我在 github 中运行了汽化的示例代码，但它有错误。

  • 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)

  • 错误信息

您首先需要安装 POV-Ray。有关 Windows 二进制文件，请参见此处。然后，您需要将 config.py 中的 POVRAY_BINARY 变量更改为 POV-RAY 安装的实际二进制路径。

  1. 获取 POV-RAY 可执行文件的路径。

  2. 转到 C:\Users\user_name\AppData\Local\Programs\Python\Python37-32\Lib\site-packages\vapory\config.py

  3. 替换 POVRAY_BINARY = ("povray.exe" if os.name=='nt' else "povray") 为 POVRAY_BINARY = "POV-RAY binary path"

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

对于 Windows 7，POV-Ray 二进制文件的路径应使用“/”而不是“”，如下所示：

POVRAY_BINARY = "C:/Program Files/POV-Ray/v3.7/bin/pvengine.exe"
