Hey,

I am using the AppGameKit 108beta and I'm trying to work out how to convert the 2D pointer into some 3D coords.

I have a sneaky suspicion that these Get3DVectorXFromScreen, Get3DVectorYFromScreen,Get3DVectorZFromScreen functions hold the key but I've tried a couple of things to convert the normalised result but I just don't have a clue.

I am sure with the other commands available there is a way to achieve this but I just can't think how. Again my sneaking suspicion is it may have something to do with the FOV, Screen Width & Height and the direction we are looking in.

Has anyone managed this either with AppGameKit or another language?

Cheers,

Alasdair

Here is an example of how to use these commands



The * 10 part will mean that the object will be placed ten units in front of the camera at the pointer position.
