Re: Apply Mutating Algorithms

[Daniele C. <dca...@in...>]

The error prompt is:
 Expression: vector subscript out the range
The problem is when there is a trimesh and edges are not definite.
I modify function MergeTrimeshList , I add
if(tmData.edges>0)
    AppendArrayToVec(... ... ...)

It seem work fine.
