Blender from_pydata 从文件读取顶点位置时出错

Blender Python脚本：从文件读取顶点位置的错误处理

python
import bpy

python
# 准备顶点坐标数据
vertices = [
    (0, 0, 0),
    (1, 0, 0),
    (0, 1, 0),
]
# 准备顶点索引数据
faces = [
    (0, 1, 2),
]
# 创建Mesh对象并导入顶点数据
mesh = bpy.data.meshes.new(name="MyMesh")
mesh.from_pydata(vertices, [], faces)

python
file_path = "path/to/your/file.txt"
try:
    with open(file_path, 'r') as file:
        # 读取文件中的顶点数据
        # ...
except FileNotFoundError:
    print(f"Error: File not found - {file_path}")

python
try:
    # 解析文件中的顶点数据
    vertices = [(float(x), float(y), float(z)) for x, y, z in vertex_data]
except ValueError:
    print("Error: Invalid vertex data format")

python
if len(vertices) < 3:
    print("Error: Insufficient vertex data")
