I would just use easing.
So you have your current point (x1,y1) and you have where you want to go (x2, y2)

nx = x1 + ((x2 - x1) * ease)
ny = y1 + ((y2 - y1) * ease)

where ease is a value between 0 and 1. So .01 would move very slowly and .9 would move very quickly

add z.

nx = x1 + ((x2 - x1) * ease)
ny = y1 + ((y2 - y1) * ease)
nz = z1 + ((z2 - z1) * ease)

for the rest it depends oon what you try to achieve. if you want to orbit the cam by mouse, or if it should follow the player, or both, if it should avoid obstacles etc. but i doubt you will get presented a full solution. try to figure out what you want to achieve, and what components you need for the solution. then try to solve the components one by one.

Just to clear up confusion, ease is essentially linear interpolation, which is also this:




I think they are functionally equivalent.

you may write it where ease stands, as you may want different values for different directions. go ahead and try.

ease as float
ease = 0.5 // Or any value between 0.01 and 0.99

make sure your x/y/z and/or angle values are floats as well
try it
