Shaderをレイヤーで合わせることができるから、ちょっと面白いかも。
とりあえず、繰り返し処理はfor文を使う。

#box_check.pyg

Output ("box_check.tif", "tiff", "rgb", "camera", "float gain", 1, "float gamma",

 1, "string filter", "gaussian", "float[2] filterwidth", (2, 2))

Attribute ("float shadingquality",1.2)

Attribute ("string projection", "perspective")

Attribute ("float fov", 20)

Attribute ("int[2] resolution", (640, 480))

#placecam 10 5 -10 0 0 0

Rotate (-19.47, 1.00, 0.00, 0.00)

Rotate (45.00, 0.00, 1.00, 0.00)

Translate (-10.00, -5.00, 10.00)



#Attribute ( "int ray:shadows", 0 )

Attribute ("string geometryset", "+shadows")

Attribute ("string geometryset", "+reflection")



World ()

Light ("light1", "pointlight", "float intensity", 400, "point from", (-10, 10, -10),"string shadowname", "shadows")

Light ("light2", "pointlight", "float intensity", 400, "point from", (10, 10, -10),"string shadowname", "shadows")



PushTransform ()

Attribute ("color C", (0.2, 0.4, 0.75))

Sphere (100, -100, 100, 360)

PopTransform ()



for i in range(5):

    PushTransform ()

    Attribute ("color C", (1, 1, 1))

    Shader ( "surface", "metal","string envname","reflection" )

    #Shader ("surface", "plastic")

    i=1.2*i

    Translate ( 0, 0.5, i-2)

    Input ("BoxGeom.rib")

    PopTransform ()





Attribute ("color C", (1, 1, 1))

Rotate (90.00, 1.00, 0.00, 0.00)

ShaderGroupBegin ()

Shader ("surface", "checker","layer1","float stilesize", .1, "float ttilesize", .1)

Shader ("surface", "plastic", "layer2")

ConnectShaders ("layer1", "Cout", "layer2", "C")

ShaderGroupEnd ()

Input("PlaneGeom.rib")
