Hi everyone,

I'm looking to build a vector pointing in the direction my object is facing; this will be used to move the object in that direction over a time period. I have a 4x4 rotation matrix describing the orientation of the object, and I want to get that orientation as a unit vector (vec3 ideally) from the origin of the object so I can add this times by a deltaTime to simulate a motion. I'm having trouble getting this vector, and also wondering in fact if this is the correct way to go about things. Does have anyone have any thoughts on this?
