我正在尝试使用python编辑povray文件中的单行.
该文件如下所示:
camera {
angle 38
location <500,0,0>
right x*image_width/image_height
look_at <0,0,0>
rotate <0,0,0>
}

我想编辑文件中描述的变量,所以它出现如下:
camera {
angle 38
location <1000,1000,1000>
right x*image_width/image_height
look_at <10,10,10>
rotate <30,30,30>
}

为此,我使用以下方法:
def updateCamera(self, filename):
tmp = "povrayContent/temp.pov"
lines = open(filename, 'r')
out = open(tmp , 'w')
for line in lines:
if " angle" in line:
out.write(" angle "+str(int(self.camAngle))+"\n")
elif " location" in line:
out.write(" location <"+str(int(self.camera[0]))+","+str(int(self.camera[1]))+","+str(int(self.camera[2]))+">\n")
elif " look_at" in line:
out.write(" look_at <"+str(int(self.camera[3]))+","+str(int(self.camera[4]))+","+str(int(self.camera[5]))+">\n")
elif "rotate" in line:
out.write(" rotate <"+str(int(self.camera[6]))+","+str(int(self.camera[7]))+","+str(int(self.camera[8]))+">\n")
else:
out.write(line)
shutil.copy(tmp, filename)

编辑:相机是一个元组,包含变量应更改为的新值.在大多数情况下,这似乎有效.唯一的问题是在摄像机声明之后,场景中有大约40k行的其他对象声明.我遇到的问题是新文件中缺少最后20行左右的声明.有谁知道发生了什么,是否有一些我不知道的python限制?
