* QtGui/math3d: Fix QQuaternion::getEulerAngles for GimbalLock casesYuya Nishihara2022-01-161-16/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is heavily inspired by the patch written by Inho Lee <inho.lee@qt.io>, 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).

| | | | | | | | | | | | | | | | | | | | | I made a clazy automated check that replaced the use of QVariant::Type by the equivalent in QMetaType. This has been deprecated since Qt 5.0, but many uses were not yet removed. In addition, there was some manual changes to fix the compilation errors. Adapted the Private API of QDateTimeParser and QMimeDataPrivate and adjust QDateTimeEdit and QSpinBox. QVariant(QVariant::Invalid) in qstylesheet made no sense. But note that in QVariant::save, we actually wanted to use the non-user type. In the SQL module, many changes were actually reverted because the API still expects QVarient::Type.

* 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.
