Hello dear PovRay users.
I use PovRay to generate images sequences of a scene (nothing unusual I guess).
I configured my camera using the "look-at" directive so my object of interest
stay in the middle of the image.
However, as I move my camera (with the "location" vector), the "up" and "right"
vectors changes (automatically) to rotate the camera. I want to print these data
on the debug console.
My question is : how can I read these values ?
I tryied
-------------
camera {
location <A,B,C>
look_at <0,0,0>
#declare cam_top=top;
}
#debug "top = ",cam_top
-------------
but this didn't works.
Can we have access to these "internal" variables to further process it, or do I
have to process everything myself ?
Thank you for any help.
