Im trying to create a brick texture on a house shaped box but am having trouble:
this is the code for my box (without trying to add brick texture)
box { <-Hx,0,1>,< Hx,Hy,9>
texture { pigment{ color White}
finish { phong 1}
} // end of texture
scale <1,1,1> rotate<0,0,0> translate<0,0,0>
no_shadow
}
and i have been trying to put one of the following examples in
http://www.povray.org/documentation/view/3.6.0/368/
but keep getting declared errors and have no idea what to do, can anyone help?

In your code, you have the following user variables: Hx, Hy, White.
The variable "White" is declared in colors.inc. It's not initialised by
default.
You need to include that file as follow:
#include "colors.inc"
In that file, it's defined as:
#declare White = rgb 1;
If it's the only colour you use, you can add just that #declare to your
code.
Place that line early in your code before you use any colour name.
Hx and Hy are also user variable. You need to explicitely #declare them
before you use them.
#declare Hx = 23;
Keep in mind that anything starting with an UPERCASE character is always
a "user" variable. You may declare it yourself, or have it declared in
some include file.

The hy, hz, and hx are defined sizes, as its a for a house. and the white
statement works, but that is not the issue the whole statement works and brings
a white box, but want i want is to add somewhere in this statement (instead of
white) a brick looking texture but not sure where or what im doing wrong (only
with the brick texture not what i already have)

brick should then replace White in the pigment.
In 2.5.11.5, COLOR_1 and COLOR_2 are place holders. You must supply one
pigment for each. If you don't set these, you get redish bricks with
gray mortar.
Minimal sample:
texture{ pigment{ brick } }
Sample:
texture{ pigment{ brick Aquamarine Firebrick brick_size <7,1,7> mortar 0.1}
finish{diffuse 0.76 ambient 0.02 phong 0.4 phong_size 100}
}

Time ago I made a brick texture based on Philippe texture (sorry, I
didn't remember the original post, it was a nice plane full off pebbles).
// Texture begin here
#declare t_brick_space=texture{
pigment{color rgb <200,90,10>/255}
finish{diffuse .65}
normal{granite .6 scale .4}
}
#declare t_brick=texture{
pigment{color rgb <188,67,8>/255}
finish{
diffuse .7
roughness .15
}
normal{
average
normal_map{
[1.00
boxed 1
poly_wave .3
slope_map{
[0.00 <0,0>]
[0.02 <0,0>]
[0.02 <0,.5>]
[0.6 <1,0>] // Increase or decrease the bump
}
]
[1.00 granite .15 ]
}
}
}
#declare t_wall=texture{
boxed
poly_wave .3
texture_map{
[0.00 t_brick_space]
[0.05 t_brick_space]
[0.05 t_brick]
[1.00 t_brick]
}
warp{planar}
rotate -90*x
scale 0.5
translate <.5,0,.5>
warp{repeat 1.05*x}
warp{repeat 1.05*z offset .5*x}
scale 0.4*z // Change here brick props
#local tseg_Warp_scale=1.3;
scale tseg_Warp_scale
warp{
turbulence <.3,1.5,.3>*.1 //Some turbulence
octaves 4
lambda 1.5
}
scale 1/tseg_Warp_scale
scale 0.3
rotate 90*x
}
// Texture end here
Example:
box{<-2,0,-0.2> <2,2,0.2> texture{t_wall}}
With some adjustments you can obtain something similar to bricks.
