What function should i use when i want to set Player's View?

Hi i would like to know what function i should use to set Player’s View just like what the camera tool does.

GM/CalcViewModelView for the viewmodel view (if you want to change that), and

GM/CalcView for the normal view

Also, if you want their view to be different only once they get in vehicles, use

GM/CalcVehicleView, but that gets called at the same time as CalcView anyway
