①Pythonで画像から色情報抜き出す
(1)画像を準備(縦横400pixcel（マス目は40x40）)

(2)Pythonで色情報を抜き出す

out_img.py

#coding: utf-8

from PIL import Image

im = Image.open("./400x400.jpg")
rgb_im = im.convert('RGB')

f = open('./Ein400x400.txt', 'w')

for i in range(5,401,10):
    f.write("(\n")
    for j in range(5,401,10):
        r, g, b = rgb_im.getpixel((i, j))
        f.write("("+str(((i/5)+1)/2) +"," + str(((j/5)+1)/2) + "," + str(r) + "),\n")
    f.write("),\n")

f.close()

②PythonでShade3Dスクリプトで濃淡絵を書く
(1)スクリプト

script_for_shade3d.py

import math
import random
scene = xshade.scene()
scene.begin_creating()

a = ((
(1,1,66),
(1,2,64),

〜略

(40,39,130),
(40,40,120),
),
)

for n in range(0,40,1):
	for m in range(0,40,1):

		s = 0.5
		x = n
		y = 0
		z = m
		hgt = 8 - a[n][m][2] * 8 / 255 

		scene.create_primitive_box(None, 3, True, 1, 1, 1, [x+s, y-s, z-s], [x+s, y-s, z+s], [x-s,y-s, z+s], [x-s, y-s, z-s], [0, 2+hgt, 0], True, True)

scene.end_creating()

(2)Shade3D
