Hi all,

I have not grasped how POVRay work truely, so maybe my question be a stupid one.

I have imported a 3D mesh in OBJ format into povray, but when I render it, it
seems just like a perspecive scene of the object, whic I'm not able to rotate
it. I don't know even if this (i.e. roatating objects)is possible or not in
povray!


Thanks

Vincent

   Everything is "a scene" in POV-Ray! It is not an object viewer, and is
not real-time. It is a classic raytracer, so maybe you are looking at
the wrong program for your purposes...

If I understand what you want to do, you need a modeller like Wings3D or 
Blender to manipulate your object.

Jamie has suggested that PovRay might not be suitable for your needs and this
could be true.
But if you really want to use PovRay then you need to use the rotate command in
the SDL script. Look at the help, section 2.2.7.1.3 Rotate.
If you want to create an animation of your mesh rotating you will need something
like:

mesh2 {
[snip]
   pigment {rgb 1}

rotate <0, 360 *clock, 0> */ rotates the mesh 360 degrees around the Y axis for
a cycle of the clock going from 0.0 to 1.0 /*
}

You might want to read the animation section in the manual and look at a couple
of the example files. To get the hang of animations it would be better to
replace your mesh with a cube to speed things up.
When you have finished you will have a series of files and you will need video
encoding software to build an animation.  You can find some links here:

Does this answer your question?

Woww..thanks for the responses to this stupud question.
Actually, what I'm looking for is that, with a preset light source and camera,
what heppens to light reflectance of the object when it is rotated or moved(the
object includes some pores- and I don't want to create animation).
Considering your explanations, it seems that it means a real time raytracing,
and if I want to do that in povray I just can have a scene at each position.

In this case what softwares (Proprietary/ Freeware/...) do you suggest?  Thomas
suggested Wings3D or Blender, any others are welcomed.

Thanks!

Vincent
