3D Real-time Visualization

[ap8888]

Hello everyone.

I'm working on a program that will produce dynamic data (in the form of vectors or coordinates) that I would like to be used on a plot.

My readings produce continuous data that is used to plot a flexible tubular shape in various positions. The details are, I think, not necessary to be said here. As a simple example, imagine that I have an array of data listing X, Y, Z data. I would like to have this data plotted as a tubular shape, along with a specified diameter. I've come across "3D Picture Control", but before venturing off to learn this package, I thought I would ask whether this is really possible in LV, and, if not, how I should go about doing this.

In one of the documents talking about 3D Picture Control, they said that their software is good for simulating an aircraft's wing from strain gauge readings -- this is actually very similar to what I want to do. But I remain uncertain as to whether this is exactly what I need.

Please offer any help that you can.

The 3D picture control is if you want to draw your own 3D images. While you could use it for what you're doing, it sounds like you really want to draw a 3D graph. In that case, try one of the 3D graphs. In the Graph controls palette there are 3 types of 3D graphs. Each one is really an ActiveX control, and when you select one a VI gets placed on the block diagram where you can wire in your data. There are also examples for 3D graphs. (Help -> Find Examples)

Agree, 3d graph.

I did this using the 3-d graph to analyze pipes as they come of the end of the line.

Real-time is going be dependent on how efficient your code is and its CPU agraphic capabilities. If possible keep your data sets small.

You know, Ben, you always have the most awesome-looking graphs.

Ben,

Please share your code those graphics are amazing! -SS

OK but all I have is the demo that prodcued those images.

AND

If you ever acuse me of writing such horible code, .... well lets not go there.

PS Ben_Pipe12 is the demo and please observe the zip file size if you have a slow network.

Quick notes to undestand what that code does.

The data stream was acquired from a DAQ channel monitoring a micrometer.

The micrometer was moved along the length of pipe while it was being spun.

Most of the code in that example just re-aranged the data so I could visualize the pipe un-rolled and laid out flat or to image it a cylinder.

Ben,

I was interested in seeing your software flow.  I just started playing around with the CWplot3D control.  Looks like there is alot done in the properties settings of the control. 

Very cool and Thank You for sharing.  -SS

Ben,

The zip folder is missing some subVIs. Can you please post them too.

Thanks!

I'll guess not. Since SS opened it OK I can only guess that what is missing are actually on your machine.
