How would you manage to keep a 3d object in the upper right corner of your window or screen, no matter what the resolution is? lets say: always 50 from the upper bound and 50 from the left bound...

Make it a sprite?

It may be more suitable.

Depends on what you are trying to do.

Try this :

Get the 3D Point from these commands (and don't move the camera after this) :

WantedX = Get3DVectorXFromScreen(50,50)
WantedY = Get3DVectorYFromScreen(50,50)
WantedZ = Get3DVectorZFromScreen(50,50)

(you may need to add camera coordinates if not at 0,0,0, as explained is the example in the documentation..)

And multiply the WantedZ coord by the distance (for the wanted size on screen) you want and apply WantedX , WantedY, WantedZ to your object.

Documentation with example : https://www.appgamekit.com/documentation/Reference/3D/Get3DVectorXFromScreen.htm

This worked for me. The code is from Hendron not my own.

@Golelorn, I been trying to get that calculation right for weeks, my code had an offset when a low y value was passed in I gave up and decided to live with it, your (Hendron's) code works perfect, thanks for (re)posting it.
