FAccelerationStructureHandle

Wrapper that holds both physics thread data and GT data.

API > API/Runtime > API/Runtime/Chaos

Wrapper that holds both physics thread data and GT data. It's possible that the physics handle is null if we're doing operations entirely on external threads

Functions

Public

Name Remarks Include Path Unreal Specifiers

void DebugDraw ( const bool bExternal,
const bool bHit
) const

   Chaos/ParticleHandle.h  

FGeometryParticle * GetExternalGeometryParticle_ExternalThread()

 Should only be used by GT and scene query threads where an appropriate lock has been acquired. Chaos/ParticleHandle.h  

FGeometryParticleHandle * GetGeometryParticleHandle_PhysicsThread()

 Should only be used by PT. Chaos/ParticleHandle.h  

bool PrePreQueryFilter ( const void* QueryData
) const

Static

Name Remarks Include Path Unreal Specifiers

static void ComputeParticleQueryFilterDataFromShapes ( const TParticle& Particle,
FCollisionFilterData& OutQueryFilterData
)

 Compute the aggregated query collision filter from all associated shapes. Chaos/ParticleHandle.h  

static void ComputeParticleSimFilterDataFromShapes ( const TParticle& Particle,
FCollisionFilterData& OutSimFilterData
)

 Compute the aggregated sim collision filter from all associated shapes NOTE: may not initialize OutQueryFilterData, so it must be cleared before calling if necessary (e.g., when changing blocking channels) Chaos/ParticleHandle.h
