Hull()

MayaFlux::Nexus::Hull::Hull ( std::shared_ptr< Buffers::VKBuffer >  buf, CrossingFn  on_enter = {}, CrossingFn  on_exit = {}, std::optional< uint32_t >  collection = std::nullopt  )

explicit

Build from a buffer.

Blocks for a ComputeMeshBuffer.

Parameters

buf	Buffer to wrap. Must not be null.
on_enter	Fired with the entity id when it enters. May be empty.
on_exit	Fired with the entity id when it leaves. May be empty.
collection	One collection of a NetworkGeometryBuffer to wrap, for a buffer that holds several bodies. Unset wraps all of it.
