In LabVIEW 8.2,I can draw point,line,quads,etc,using 3D picture,but how to draw any text character such as 'abc' in 3D picture?

I have not found property or method of 3D picture to do this.

Thanks!

Is there no one to do relevant works? I think this should be the basic function of 3D picture based on OpenGL.

Error appears after building the VI ,Multi-Panel Front Panel using Splitter Bars.vi which is built-in LV8 examples.The VI runs correctly in LV8 while the error occurs after building exe.

When I press the button stop after maximizing the front panel it occurs. If not maximized the front panel the error will not and it runs correctly.

The error message is below:

Fatal Internal Error:"image.cpp",line 12727

LabVIEW version 8.0

You will lose any unsaved work.For assistance in resolving this problem,please relaunch LabVIEW,or contact National Instruments.

Thanks.

Have other somebody the same question? I really want to know the answer!

Hi LGK:

I agree with Ed Dickens-- Unless there's a reason not to (and I can't see one) you would be better off wiring directly to the terminal, rather than either the property node or the local variable.

I don't know offhand why the property node and the local variable are behaving so differently-- perhaps someone else can help with your original question. I do recall reading about differences in another thread in the forum, but I can't remember which one.

But if you can wire directly to the terminal, you will bypass the whole question, and probably have a routine that runs faster than either of the thumbnails you've shown.

Good Luck & Best Regards, Louis

Thanks.

The reason why I wire to "Property node" instead of directly to the terminal is that, the "sine wave" data perhaps may be wired to the different waveform graph sometimes in the different situation. So I put the references of waveform graph into an array and use them by index array. In my opinion, I feel it's easy to control the large application code by reference.

Are we talking about the node in the bottom loop in the Start Case?

The first question I have to ask is why are you considering using a Property node instead of just wiring directly to the terminal (not a Local Variable) like you have in the Local Variable version. There absolutly no reason to do this.

Not considering that, I've played with both version a bit and I don't see this pause happening with the property node. Could you give some more details on what is happening?

Ed

I'm sorry that "sine wave" should be wire to the "Local variable of the waveform graph" instead of directly to the terminal in the Local Variable version.

In the Property node version, it will not continue running until you selected an option of the right-click popup menu when the program display waveform. However, the Local Variable version will not.

The attached figures show the code differences between this two version:

I see you've been using OpenG Commander. In your attached llb, there are some missing strict-type controls. Can you re-save it with those?

I re_save it in the attached llb.

When I use "Right Popup Menu",there are some differences between "Local Variable" and "Property Node".The "Property Node" will cause program "Pause",but "Local Variable" will not.
