Hi,

I'm new and me english is really bad   Sad

I'm doing a software that loads a 3D model (collada with XMLBeans).
In some parts of the scene I need to display text, for this I need the 2d coordinates for the point 3d of the scene.
I'm using perspective projection.

my question is: How do I get the 2D coordinates of one 3D point?

thanks
