* QQuaternion: make methods constexpr, noexcept; fix styleVolker Hilsheimer2023-12-091-95/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The class stores all data inline, and most member functions are inline already with trivial arithmetic operations on those data members. So we can make the class almost completely constexpr. This includes member functions that construct or use QVector3D/4D, as those types are also fully constexpr. Almost all inline (and now constexpr) member functions can then also be made noexcept, with the exception of the division operators that don't check the divisor for 0. qFuzzyCompare(float, float) is not noexcept, but it has no preconditions and never throws, so we can make the QQuaternion overload noexcept. Remove const from values returned by arithmetic operators, and fix whitespace style in prototypes (also the few that are not already touched by the other changes). Prepare unexporting the class wholesale in Qt 7; we only have to export out-of-line functions, but can't make that change in Qt 6, as the implicitly defined special member functions are exported (at least on MSVC).

* Replace discouraged Q_MOVABLE_TYPE by Q_RELOCATABLE_TYPEAndreas Buhr2020-11-301-1/+1
| | | | | | | | | | | | | | Q_MOVABLE_TYPE was conceived before C++ had move semantics. Now, with move semantics, its name is misleading. Q_RELOCATABLE_TYPE was introduced as a synonym to Q_MOVABLE_TYPE. Usage of Q_MOVABLE_TYPE is discouraged now. This patch replaces all usages of Q_MOVABLE_TYPE by Q_RELOCATABLE_TYPE in QtBase. As the two are synonymous, this patch should have no impact on users.

| | | | | | | | | | | | | | | | | | | ...by dropping the use of qIsNull(), which, in Qt 4, distinguished between -0.0f and +0.0f. But mathematically, whether x, y, z are ±0 doesn't change the fact that the result is the identity element (x, y, z should contain the identity element for addition and w the one for multiplication), or the null element (additive identity). So using qIsNull() was wrong even in Qt 4. In Qt 5, qIsNull() returns true for both ±0, so we can just as well compare to 0.0f instead, which allows to mark these functions constexpr (qIsNull() can't be). Do so.

* Make gui/math3d classes use float rather than qrealSean Harmer2012-09-071-48/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
