vcglib | vcglib mirror -

In the Visualization and Computer Graphics Library (VCG for short), there's a concept as wedge.
For example, vcg::face::WedgeTexCoord and vcg::face::WedgeColor. What does wedge mean?

I have a CGAL surface_mesh of triangles with some self-intersecting triangles which I'm trying to remove to create a continuous 2-manifold shell, ultimately for printing.

I've attempted to use remove_self_intersection() and autorefine_and_remove_self_intersections() from this answer. The first only removes a few self-intersections while the second completely removes my mesh.

So, I'm trying my own approach - I'm finding the self-intersections and then attempting to delete them. I've tried using the low level remove_face but the borders are not detectable afterwards so I'm unable to fill the resulting holes. This answer refers to using the higher level Euler remove_face but this method, and make_hole seem to discard my mesh entirely.

Here is an extract (I'm using break to see if I can get at least one triangle removed, and I'm just trying with the first of the pair):

Meshlab uses vcglib c++ library at its core. I was wondering if Meshlab can check if a point is inside a 3D mesh (polyhedron). I found an article which explains a possible way to determine an internal face. However, the proposed method colors vertices based on ambient occlusion, which is dependent on the camera view, and therefore is limited.

Is Meshlab able to use ray casting and get an information for determining if a point is an interior point or not?

I used vcglib to simplify 3D model file. I used the master_a8e87662 git repo. I run the sample trimesh_clustering to simplify a plf file format 3D model with this,

I'm new to VCG and facing some problem with creating a VertexPointer of size 400K+ Vertex. The actual question was asked here in the solution's comment.

I tried to make an array of VertexPointer

MyMesh::VertexPointer vi[400000];

The program crashes with no error in the above line of code.

This is MyMesh Declaration
