Does track pose work in blocks for ultimate goal? #121

Open tjhawkey opened 3 years ago

tjhawkey commented 3 years ago

I'm trying to extract pose information using blocks for a teaching example, but any call of track pose generates this error message Error: Fatal error occurred while executing the block labeled "call VuforiaUltimateGoal.trackpose"

I took the canned vuforia webacm example and added one block. Works fine when this block is disabled. Image attached.

C270 Vuforia Test (1)

The trackPose block is supposed to:

Returns the VuforiaTrackingResults of the pose of the trackable with the given name. ' + 'The pose is the location of the trackable in the phone\'s coordinate system.

It is not useful when using a webcam. It shouldn't crash though!

Thanks. I don't yet see why track pose wouldn't work with a webcam since you can return global coordinate results from vuforia with a webcam. Doesn't it just go by what camera is defined for vuforia? It would be very nice to get track pose to work in blocks.
