world space position relative to camera
Jul 5th, 2007, 9:15pm  
Hey guys, been a while since I've posted anything on the forum, or used P5 for that matter, but I'm nonetheless back!

Anyway, I've been looking around for a way to calculate a position in 3d world space relative to the camera's position and rotation. I know that with screenX/Y/Z() we can do the opposite and get a point on the screen relative to a point in space, and I'm not sure if modelX/Y/Z() can even help here, or if it's been fixed. So I've turned to using the camera's matrix, but I know very little about how to get this data out of that. Digging around has confused me even more.

Is this an easy thing to do? Thanks!

Well I found a work around for this problem if anyone's interest. Using OCD ( http://www.cise.ufl.edu/%7Ekdamkjer/processing/libraries/ocd/ ) I made the cameraX/Y/Z and targetX/Y/Z properties accessible outside of the class by changing private to public on their respective variables declarations inside Camera.java and stitched together a new jar. This gave me access to all the data i needed, and using this should also give me more control over my camera.
