Hallo,
What is the API for PovRay?
I want to write a small programm to change the cameraposition with buttonclicks
on a window? ( for example : changing from looking from right of the object to
left )
Later I want to have a window with a slider that can change the cameraangle in
X,Y and Z axises
Does somebody has tips about this?
Thank you
ps: I hope you can understand my english , its been long time since i don't use
it.

The simplest way to do this is to generate a POV file and call POVray to
generate an image to use. Look at +I and +O command line options.

I will change it to
You know you've been reading newsgroups too long when...
it's not raytracing specific, even at the slightest

you start thinking up your own "You know you've been raytracing too long

POV is a stand-alone program that can be
invoked from the comand line, not a library
to call from other programs.
It would be easier to calculate a camera
rotation in your own code than to try to
make POV do it for you.
Say for example you have a previously
rendered image 640x480 with a 67.38
degree horizontal viewing angle, and
a 50.54 degree vertical veiwing angle.
Then a click coords on the image (X,Y), this
would mean that the camera could be rotated
to point at that spot...
rotate <(Y/480-0.5)*50.54, (X/640-0.5)*67.38, 0>
all you need to do is keep track of your previous
rotation.
