Enum PxSceneQueryUpdateMode 

#[repr(i32)]
pub enum PxSceneQueryUpdateMode {
    BuildEnabledCommitEnabled = 0,
    BuildEnabledCommitDisabled = 1,
    BuildDisabledCommitDisabled = 2,
}

Scene query update mode

This enum controls what work is done when the scene query system is updated. The updates traditionally happen when PxScene::fetchResults is called. This function then calls PxSceneQuerySystem::finalizeUpdates, where the update mode is used.

fetchResults/finalizeUpdates will sync changed bounds during simulation and update the scene query bounds in pruners, this work is mandatory.

eBUILD_ENABLED_COMMIT_ENABLED does allow to execute the new AABB tree build step during fetchResults/finalizeUpdates, additionally the pruner commit is called where any changes are applied. During commit PhysX refits the dynamic scene query tree and if a new tree was built and the build finished the tree is swapped with current AABB tree.

eBUILD_ENABLED_COMMIT_DISABLED does allow to execute the new AABB tree build step during fetchResults/finalizeUpdates. Pruner commit is not called, this means that refit will then occur during the first scene query following fetchResults/finalizeUpdates, or may be forced by the method PxScene::flushQueryUpdates() / PxSceneQuerySystemBase::flushUpdates().

eBUILD_DISABLED_COMMIT_DISABLED no further scene query work is executed. The scene queries update needs to be called manually, see PxScene::sceneQueriesUpdate (see that function’s doc for the equivalent PxSceneQuerySystem sequence). It is recommended to call PxScene::sceneQueriesUpdate right after fetchResults/finalizeUpdates as the pruning structures are not updated.

Variants

BuildEnabledCommitEnabled = 0

Both scene query build and commit are executed.

BuildEnabledCommitDisabled = 1

Scene query build only is executed.

BuildDisabledCommitDisabled = 2

No work is done, no update of scene queries

Trait Implementations

impl Eq for PxSceneQueryUpdateMode

impl PartialEq for PxSceneQueryUpdateMode

fn eq(&self, other: &PxSceneQueryUpdateMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
