Mantle() [1/3]

MayaFlux::Nexus::Mantle::Mantle	(	const Kinesis::AABB3D &	bounds,
		std::shared_ptr< Buffers::VKBuffer >	buf,
		Portal::Graphics::FitMode	fit = Portal::Graphics::FitMode::STRETCH,

		CrossingFn	on_exit = {}
	)

Build from a box and a buffer.

Blocks for a ComputeMeshBuffer.

Parameters

bounds	World-space box.
buf	Buffer to place. Must not be null.
fit	How the buffer's geometry fills the box.
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.
