Question

我在github中运行了很多示例代码，但是有错误。

代码

from vapory import *

camera = Camera( 'location', [0,2,-3], 'look_at', [0,1,2] )
light = LightSource( [2,4,-3], 'color', [1,1,1] )
sphere = Sphere( [0,1,2], 2, Texture( Pigment( 'color', [1,0,1] )))

scene = Scene( camera, objects= [light, sphere])
scene.render("purple_sphere.png", width=400, height=300)

错误消息

 Traceback (most recent call last):
File "C:\scene1.py", line 60, in <module>

Answer 1

您首先需要安装POV-Ray。有关Windows二进制文件，请参见here。然后，您需要使用POV-RAY安装的实际二进制路径更改config.py中的POVRAY_BINARY变量。

获取POV-RAY可执行文件的路径。
转到C：\ Users \ user_name \ AppData \ Local \ Programs \ Python \ Python37-32 \ Lib \ site- 包\ vapory \ config.py
替换 POVRAY_BINARY = ("povray.exe" if os.name=='nt' else "povray") 与 POVRAY_BINARY = "POV-RAY binary path"

POV-RAY路径类似于： C：\ Program Files \ POV-Ray \ v3.7 \ bin \ pvengine.exe

蒸气错误：FileNotFoundError：[WinError 2]系统找不到指定的文件
