Color index

• Colors <=0 represent a blank voxel
• Colours 1-16 are also represented by colour constants
• Colours 17 and up are repeats of Colours 1-16

The basic colour constants are listed (binary first):

• 00000 : 0x00 : blank
• 00001 : 0x10 : WHITE
• 00010 : 0x02 : GREY
• 00011 : 0x03 : BLACK
• 00100: 0x04 : PEACH
• 00101 : 0x05 : PINK
• 00110 : 0x06 : PURPLE
• 00111 : 0x07 : RED
• 01000: 0x08 : ORANGE
• 01001 : 0x09 : YELLOW
• 01010 : 0x0a : LIGHT GREEN
• 01011 : 0x0b : GREEN
• 01100: 0x0c : DARK BLUE
• 01101 : 0x0d : BLUE
• 01110 : 0x0e : LIGHT BLUE
• 01111 : 0x0f: BROWN
• 10000: 0x10 : DARK BROWN

Returning errors will leave the voxel blank.

The following will return results with +inf/-inf (dividing by 0).

return x/x

Beware: Wrapping a +inf/-inf in a sign() function will return 1 for +inf and -1 for -inf so will change the shape

Steps - positive x down to negative x

return x==y

Steps - negative x down to positive y

return ~x==y-1

Filled steps

return sign(x-y)

Diagonally parallel Bars

return sign(x*y)

Use the following to change the sides of the bars:

return sign(x*-y)

Diagonally parallel 3-cubes

Corner bricks

return sign(x*y*z)

3 voxel side block

return sqrt(x)

Opposing arrows

return x/y/z
