STL geometry object

 Hello, 

I am LabVIEW developer and i am new to the STL geometry coding.

I have load the STL image in the LabVIEW.  i am giving  the constant value to the rotate  X  and Y axis vi. still STL geometry image is flickering (Unsteadily) Ideally it should be at constant position. is any one knows the reason behind this ? or am I missing something. 

 

Thanks in advance

Do you want to continually rotate the device at a rate of 1kHz?

 

Or do you want to set a constant rotation value?

 

Your code is performing a rotate function every 1ms. Obviously, unless you have a very fast PC and extremely fast monitor, you're not going to see all of these. What you are seeing is a snapshot of your object's position whenever a screen refresh is happening. If anything, I'm surprised it's so repeatable.

 

Try using "Set rotation" instead of "Rotate" and slow down the loop by a factor of 20 or so. i.e. wait on ms with 20ms set. This is still a 50Hz update rate.
