How to get Forward vector from camera?

[ErUs]

Whats the correct way todo this?
Do i have to make a vector3df from getVewMatrix[0], [1] and [2] because that seems a bit overkill....

Found it

Code: Select all

vector3df forward = cam->getRotation().rotationToDirection();

[sudi]

but only works when you bind target and rotation i believe.

a save way would be:

Code: Select all

irr::core::vector3df forward = cam->getTarget()-cam->getAbsolutePosition();
forward.normalize();
