Starting with the Qt 6.5.0 release, the Qt Quick 3D Physics module is no longer in Tech Preview. As a result of the API feedback and review process, some source-incompatible changes were made.
The majority of the changes are renaming types and properties for consistency with other APIs and to make the names more descriptive. The most noticeable rename is changing DynamicsWorld to
PhysicsWorld, which will affect all applications.
The most important behavioral change is the handling of kinematic bodies. Changing the position/orientation of a kinematic body is no longer done
by using the Node properties (position, rotation, etc.), but instead by using the new properties: kinematicPosition, kinematicEulerRotation, kinematicRotation, and kinematicPivot. The reason for this change
was to make sure that the visual movement of kinematic bodies is synchronized with the rest of the simulation, instead of happening one simulation step too early.
The DynamicRigidBody.density property no longer treats negative values (and zero) as a special case. Instead, there are two new massMode enumeration values replacing Density:
DefaultDensity |
The density of the body is defined by PhysicsWorld.defaultDensity. This is the default. |
CustomDensity |
The density of the body is defined by the density property. |
The enableTriggerReports property has been renamed to sendTriggerReports. In addition, physics objects can now be
notified when they enter a trigger body by setting receiveTriggerReports.
The following is a complete list of all the API changes:
CollisionNode to PhysicsNode
speed to movement
meshSource to source
heightMap to source
meshSource to source
DynamicsWorld)
forceDebugView to forceDebugDraw
minTimestep/maxTimestep to minimumTimestep/maximumTimestep
axisLockLinearX/Y/Z properties into a single property linearAxisLock that takes a bitfield
axisLockAngularX/Y/Z properties into a single property angularAxisLock that takes a bitfield
Density enum value to DefaultDensity/CustomDensity and removed special-casing of negative values.
linearVelocity property with the method setLinearVelocity.
angularVelocity property with the method setAngularVelocity.
