以下是一个简单的 polybool 函数程序的示例:
```python
def polybool(poly1, poly2, operation):
"""
Perform boolean operations (union, intersection, difference, exclusive or) on two polygons.
"""
# Perform boolean operation based on input "operation" string
if operation == 'union':
# Perform union operation by merging vertices and edges of both polygons
result_poly = merge_polygons(poly1, poly2)
elif operation == 'intersection':
# Perform intersection operation by finding overlapping areas of both polygons
result_poly = intersect_polygons(poly1, poly2)
elif operation == 'difference':
# Perform difference operation by subtracting polygon2 from polygon1
result_poly = subtract_polygons(poly1, poly2)
elif operation == 'xor':
# Perform exclusive or operation by finding areas that belong to only one polygon
result_poly = xor_polygons(poly1, poly2)
else:
raise ValueError("Invalid operation. Choose 'union', 'intersection', 'difference', or 'xor'.")
return result_poly
```
上面的 polybool 函数接受两个参数,即两个多边形的顶点和边界,以及一个字符串参数,该参数指示要执行的布尔操作类型。函数根据输入的操作类型,从四种可能的操作类型中选择一种,并返回一个新的多边形结果。
