First point always zero for Swing Trail

Swing trail first point always starts from zero. I had this strange problem in my project so i tried to reproduce this in the Rendering\17 - Swing Trail Effect.

Steps :
Change the weapon_matrix.setPosUp : Provide non zero vector say (5,1,5) as a position.
Run the program

You will see in first few frames the trails starts from 0,0,0 and then slowly gets stabilised at the mentioned matrix position. ?

Is there any solution to stop this ?

This is because all edges of Swing Trail are initialized with zeros:

Code:

T.edges.setNumZero(edges);

You can extend create method to provide your initial values and set up them for example using following snippet:

Code:

REPA(T.edges)

{

     T.edges[i].vtx[0].pos=pos;

     T.edges[i].vtx[1].pos=pos;

}

Does this snippet work in general or just in this particular case.
