Tangent CV Script

[mromey]

Hi,

I recently received the Non-Organic Surface Modeling DVD from Alias Wavefront. In the dvd a Peter Bakic discribes different techniques for modeling. In it he menions a tangent CV script of which I thought would be located within the dvd's tutorial or source material. Anyhow long story short, no script. I'm trying to make a tangent CV script that takes three selcetd cv's and moves the third cv to the center position of the first 2 cv's. So far this is what I understand.

x3 = (x2 + x1)/2
y3 = (y2 + y1)/2
z3 = (z2 + z1)/2

I need some assistance trnasforming this equation into a usable Mel script.

Using the following sniplet of code I'm able to find the value of each point, but I don't quite understand how to find the value of the first cv selected and apply it to a variable in order to process the equation.

xform -q -ws -t nurbsPlane1.cv[0][3] ;
xform -q -ws -t nurbsPlane1.cv[1][3] ;
xform -q -ws -t nurbsPlane1.cv[2][3] ;

I'm guessing I have to create some type of while loop to assign the value of a given axis to a variable to process the equation. Any direction anyone could offer would be great.

Thanks in advance.

actually, the script is available on highend:

It's in the pdf file on the DVD (the course notes he refers to). Peter's script is actually easier to use than the one available on Highend. Just select the points in order and hit the Mel button.

I copied the text from the pdf into a text file to make a script. But when I ran it I got all kinds of error messages. If you can get it working, please post it as I'm not a Mel wiz.

I have to admit I was pretty disappointed with the lack of content in this DVD. There was a few small tips but not much. The Patch Modeling DVD from AW was light years better.

Cheers

How did you copy the text from your pdf files? Have you ever tried text extraction from pdf files before? I am looking for some help. Any suggestion will be appreciated. Thanks in advance.
