RIBの出力:

#sp_rect2.py

import sys

import random



while sys.stdin.readline():



    dist = 1

    x = 0.0

    distx = 10.0

    disty = 10.0

    distz = 10.0

    while x <= distx:

        z = 0.0

        while z <= distz:

            y = 0.0

            while y <= disty:

                r = random.random() * .5

                sys.stdout.write("TransformBegin\n")

                sys.stdout.write("Translate " + str(x - 5.0) + " " + str(y - 5.0) + " " + str(z - 5.0) + "\n")

                sys.stdout.write('Sphere [' + str(r) + ' -1 1 360]\n')

                sys.stdout.write("TransformEnd\n")

                y += dist

            z += dist

        x += dist

    sys.stdout.write('\377')

    sys.stdout.flush()

いろいろと調整してみる。実行RIB:

Display "untitled" "framebuffer" "rgb"

Format 640 480 1

Projection "perspective" "fov" 30

ShadingRate 5



LightSource "distantlight" 1 "intensity" 1.5 "from" [0 0 0] "to" [0 0 1]



Translate  0 0 30

Rotate -30 1 0 0

Rotate 20   0 1 0

Scale 1 1 -1



WorldBegin

        TransformBegin

                Surface "plastic" "Ks" 0.6

                Procedural "RunProgram" ["python sp_rect2.py"  ""] [-9.91912 9.91912 -9.91912 9.91912 -9.91912 9.91912]

        TransformEnd

WorldEnd
