CGAL三角曲面网格最短路径-断言错误

Question

我正在尝试使用CGAL库的Triangulated Surface Mesh Shortest Paths算法。 我使用以下三角方形情况进行测试：

当我尝试计算任意两个顶点之间的最短距离时，我总是会遇到以下两个错误之一：

错误1：

With ThisWorkbook.Sheets("Sheet2")
'Select this workbook

Dim X As Integer
'I am not sure what I need to Dim this as

.Range("B2").Value = .Range("A2").Value
'B2 is the value I want to autofill down with

X = .Range("A" & .Range("A" & .Rows.Count).End(xlUp).Row).Value - .Range("B2").Value
'X will be the last value in column A


.Range("B2").Select
Selection.AutoFill Destination:=.Range("B2:B" & X + 2), Type:=xlFillDefault
'Not sure what to set my Type as

End With

错误2：

terminate called after throwing an instance of  'CGAL::Assertion_exception'
what():  CGAL ERROR: assertion violation!
Expr: baseOrientation != CGAL::COLLINEAR
File: /usr/local/include/CGAL/Surface_mesh_shortest_path/function_objects.h  
Line: 588

您可以下载最小代码示例，其中包括非格式here的网格。我遵循了CGAL网站上显示的实现。编译需要CGAL和gmp库：

terminate called after throwing an instance of 'CGAL::Assertion_exception'
what():  CGAL ERROR: assertion violation!
Expr: _idx < data_.size()
File: /usr/local/include/CGAL/Surface_mesh/Properties.h
Line: 204

可执行文件需要两个参数：源点和目标点的索引：

g++ main.cpp -lCGAL -lgmp

尝试2和6获得第一个错误，或者0和2获得第二个错误。
