Having trouble finding a starting point (MeshSimplify)

[roussec]

Hi,

I know the progressive mesh functionalty from D3DX 8/9. Unfortunately it is gone in DX10/11/12.

I am exited to possibly have it back with this library. However I am having trouble finding a starting point with MeshSimpify. When passing a mesh from the samples (e.g. mechpart.recon.m -numpts 40000 -nf 20000 -simp -prog mesh.prog -nf 500 -simp >mechpart.base.m) I am getting a file exception (RFile looks for '-' or a gzip extension).

My goal is to use the functions the library provides to simplify meshes based on our internal mesh structure (vertices with position, normal, color). How do I build a Mesh (GMesh) from vertices? I can only see a method that parses a mesh from text/stream.

Thank you.

Please be more precise about the problem. Are you able to run the demos?
Yes. the GMesh class (in libHh/GMesh.h) (derived from Mesh) lets you create vertices and faces, and attach string attributes.

Thank you for your quick answer. Can you please provide an example how to create a GMesh from code. E.g. having a list of triangles with vertices (positions, normals, colors).

I am able to run the compiled samples but I am for example not able to run MeshSimplify from Visual Studio with Debug Command Arguments. This gives me an exception in RFile::RFile(). However I am more interested to construct a mesh from our data structures.

Thank you.
