I'm currently on a laptop.
my pc will be upgraded with a new motherboard and a new case on tuesday.
No reinstallations needed
so I just got a reply from someone on my youtube who knows how to get the 3D coordinates and how to convert them to X and Y data.
the requirements will be pixel shader 3.0 for a video card though
It's possible with PS 2.0 but PS 3.0 makes it alot easier.
In other words:
I found the right way to convert an XNA 3D game to a laser projector.
The thing is that it still needs to be made, and thats what I'm going to do soon
Happy new year everyone,
Pieter
