从文本文件编码网格

Question

我想将具有此文本语法结构的 3D 模型编码到 Blender：

<p>
c(255,84,22)
fs(-1)
p(-9,-8,27)
p(-9,-23,27)
p(-7,-24,63)
p(-7,-11,63)
</p>

与创建网格相关的是这些：

<p> 标记一个面部容器（就像在 HTML 中一样）
c标记颜色
p标记顶点坐标（每个面容器最少3个）
</p>标记面的结束
fs:忽略这个

很明显，网格包含很多这些面容器，所以手动创建这个网格真的很浪费时间。我已经编写了一个有效的脚本，但这只提取坐标而不包含面孔。

现在我想实现那些面孔，所以我扩展了脚本，但它不起作用：

faces = [] #Array, where all the vertex Indecies from curFace are stored
verts = [] #Array, where all the vertex coordinates from coords are stored
vertIndex = 0
with open(filepath, 'r') as file:
for line in file:
    if not line.startswith('<p>'):
        continue #Skip lines which don't contain a <p>
    if line.startswith('<p>'):
        curFace = []
        for container in line: #Do a loop while </p> is reached
            if container.startswith('p'):
                coords = container.strip('\np()/ ').split(',') #Remove certain characters and split line into 3 parts (XYZ) 
                coords = list(map(float, coords))
                verts.append(coords) #Send the vertex coordinates from the current face to verts[]
                curFace.append(vertIndex)
                vertIndex += 1
            elif container.startswith('</p>'):
                faces.append(curFace) #Send the vertex Indecies from the current face to faces[] 
                break #Stop the face-for-loop and return to main line-for-loop
            elif not container.startswith('p') or not container.startswith('</p>'):
                continue #Skip lines in the container which don't start with 'p' or '</p>'
mesh.from_pydata(verts,[],faces) #Create the entire mesh with the arrays

P.S.: 这只是主要部分的摘录。控制台没有显示错误。有人可以帮我吗？

如果您的样本数据与您的文件匹配，那么您的循环的基本逻辑就失效了。

您的循环逻辑取决于所有面部数据都在一条线上。

with open(filepath, 'r') as file:
    for line in file:
        # the following is done for each line
        if not line.startswith('<p>'):
            # if the line doesn't start with <p> go to next line
            continue
        if line.startswith('<p>'):
            # if line starts with <p> do the following with 
            # the rest of the line
            curFace = []
            for face in line: # here your are still on the line with <p>
                if line.startswith('p'): # your still on the first line
                    # before this you need to get the next line from the file
                    coords = line.strip('\np()/ ').split(',')
