Member Function Documentation

GetUpdateGeometryType()

UpdateGeometryType Urho3D::BillboardSet::GetUpdateGeometryType ( )

overridevirtual

Return whether a geometry update is necessary, and if it can happen in a worker thread.

Reimplemented from Urho3D::Drawable.

OnWorldBoundingBoxUpdate()

void Urho3D::BillboardSet::OnWorldBoundingBoxUpdate ( )

overrideprotectedvirtual

Recalculate the world-space bounding box.

Implements Urho3D::Drawable.

ProcessRayQuery()

void Urho3D::BillboardSet::ProcessRayQuery ( const RayOctreeQuery &  query, Vector< RayQueryResult > &  results  )

overridevirtual

Process octree raycast. May be called from a worker thread.

Reimplemented from Urho3D::Drawable.

UpdateBatches()

void Urho3D::BillboardSet::UpdateBatches ( const FrameInfo &  frame )

overridevirtual

Calculate distance and prepare batches for rendering. May be called from worker thread(s), possibly re-entrantly.

Reimplemented from Urho3D::Drawable.

UpdateGeometry()

void Urho3D::BillboardSet::UpdateGeometry ( const FrameInfo &  frame )

overridevirtual

Prepare geometry for rendering. Called from a worker thread if possible (no GPU update).

Reimplemented from Urho3D::Drawable.
