* doc: Add missing template clauses in qmatrix4x4.cppMartin Smith2018-01-121-2/+2
| | | | | | | | Added a few missing template clauses to member functions and friends. Change-Id: Ie5ca557ddcc1dfd90ef5e80fc4e8213dfb32a03c Reviewed-by: Topi Reiniö <topi.reinio@qt.io>
* Use qRadiansToDegrees() and qDegreesToRadians() more widelyEdward Welbourne2017-07-051-3/+3
| | | | | | | | | | | | | | | | Especially in examples, where we should show off our convenience functions, prefer calling these functions over doing arithmetic with M_PI (or approximations thereto) and 180 (give or take simple factors). This incidentally documents what's going on, just by the name of the function used (and reveals at least one place where variables were misnamed; the return from atan is in radians, *not* degrees).

* Use C++ <cmath> instead of <math.h>Allan Sandfeld Jensen2015-02-161-8/+8
| | | | | | | | | | | | | | Including math.h can pollute the default namespace, and break some compilers if cmath versions of the method are declared as using. Switching to C++ math functions also greatly simplifies handling of float qreal as C++ automatically chooses the right method. [ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any sources depending on that indirect inclusion may fail to build.

* Make gui/math3d classes use float rather than qrealSean Harmer2012-09-071-161/+196
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This corrects the mismatch between using floats for internal storage and qreal in the API of QVector*D which leads to lots of implicit casts between double and float. This change also stops users from being surprised by the loss of precision when using these classes on desktop platforms and removes the need for the private constructors taking a dummy int as the final argument. The QMatrix4x4 and QQuaternion classes have been changed to use float for their internal storage since these are meant to be used in conjunction with the QVector*D classes. This is to prevent unexpected loss of precision and to improve performance. The on-disk format has also been changed from double to float thereby reducing the storage required when streaming vectors and matrices. This is potentially a large saving when working with complex 3D meshes etc. This also has a significant performance improvement when passing matrices to QOpenGLShaderProgram (and QGLShaderProgram) as we no longer have to iterate and convert the data to floats. This is an operation that could easily be needed many times per frame. This change also opens the door for further optimisations of these classes to be implemented by using SIMD intrinsics.
