Weights for vertices

[IDIMITRIOUD883D]

How easy is to calculate the weights for the vertices in a T mesh after the insertion process ?

[TrippyLighting]

Since when do vertices have weight?

[IDIMITRIOUD883D]

Sorry. I meant control points!

[TrippyLighting]

When you import a quad mesh, the vertices of the imported mesh become the control point otherwise also called CVs or control vertices. But, again, that pertains only to a quad mesh. that you want to convert into a T-Spline

So suppose  i have a quad mesh, how can i find the assossiated weights?

[TrippyLighting]

Weights, or Vertices ?

[IDIMITRIOUD883D]

i mean weights of control points (xi,yi,zi,wi) . 

[TrippyLighting]

You cannot access those.

Why would you need that ?

Can you provide a graphic example ?

[IDIMITRIOUD883D]

i need them for educational reasons. 

is it possible to export them from a file (stl,step, etc)?

[TrippyLighting · Accepted solution]

.stl files contain only triangular meshes without vertex or face normals or any other attribute. They certainly don't contain weights.

STEP files usually don't contain mesh data.

The vertices in the mesh file formats I am familiar with (.obj .fbx to name a few) as far as I know do not contain any weights.

I don't know if T-Splines carry any weight information on vertices (that is proprietary info) , but if they do,  I know of no way to extract that from any file format that contains T-Splines.
