A function takes values and returns a result.  The function "Length3D(0,0,0,10,10,10)" typed into a edit box will return the 3D length between 0,0,0 and 10,10,10.  (The answer is 17.321.  Try it in any edit box.)

This article shows how to use embedded math functions in VTube float point edit boxes.

Contents


The Floating Point Edit Box Embedded Calculator

As of version 3, VTube-STEP and VTube-LASER includes an embedded calculator in the floating point edit boxes anywhere in the main user interface.

See this example of how it works.


This is the tube before the change.

Editcalc 002.png

Choose the LL value in the LRA grid.

Editcalc 001.png

Subtract 5.2 like this:

Editcalc 003.png

The VTube calculator returns the result in the edit box like this:

Editcalc 004.png

Now reverse-calc the data and this is the new tube.
