3D picture control speed/latency

[Pete_Culmer]

Hi,

I'm doing some work using the 3D picture control in Labview 8.2.1. I'm interested in getting as fast a response as possible so that the time between asking for a scene update and it being displayed on the screen is minimal. I'm using a hardware accelerated window. What kind of response times should I expect? Best case is the time taken for one screen update but I'm guessing there must be more overhead than that?

Also, is it worth upgrading to Labview 8.6 for improvements in the 3D picture control?

Any help much appreciated,

Cheers,

Pete

Hi Pete,

Its very hard to define an exact update rate for a 3d picture control as it will be defendant on the model being used, but a key factor is using it in a hardware accelerated render window rather than the embedded window.

Upgrading to a newer version of LabVIEW is likely to give you some performance enhancements depending on the code behind the scenes especially if you are using a dual or quad core machine as LabVIEW 8.5 onwards takes advantage of a lot of multicore developments which may help you in processing the model.

I would suggest downloading the eval edition of LabVIEW 8.6 and giving it a try as this will give you the full tools to test for 30 days.
