How to list all vertices in a mesh?

[kmagill]

This seems an absurdly simple question, and I feel embarrassed for asking it, but:

How do I list all vertices in a polygon mesh?

i.e. do something that returns polySurface1.vtx[0], polySurface1.vtx[1],

[kmagill]

found a way,

int $count;
int $nVerts = pollyEvaluate -vertex $myPoly; //gets number of vertices in myPoly
for ($count = 0; $count < $nVerts; $count++)
{
//do somthing with $myPoly.vtx[$count]
}

there we go, saved abit of face and hopefully will help someone else out sometime.

Also, if you have all the verticies selected in the mesh:

string $allVerts[] = ls -sl -fl;

if you have just the mesh selected:

PolySelectConvert 3;
string $allVerts[] = ls -sl -fl;

I always use something similar to kmagill's technique. Use polyEvaluate to get the total vert count and then I build a string representing all verts in compressed format...

int $vertcount = polyEvaluate -vertex $object;
string $allVerts = ($object + ".vtx[0:" + ($vertcount - 1) + "]" );

In most cases using a command that works on all verts fed to it in compressed format is faster than looping through the verts yourself since the API handles it instead of a MEL loop.
