* QQuaternion: long live Axes / toAxes()Marc Mutz7 days1-12/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Compilers hate out parameters, so provide a replacement for getAxes(), toAxes(), that returns the result in a struct Axes { x, y, z } instead. Then make getAxes() an inline wrapper around a toAxes() call, porting from Q_ASSERT(x && y && z) to Q_PRE(x); Q_PRE(y); Q_PRE(z); as a drive-by. The separation gives a more detailed error when triggered, and produces a shorter assertion string. Add tests, naturally, and port getAxes() calls that don't test getAxes() to the new function. There appear to be no other in-tree users that could be ported. For symmetry reasons, also add a fromAxes(Axes) overload. Take the argument by value, to avoid the compiler having to deal with aliasing analysis. At worst, pass-by-value is like pass-by-cref, and whether or not the extra copy is added or, since C++17, elided, depends on the specific call. Suppress Clazy's schizophrenic warning, which complains that we don't take (QVector3D, QVector3D, QVector3D) by value, but also if we take struct {QVector x,y,z} by value. [ChangeLog][QtGui][QQuaternion] Added toAxes(), a getAxes() replacement.

* QQuaternion: make methods constexpr, noexcept; fix styleVolker Hilsheimer2023-12-091-41/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Use atan2() in Quaternion axis-and-angleEdward Welbourne2023-08-181-1/+1
| | | | | | | | | | | | | | | | | It's more numerically robust than acos() - we can't hit a range error if we get strange rounding effects - and we've got the value of the sin of the angle already (it's the length of the x, y, z part), so might as well use it. As length is necessarily positive, atan2() will give an upper-half-plane resolution, matching what acos() gave us. This incidentally means that you no longer need to normalize() your quaternion before you ask for axis and angle.

* QtGui/math3d: Fix QQuaternion::getEulerAngles for GimbalLock casesYuya Nishihara2022-01-161-16/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is heavily inspired by the patch written by Inho Lee <[email protected]>, which says "There is a precision problem in the previous algorithm when checking pitch value. (In the case that the rotation on the X-axis makes Gimbal lock.)" In order to work around the precision problem, this patch does: 1. switch to the algorithm described in the inline comment to make the story simple. 2. forcibly normalize the {x, y, z, w} components to eliminate fractional errors. 3. set threshold to avoid hidden division by cos(pitch) =~ 0. From my testing which compares dot product of the original quaternion and the one recreated from Euler angles, calculation within float range seems okay. (abs(normalize(q_orig) * normalize(q_roundtrip)) >= 0.99999) Many thanks to Inho Lee for the original patch and discussion about rounding errors.

* Rationalize QQuaternion's length-scaling codeEdward Welbourne2021-02-041-56/+40
| | | | | | | | | | | | | | | | | | | | | Use qHypot() to implement length(), avoid duplicating its code and use its result more carefully, saving the need for casting to and from double. Subtracting a double from 1.0f still got a double, so the qFuzzyIsNull() checks were using double's tolerance, where the use of 1.0f indicates the float tolerance would have been more apt. Also, use qFuzzyCompare(_, 1.0f) instead of qFuzzyIsNull(_ - 1.0f). In getEulerAngles(), scale co-ordinates by length before multiplying (to ensure O(1) quantities) rather than scaling the products by the squared length (possibly after {ov,und}erflowing).

* Make gui/math3d classes use float rather than qrealSean Harmer2012-09-071-44/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This needs to be applied in conjunction with https://codereview.qt-project.org/#change,33548 Task-number: QTBUG-21035 Task-number: QTBUG-20661 Change-Id: I9321b06040ffb93ae1cbd72fd2013267ac901b2e Reviewed-by: Lars Knoll <[email protected]>

| | | | | | | | | | QPair is small and is no problem to include from qdatastream.h. However, including QDataStream from qpair.h means including QIODevice and QObject too.
