Change Log

Mar 13th 2022 - 2.8.0

• Updates for Qt6 compatibility (thanks Björn).

Nov 17th 2019 - 2.7.2

• Fix includes in camera.h (thanks Gianluca and Laurent).

Nov 17th 2017 - 2.7.1

• Fix deprecated message in constructor. Fixes #39 (thanks Carsten).

Jun 14th 2017 - 2.7.0

• QGLViewer extends QOpenGLWidget instead of the deprecated QGLWidget (huge thanks to Gianluca).
• Although there are minor differences between the two classes, the switch should be mostly invisible.

  Using update() instead of updateGL() is one of them

  The renderText methods were backported to maintain backward compatibility.

  Some overloaded constructors (using a QGLFormat or a sharedWidget) are deprecated since they have no equivalent.

Jul 16th 2016 - 2.6.4

• Add a -qt4 or -qt5 suffix to library file name on Linux. Fixes #18 (thanks Laurent).
• Edit the .pro of the examples to support the debug version of the library on Windows. Fixes #23 (thanks naubry).
• contribs examples no longer build by default. Relied on deprecated GL calls (Fixes #31)
• Add QMAKE_MAC_SDK to fix compilation on Mac with recent XCode versions
• Fix compilation errors on ARMv7, when `qreal` is defined to `float` (Pull request from lrineau)

Jul 16th 2015 - 2.6.3

• Add dependency to native OpenGL drivers on Windows platform. No longer implicit since ANGLE is an alternative in Qt 5.5 (thanks Andrea and Laurent).
• The library is now always built in the QGLViewer directory. The examples' pro files are simplified and more robust.
• Add some libGlu dependency in examples that rely on it (thanks Brice).

Jan 23nd 2015 - 2.6.2

• Fix qreal issue in Quaternion::FromRotationMatrix() (thanks Che, again).

Jan 22nd 2015 - 2.6.1

• Bug fix in Camera::pointUnderPixel() introduced by the switch to qreal (thanks Che).
• terrain contrib example is deprecated.

Nov 17th 2014 - 2.6.0

• The entire API now consistently uses the qreal (i.e double) type for floating point numbers.
  This should not break code compatibility since types will mostly get automatically converted.
  Update your code if you use one of the getX(qreal & x) methods, which take a reference as a parameter, and which type needs to be changed to qreal.

Nov 6th 2014 - 2.5.4

• Remove libGLU dependency on Mac since it conflicts with Yosemite (thanks Hae-Jeong, Federico).

• Mouse binding getter functions names have been harmonized.
• setMouseBinding methods accept only one button, instead of an improbable combination of buttons.
