How to access the transformation matrix between the raw world coordinate system and the calibrated coordinate system #617

Open skriabineSop opened 7 years ago

Hi I would like to set manually the position of a fake controller, using the api. However it seems that the coordinates I entered are by default expressed in the raw world coordinate system that seems to be centered on one of the lighthouse. Is there a way to access the transformation matrix between this raw coordinate system and the one set during the calibration of the vive system (headset on the floor) ?

Thanks

I think GetRawZeroPoseToStandingAbsoluteTrackingPose in IVRSystem does what you are looking for. Otherwise you could infer it by getting both raw and calibrated coordinates for the headest.

GetRawZeroPoseToStandingAbsoluteTrackingPose appears to always return empty.

What hardware are you on, @SteffanDonal ?

@JoeLudwig HTC Vive that's had room setup completed!

actually, there is a json config file on the steam folder/config named something like "chaperonne.vrchap" which contain the coordinate of the standing setup in the raw coordinate system and the yaw. So you can simply get everything from there
