Clicking on a button in OPENGL
Oct 24th, 2007, 5:50am  
Hey,

not quite sure where to post this one.

What I'm trying to do is developing an application where the user can navigate in a 3D interface.

For example, you have different paragraphs of text on the screen each at a different z index. Users may zoom in, zoom out the z index read the text that is far away... users can also rotate around them. To do this, is pretty simple.  

My problem is, let's say I want to add a button (probably with a library) below each paragraph and when the user clicks on it calls some function. I tried different libraries but none of them seem to support OPENGL or a z index. If it's a 2D environment, great they work perfectly, but when they're in a 3D world, they don't when where the button has gone to.

Any ideas how I would to this? I'm guessing it's possible since some 3D games offer the possibility of clicking somewhere and reacting to that click.

Any input is very appreciated!
Cheers
