### Pattern

Patterns are common noise and math functions.
You can easily add them to any shapes.

 Cos:A simple 2D cosine function. (in radian)\$Y*4 + cos(\$X * 400) Scallop Cos:An absolute value of a cos function.\$Y*4 - abs(cos(\$X * 400)) Dot 01:Dots from sin and cos function. \$Y - abs( ( cos(\$X * 400) * sin(\$Z * 400) ) ) / 2 Dot 02:Clamped sin and cos function.\$Y - clamp( ( cos(\$X * 400) * sin(\$Z * 400) ), 0, 1 ) / 2 Cos Circular:cos(360 *((\$X*\$X + \$Z*\$Z)^0.5 ))/(1+\$X*\$X+\$Z*\$Z)- \$Y Sin Circular:sin(360 *((\$X*\$X + \$Z*\$Z)^0.5 ))/(1+\$X*\$X+\$Z*\$Z)- \$Y Random:\$Y + rand(\$X*(\$Y*100)*\$Z) / 4 Noise:\$Y + noise(\$X, \$Y, \$Z) SNoise:\$Y + snoise(\$X, \$Y, \$Z) Turbulence:\$Y + turb(\$X, \$Y*2, \$Z, \$Y+3/2) STurbulence:\$Y + sturb(\$X, \$Y*2, \$Z, \$Y+3/2) Cube Plus Noise:max( max( \$Y*\$Y-1, \$X*\$X-1 ), \$Z*\$Z-1 ) + noise(\$X,\$Y,\$Z) Cube Minus Noise:max( max( \$Y*\$Y-1, \$X*\$X-1 ), \$Z*\$Z-1 ) - noise(\$X,\$Y,\$Z) Noise Cube:(noise(\$X*2, \$Y*2, \$Z*2) -0.1 ) * 2 SNoise Cube:(snoise(\$X*2, \$Y*2, \$Z*2) -0.1 ) * 2 Abs Noise Cube:(abs(noise(\$X*2, \$Y*2, \$Z*2)) -0.1 ) *  2 Abs SNoise Cube:(abs(snoise(\$X*2, \$Y*2, \$Z*2)) -0.1 ) *  2
