Yes, of course.

I assume you have drawn 2 views of the torus, one has some perspective, and
one is without perspective (am i wrong?). But still, i don't see what you
want to do.
You are clearly basing you model on a real life bridge (across water?), so
could you find a picture on the internet which shows the type of bridge you
are after?
Greetings,
JWV

The two first pictures are the torus, te first one is like appears on the
POV-Ray without modifications, and the second one I with an angle.
The pictures that are above of the torus, one is a stright line and the
other is the same line with an angle.
I want to do the same with the torus: I have it straight an I want to do an
angle in the middle of it. Just like with the straight line that it converts
like a bridge doing an angle in the middle of it.
I think it's easy to do.

Hi Oleguer,
Your original object cut a torus in two, scaled it (non uniformly) then
rotated it and translated it.
Your drawing ("My Torus - Straight") seems to be scaled uniformly, and cut
differently. Your second drawing ("An angle") seems to me to be the same
shape rotated about 45 degrees towards the camera so the middle looks fatter
because it's closer to the camera.
If that is what you want, then this scene should do it for you:
camera {
location <0.0, 0, -0.8>
look_at <0.0, 0.0, 0.0>
}
light_source { 0 color rgb 1
translate <-30, 30, -30>
}
#declare myBridge = difference {
// Create a torus and move it left of the origin
torus { .3, .04 translate -x*0.1}
// Cut away using a vertical plane rotated by
// 25 degrees around vertical axis
plane { x, 0 rotate y*25}
// Cut away using a second plane rotated by -25
// degrees around the vertical axis
plane { x, 0 rotate -y*25}
pigment {color rgb <1,0,0>}
}
object {myBridge rotate <-90,180,0> }
object {myBridge rotate <-90,135,0> translate x*0.25}
Good luck.

Sorry Oleguer, but it still is not 100% clear to me what it is you want.
Is it the following: I have a torus that lays flat on a table, now I pick
one end up and bend it up? If this, or something simmilar is the case,
then you cant do it with a torus in POV-Ray as non uniform deformations
are not supported.
What you can use though is the spheresweep object. You just have to define
the shape as a spline.

I did an other render and I put it on the binaries.images, I think it can
helps.
I want to do it with the torus, my torus is straight and I want to make an
angle, like on my render.
Tor Olav helpped me to do a render looks like it.

Are either of these anything like what you are after? Change the "Bend"
and "Sharpness" parameters as necessary.

Although it's nothing to do with your question, here's the same thing
with some different values of Bend and Sharpness and a slightly larger
contained_by sphere.
#include "functions.inc"
camera { location <-0, 1, -4> look_at <0, 0.1, 0> angle 40}
background {rgb 1}
light_source {<-100,200,-100> colour rgb 1}
#declare Bend=-0.5;
#declare Sharpness=0.8;
isosurface {
function { f_torus(y+pow(abs(x),Sharpness)*Bend,z,x,0.8,0.15) }
max_gradient 1.5
contained_by{sphere {0,1.5}}
pigment {rgb x}
}
