From 5368b98cd09f61a1e3344efed9ad90ac9989726e Mon Sep 17 00:00:00 2001 From: mm0zct Date: Sat, 29 Jun 2013 19:26:59 +0100 Subject: Merged in fixes to hydra and rift code, along with a bug in the pitch inversion of FTNoIR itself. Also added an include directory the Rift needs which was absent before. --- facetracknoir/facetracknoir.cpp | 8 +++--- facetracknoir/facetracknoir.h | 3 +-- facetracknoir/rotation.h | 54 +++++++++++++++++++++-------------------- facetracknoir/tracker_types.cpp | 2 +- 4 files changed, 35 insertions(+), 32 deletions(-) (limited to 'facetracknoir') diff --git a/facetracknoir/facetracknoir.cpp b/facetracknoir/facetracknoir.cpp index fafef908..623b16b2 100644 --- a/facetracknoir/facetracknoir.cpp +++ b/facetracknoir/facetracknoir.cpp @@ -682,9 +682,8 @@ void FaceTrackNoIR::startTracker( ) { // This is necessary, because the events are only triggered 'on change' // tracker->setInvertAxis(Yaw, ui.chkInvertYaw->isChecked() );
