Mapping with Warps
Adapting patterns to surfaces
The pattern modifier "warp" warps patterns like "checker", "brick"
and others around cylinders, spheres, toruses and other objects.
Types of mapping warps: cylindrical,
spherical, toroidal
and planar.
|
Cylindrical Warp
brick without warp
brick lateral warp
|
Example:
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
|
Example:
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
brick without warp

Example:
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 -------------------- |
|

Example:
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

Sample:
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 without warp
crackle with 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.
Example:
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 ------------ |
