Hello,
I'm traying to turn this torus like a bridge, but the code that I used
doesn't work right. What's the problem?
====================================
difference {
torus { .3, .1 } plane { z, 0 rotate y*90} texture { T_Gold_1D } finish {
specular 1 ambient 0.9 reflection .001 phong 0.3 phong_size 30 }
scale 0.7 scale <1.5, 1, 9> translate <3, 2, 0> rotate <90, 180, 0>
translate y*2*sin(1*2/1*9*pi)*cos(1*0.5/0.9*2*pi)}
====================================
I tray it with the translate "y*2*sin(1*2/1*9*pi)*cos(1*0.5/0.9*2*pi)"
Thanks in advance,
Oleguer

You should be more specific about what you are trying to do. That
description is not clear enough to know.

Well I want to turn the torus like a bridge. In the middle of it. I'm
thinking how can I do it...
Warp, can you tell me where are you from? I put on my web page the people
who are helpping me to make the pictures. What's the right verb: make or do?
Thanks,
Oleguer

Well, I'm sorry, maybe is my English...
I want to double the torus. I want make an angle in the middle of the torus
like a bridge. For exemple: if the torus has 4cm I want to make an angle of
45º in the middle of it (2 cm).
Can you tell me where are you from please? In that way I can put you in my
web page on the gratitudes. I like to put all the people who are helpping me
to do the pictures.

I think that I have to do a macro...
I trayed with it:
======================================
#local YPos = y*9*sin(1*4/5*9*pi)*cos(1*0.5/6*2*pi);
#local XPos = (1+2*2);
#local ZPos = (1+0.5*1);
======================================
I'm going to do a macro.

Well... It isn't correct. I'm thinking...
=============================
difference {
torus { .3, .1 } plane { z, 0 rotate y*90} texture { T_Gold_1D } finish {
specular 1 ambient 0.9 reflection .001 phong 0.3 phong_size 30 }
scale 0.7 scale <1.5, 1, 9> translate <3, 2, 0> rotate <90, 180, 0>
#macro MakeMany (Stuff, amplitude)
#while (4 < 6 )
#local YPos = amplitude*sin(1*4/5*9*pi)*cos(1*0.5/6*2*pi);
#local XPos = (1+2*2);
#local ZPos = (1+0.5*1);
object {
Stuff
translate <xPos, yPos, zPos>
rotate 29*x
}
#local 0.5 = 0.5 + 1;
#end
#local 4 = 4 + 1;
#end
}
#declare amplitude = 40;

I have absolutely no idea what you're doing with this. It is certainly
making the problem far more difficult than it needs to be. (For example,
your XPos is just 5, and ZPos 1.5. I haven't a clue what YPos is
supposed to be.)
Are you trying to fold a torus? What kind of bridge is it supposed to be
like? What part has a 45 degree angle? Is 4cm a minor or major radius,
or something else? What about the middle of it?
You need to give more information about what you want. Repeating the
same vague description and apparently random bits of code won't work, no
matter how good your English is.

Ok Christpher,
Well, I want to double or fold (I think the verbs are corrects) this torus
in the middle of it to make an angle of 45º.
The idea is like a bridge, the bridges make an angle in the middle of it of
for exemple 50º.
Maybe now is more clear...
Thank you very much,
Oleguer

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.

I'm sorry for all you who hate international postings here, but I think it's
the only way
Eh! Oleguer! Si no te aclaras con el inglés tienes un grupo internacional
para postear en español sin necesidad de calentarte tanto la cabeza, ni de
calentarsela a los demás. Y por cierto, también me gustaría una respuesta
tuya a mi mensaje sobre los derechos de Autor, que por si no lo habías
captado iba referido a tí.

Are either of these anything like what you are after? Change the "Bend"

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}
}
