nearestPointOnMesh 的一点坑

发表于
Maya里使用nearestPointOnMesh的一点小坑。 An issue I found about nearestPointOnMesh in Maya.

nearestPointOnMesh 是Maya里一个很有用的功能，他能求得一个物体上与你给定的位置离最近的点。但最近我在使用时遇到点小坑。

nearestPointOnMesh is a very useful node in Maya，however Ifound a little issue when I use it。

它有两种使用方式，一个是节点，一个是命令。要使用它得先去插件管理器里启用它。

Two ways to use it, Node or Command. Must be enabled in the plugins manager before it can be use.

###节点方式 Node

得先用脚本创建出节点;

First create the node by Mel;

1
2
3
//Mel

createNode nearestPointOnMesh;

打开大纲，显示里取消勾选DAG objects Only 就能找到。

Uncheck “DAG objects Only” in Outline-Display, then you can find the node there.

指定好 inputMesh 和 inputPoint 就能求出下面结果。

Connect something to inputMesh and inputPoint， Evaluations result can be found below.

###命令模式 Command

使用方法maya给的帮助是这样:

Quick Help is given like this:

那么坑来了。按照我的惯例，要求值，我会习惯写成

Here’s the issue, in my style, qure would be type in this way:

1
2
3
//Mel

nearestPointOnMesh -q -p -ip 1.0 1.0 1.0 pTorus1;

但是是会报错。

However,it gives me a error.

1
2
3
4
//Mel

//Error: line1: Invalid object or value: 1//
//Error: A mesh or its transform node must be specified as a command argument, or use your current selection.//

后发现写成这样就行 Then It works with this way:

1
2
3
//Mel

nearestPointOnMesh -ip 1.0 1.0 1.0 -p -q pTorus;

That’s all, thanks.
