World space position of a face

[stevesayer]

Can anyone help me with a script to return the world space position of a poly face?
eg

world space of poly.f[0];

Have tried with polyMoveFacet in query mode, but can't map results to a float array.

Thanks in advance

ok wild guess but trty using getAttr with the -ws flag (or something im too tierd to test)

This would be a complete hack.... and there's probably a command out there to do it but... you could find all the verts that make up the selected face with the polyInfo command, then use pointPosition to get each of the verts worldspace positions, and then just compute the average...

The easiest way to get coordinates of anything in world space is to use the xform command:

xform -q -ws -t pSphere1.f[0];

Note that in this instance this will give you a list of four triplets, each of which are the x, y, and z positions for a corner of the face. If you want a centroid you'll have to average each of x, y, and z yourself.

float $fWorld[] =xform -q -ws -bb;

	$tx=($fWorld[0]+$fWorld[3])/2;
	$ty=($fWorld[1]+$fWorld[4])/2;
	$tz=($fWorld[2]+$fWorld[5])/2;

print ($tx+" "+$ty+" "+$tz+" "+" n ");

Or by using the boundingbox of the face, will get a better result if the face is nonplanar
