Mapping avec warps
Ajuster motifs aux surfaces
Le modificateur de motifs (pattern modifier) "warp" enroule un motiv comme "checker", "brick"
et autres autour de cylindres, sphères, tores et autres objets.
Types de mapping warps: cylindrical,
spherical, toroidal
et planar.
|
Cylindrical Warp
brick sans warp
brick lateral warp
|
Exemple:
pigment { //lateral warp
brick color rgb<1,1,1> // mortar
color rgb<0.8,0.25,0.1> // brick
brick_size <0.085, 0.0625, 1>
mortar 0.01
warp{ cylindrical
orientation <0,0,1>
dist_exp 0
} // end of warp
} // end of pigment -------------------- |
|
brick top warp
|
Exemple:
pigment { // top warp
brick color rgb<1,1,1>
color rgb<0.8,0.25,0.1>
brick_size <0.077, 0.0885, 0.18>
mortar 0.01
warp{ cylindrical
orientation <0,1,0>
dist_exp 0
} // end of warp
} // end of pigment ----------------- |
|
Spherical Warp

Exemple:
pigment {
brick color rgb<1,1,1> // mortar
color rgb<0.8,0.25,0.1> // brick
brick_size <0.2484, 0.0507, 0.125>
mortar 0.008
scale <0.4,1.3,1.1>
warp{ spherical
orientation <0,0,1>
dist_exp 0
} // end of warp
} // end of pigment -------------------- |
|
Toroidal Warp

Exemple:
torus { 1, 0.5
texture{
pigment {
brick color rgb<1,1,1>
color rgb<0.8,0.25,0.1>
brick_size <0.058,0.0525,0.8>
mortar 0.0055
warp { toroidal
orientation <0,0,1>
dist_exp 0
major_radius 0.5
} // end of warp
} // end of pigment
normal {wrinkles 0.75 scale .01}
}}// end of texture and torus ------- |
|
1) Minor Radius Warp
Toroidal Warp
minor radius warp
Click on the image for a higher resolution.
A look inside

Exemple:
torus { 1, 0.5
texture{
pigment {
brick color rgb<1,1,1>
color rgb<0.8,0.25,0.1>
brick_size <1.0,0.0305,0.1>
mortar 0.006
rotate <90,0,0>
warp { toroidal
orientation <1,0,0>
dist_exp 0
major_radius 0.5
} // end of warp
} // end of pigment
normal {wrinkles 0.75 scale .01}
}}// end of texture and torus ------- |
|
Planar Warp
crackle sans warp
crackle avec warp
Click on the images for a higher resolution.
|
This takes a planar image of a 3d texture (from the pane definded by plane normal
in distance along the normal) and extrudes it along the Z-axis like an image_map.
Exemple:
pigment{
crackle scale 0.45
color_map{
[0.0 color rgbf <1,1,1,0.8>]
[0.2 color rgbf <1,1,1,0.5>]
[0.3 color rgb <0.25,0,0>]
[0.7 color rgb <1,0,0>]
[1.0 color rgb <1,0,0>]
}//end of color_map
scale 0.3 translate<0,0,-1>
warp { planar <0,0,-1>, -1
// plane normal,
// distance along the normal
// end of warp
} // end of pigment ------------ |
