RE: [Algorithms] Return of the front clip plane

[Robert D. <RD...@ac...>]

You could just apply real world stuff to it....

look up, you head tilts back, so your eyes will pull away from the wall.

look down, when standing with your nose against a wall and you hit the wall,
so you either collide and can't look down when against a wall or if thats
going to upset people either IK your body so the head is touching the wall,
or move the body back.

either way, in real life you cannot look down with your eyeball touching the
wall, because you aren't built that way, so applying similar limitations in
a game is not unreasonable.

Well this is the same thing as just making the player's collision radius
smaller.  You'd still get too close to the wall and clip it out if you
looked up/down.  Maybe not left/right though, which might be where the
thought came from.  :)

I could just not let the player look up and down, doom got away with it
right?  ;)
