ClosestPointOnMesh / NearestPointOnMesh

Hi Guys

Think i'm getting a little confused.

Ive got a script that uses ClosestPointOnMesh, when I run it I get the error "cannot find procedure", I've searched the help files and found some info on it so I assume it should be there....

But I've had a google for it and found that it appears to have been replaced with nearestPointOnMesh at some point.

So the question is, has closest been replaced with nearest? If so, I just need to alter the script, if not am I missing something??

I'm using Maya 2008

Cheers

Steve

yes you are right.

Maya comes with nearestPointOnMesh. Check if this plugin in loaded in the plugin manager.
Just try to change it in your script, maybe it works...

On the other Hand.... I think the Bonustools delivers the closestPoinOnMesh.mll

Since maya 8, closestPointOnMesh is included. Before that it was available as a bonustool.

But it is a node that you create, rather than a proceedure that you run. Maybe if you show us the code we could comment further.

For example here is one way how you can create and use the CPOM

// create closestPointOnMesh node
// and connect it to the polymesh
//
string $cpom = eval("createNode closestPointOnMesh -n cpom1");
connectAttr -f mySurface.outMesh ($cpom + ".inMesh");

// create a transform node
// and connect it to the closestPointOnMesh node
//
string $loc = eval("createNode transform -n loc1");
connectAttr -f ($loc + ".translate") ($cpom + ".inPosition");

// get the uv coords from the closestPointOnMesh node
//
float $fu = `getAttr ($cpom + ".u")`;
float $fv = `getAttr ($cpom + ".v")`;


So $fu and $fv will be the uv's on the surface that are closest to the $loc transform.

(I have extracted this from another script and editted it so I appologise in advance if I typed something wrong. Hopefully you can still get the meaning)

Hi Guys


Thanks for clearing that up, I thought it might be something that I have to create (as I saw something similar on an old thread) but as I then saw some comments saying closest has been superceeded with nearest in version 8 or 8.5 I want too sure.

I changed the script form closest to nearest and it works fine now, but I will definatly bear it in mind.

The codes from the Autodesk Modeling with Maths training DVD, which I think if I remember reading the release notes is for version 7??

Cheers for the help its much appreciated.
