We do this by using either /etc/machine-id, or hashing the MACs of all
non-virtual networking devices.
We make this fingerpint unique to our platform by adding our own string
to the hash, and add some stretching for good measure. This way Vircadia's
fingerprint isn't going to match the system's ID or anything another
application generates.
When a Resource is requested from qrc://, the Resource::handleDownloadProgress
event is never called, and therefore _bytesTotal remains at zero. This confuses
ResourceCache later, which has a sanity check that doesn't pass when resources
are retrieved, yet no data accumulates.
Fixes#1065
Changed the default value of FloatPreference::_step from 0.1f to 1, because FloatPreference::_decimals defaults to 0. Also because before this branch, all spinners used a step of 1 rather than SpinnerPreference::_step.
Spinners such as Settings > General > Desktop Tablet Scale / VR Tablet Scale work again.
* Removed the deprecated MyAvatar.setToggleHips script function and the "Toggle Hips Following" option from the Developer menu. They had no effect on any code.
* In CharacterController::applyMotor, prevented unnecessary calls to btVector3::rotate() when the motor has no rotation. This change also improves readability through the use of clearly-named lambdas.
* In AvatarData::getFauxJointIndex, prevented unnecessary string comparisons when the named joint is a real joint rather than a faux one.
* In Avatar::getJointIndex, removed an unnecessary call to QHash<QString, int>::contains(), by supplying a default index for QHash<QString, int>::value().
* Removed unnecessary condition "forwardLeanAmount < 0" in MyAvatar::FollowHelper::shouldActivateHorizontal_userSitting.
* Corrected the return type of MyAvatar::getSitStandStateChange from float to bool.
* Added a missing 'f' suffix to a float literal in PreferencesDialog.cpp.
This helps with log flooding. Successive repeated log messages will be skipped and counted,
the count will be output when a different message is logged.
A new option of 'keep_repeats' has been added to VIRCADIA_LOG_OPTIONS to disable this.
Fix z-write being enabled for transparencies in GeometryCache::getSimplePipeline and Procedural::Procedural (fixes https://github.com/vircadia/vircadia/issues/224).
Z-write is controlled by the 'writeMask' parameter of gpu::State::setDepthTest.

The ones I've left are either
- values known at compile time, eg. const float MIN_LENGTH_FOR_NORMALIZE = 0.061f;
- consts that were already there in the previous code, eg. const float MAX_DISPLACEMENT = 0.5f * _radius;
(https://github.com/vircadia/vircadia/issues/117)
- In SpinBoxPreference.qml, SpinBox was missing "realStepSize: preference.step".
- Had to change FloatPreference::step from float to double, because there is some truncation happening somewhere. For example, a step of 0.01f was acting like 0.00 because (0.01f < 0.01).
- Changed FloatPreference::decimals (number of decimal places) from float to uint, because it seemed to make more sense.
- Changed the 'User real-world height' spinbox to use a resolution of 1cm (for display and step) rather than 1mm.
- Remaining bug: the up & down buttons of the spinbox fail to change the value, at some values, though the mouse wheel always works. Repro:
Settings > Controls > User real-world height
Hover the mouse over the box and and scroll the mouse wheel down until the value is at 1.15.
Click the up button a few times and observe that the number can't be increased.
Scroll the mouse wheel forward and observe that the number increases correctly.
- Todo: Change all calls to FloatPreference::setStep to pass doubles, if this change to its parameter type is kept.
Error was: "static_assert expression is not an integral constant expression", "read of non-constexpr variable 'MINIMUM_TIME_REMAINING' is not allowed in a constant expression".
Error started in last commit (2179c153de).
- Divided the option "Avatar leaning behavior" into two options that work more usefully: "Allow my avatar to stand" and "Allow my avatar to lean" (PreferencesDialog.cpp). Made the necessary fixes so that the avatar can be set to stand only when the user is standing (more details below).
- The logic controlling the direction of MyAvatar's action motor is now centralised in calculateScaledDirection (was previously split between there and updateMotors). calculateScaledDirection now returns a velocity in world space.
- CharacterController::FollowHelper now uses separate follow timers for rotation, horizontal and vertical (previously followed all three based on the longest of their follow times). Where appropriate, FollowHelper can now snap immediately to the desired rotation/horizontal/vertical independently (see FOLLOW_TIME_IMMEDIATE_SNAP).
- FollowHelper::FollowType has therefore moved to CharacterController::FollowType.
- MyAvatar::FollowHelper::postPhysicsUpdate: If MyAvatar is not allowed to stand when the user is sitting, this now avoids recentring the body based on the head height.
- Removed Q_PROPERTY(MyAvatar::SitStandModelType, as the sitting/standing/leaning model uses different enums now (see setAllowAvatarStandingPreference, setAllowAvatarLeaningPreference).
- Removed Q_PROPERTY(bool isSitStandStateLocked which is no longer used, because we now always track the user's real-world sit/stand state, regardless of what we're doing with it.
- MyAvatar::FollowHelper::shouldActivateHorizontal: If MyAvatar is not allowed to lean, this now returns true to recentre the footing if the head is outside the base of support.
- MyAvatar::FollowHelper::shouldActivateHorizontalCG: If MyAvatar is not allowed to lean, this now always returns true to recentre the footing. Rearranged to avoid computing values that weren't used depending on the conditions. Resolved some duplicated code.
- MyAvatar::setUserRecenterModel previously set HMDLeanRecenterEnabled based on the chosen mode, but it got reset when getting out of a sit. Now HMDLeanRecenterEnabled is only controlled by the scripts.
- Added Rig::getUnscaledHipsHeight (like getUnscaledEyeHeight). Refactored a little to avoid duplicated code. Added DEFAULT_AVATAR_HIPS_HEIGHT which is the value that Rig::getUnscaledHipsHeight returns when using the default avatar.
- Fix for recentring not behaving as requested by the user after getting up from click-to-sit (always behaving like 'Auto') : MyAvatar::endSit now passes false to centerBody for 'forceFollowYPos'.
- Fix for incorrect vertical position of the avatar and viewpoint after changing lean recentre mode while not standing in the real world: MyAvatar::setAllowAvatarStandingPreference now calls centerBody with false for 'forceFollowYPos'.
- computeHipsInSensorFrame: The code now matches the comments in that it only skips the dampening of the hips rotation if the centre-of-gravity model is being used.
This will work fine on non-Linux systems, because the query should
simply fail on systems that don't support it.
This should improve functionality on nouveau
Fixes a lot of:
warning: ‘constexpr QFlags<T>::QFlags(QFlags<T>::Zero) [with Enum = QFileDialog::Option; QFlags<T>::Zero = int QFlags<QFileDialog::Option>::Private::*]’ is deprecated: Use default constructor instead [-Wdeprecated-declarations]
Set VIRCADIA_LOG_OPTIONS to a string containing these keywords:
color
milliseconds
process_id
thread_id
The separator doesn't matter. Example:
$ export VIRCADIA_LOG_OPTIONS="color milliseconds"
GLVND appears to break the entire UI on ATI video cards.
It was set to GLVND due to an understanding that this was a no-op setting, but it turns
out the documentation in OpenGL_GL_PREFERENCE is confusing, and it looks like LEGACY
is the setting that was being used after all.
An additional point of interest is that debian/rules contained OpenGL_GL_PREFERENCE=GLVND,
and this was done back in the High Fidelity days. It's uncertain whether this was correct
or not, though.
