Extrude?
Hi,

I have a quad in XZ plane and i want to extrude it in Y direction by 20 unit? How should i accomplish this?

The quad vertices and indices are set into meshbase object.

Thanks

base.vtx.pos("index of vertex you want to move").set(x,y,z)

I think you did not understand my questions. I want to extrude the quad. The function you provided will simply move the vertex to that position.

RE: Extrude?
MeshBase has various functions for adding vertexes/faces:
Code:
MeshBase& addVtx (C Vec        &pos                  ); // add empty vertex at 'pos' position
   MeshBase& addEdge(C VecI2      &ind                  ); // add edge     by giving vertex indexes
   MeshBase& addTri (C VecI       &ind                  ); // add triangle by giving vertex indexes
   MeshBase& addQuad(C VecI4      &ind                  ); // add quad     by giving vertex indexes
when you add a new element, it will always be at the last position (last index).

Yeah, I figured I had to do it different way. There is no inbuilt method in Esenthel for extruding. its natural btw even unity does not have a method to extrude.
