cylinder = Zylinder
general syntax:
cylinder{<x1,y1,z1>,<x2,y2,z2>, r
texture{ ... ... }
} |
In this <x1,y1,z1> and <x2,y2,z2>
are the coordinates of the centers of the both ends and r is the radius.
|
The examples here:
// the white cylinder left side:
cylinder{ <0,0,0>,<0,3,0>,1
texture{ pigment{ color White}
finish { reflection 0.1 phong 1}
}
scale <1,1,1> rotate<0,0,0> translate<0,0,0>
}
// the both violet cylinders in front:
cylinder{ <2,0,0>,<3.5,2,0>,0.2
texture{ pigment{ color Plum}
finish { phong 1}
}
scale <1,1,1> rotate<0,0,0> translate<0,0,-1>
}
cylinder{ <3.5,2,0>,<5,0,0>,0.2
texture{ pigment{ color Plum}
finish { phong 1}
}
scale <1,1,1> rotate<0,0,0> translate<0,0,-1>
}
// the slice of a tree right:
cylinder{ <0,0,0>,<0,0,0.5>,1
texture{ EMBWood1 scale 0.1
finish { phong 1}}
translate<5,2,3>}
//white flat cylinder, shrinked in z-direction right:
cylinder{ <0,0,0>,<0,0.2,0>,2
texture{ pigment{ color White}
finish { reflection 0.1 phong 1}
}
scale <1,1,0.5> rotate<0,0,0> translate<4,0,2>
}
// the chrome mirrored cylinder in the back:
cylinder{ <0,0,0>,<0,6,0>,2
texture{ Polished_Chrome
finish {reflection 0.7}
}
scale <1,1,1> rotate<0,0,0> translate<3,0,6>
} |

Hint: To construct a cylinder which is parallel to one of the axis of the coordinatensystem but
not in zero position, this can be done in a more difficult way but also in an easier way:
|
The most times worse style:
Start and end point of the cylinder are definded by their final values
=> the length and the position is hard to understand! |
cylinder{<4,2,2>,<4,2,5>,0.5
texture{ ... ... } } |
|
The better style much easier to understand is better done according to this
principle of construction:
1st step: modellizzing (length and radius) the body at zero and then
2nd step: moving the body to it's final position.
In this case the instructions better to understand would be the following:
|
cylinder{<0,0,0>,<0,0,3>,0.5
translate<4,2,2>
texture{ ... ... } } |
|
|
Special Effect: If we add the optional command "open", we get an open cylinder:
|
cylinder{ <0,0,0>, <0,0.35,0>, 0.45 open
texture{ pigment{ color rgb<1,1,1>*0.75}
finish { phong 0.4 reflection 0.05}
} // end of texture
scale <1,1,1> rotate<0,0,0> translate<0,0,0>
} // end of cone ------------------------------ |
