation
Default and value constructor. Set all entries to a user given value.
Definition at line 70 of file mlVector4.h.
| ml::Tvec4< DT >::Tvec4 | ( | const Superclass & | v | ) | [inline] |
Copy constructor from FloatingPointVector.
This allows the usage of SclarVectorTemplate objects of the same DT in operators using the Tvec4, because the FloatingPointVector objects can implicitly be cast.

| ml::Tvec4< DT >::Tvec4 | ( | const DT | x, |
| const DT | y, | ||
| const DT | z, | ||
| const DT | w | ||
| ) | [inline] |
Build the vector from the scalars x, y, z and w to the components 0 to 3, respectively.

| ml::Tvec4< DT >::Tvec4 | ( | const Tvec2< DT > & | v, |
| const DT | z, | ||
| const DT | w | ||
| ) | [inline] |
Cast Vector2 to Tvec4. Set last two entries are given by z and w.
Definition at line 96 of file mlVector4.h.
Cast Vector3 to Tvec4. Set last entry to the passed value w.

Member Function Documentation
| void ml::Tvec4< DT >::assign | ( | const DT | x, |
| const DT | y, | ||
| const DT | z, | ||
| const DT | c | ||
| ) | [inline] |
Set all components to the passed values.
Definition at line 118 of file mlVector4.h.
Divide all vector components by its last component and return it as Tvec4 which then has a 1 as last component.
It is useful to scale the vector from homogeneous space to normal space. It's up to the caller to avoid a division by zero if last component is 0.
