create_element() [1/2]

template<typename T >

Mapped< T > MayaFlux::Portal::Forma::create_element	(	Layer &	layer,
		std::shared_ptr< Core::Window >	window,
		GeometryFn< T >	geom,
		T	initial,
		Graphics::PrimitiveTopology	topology = Graphics::PrimitiveTopology::TRIANGLE_STRIP,
		size_t	capacity = internal::k_capacity_bytes,
		std::function< float(T)>	project = {}
	)

Build a FormaBuffer, register it, construct a Mapped<T>, and add the element to layer.

BufferManager is taken from the stored initialize() state. Returns the fully constructed Mapped<T>. The caller holds it. element.id is stable and can be passed to Context callbacks and Bridge.

Template Parameters

T	MappedState value type: float, glm::vec2, etc.

Parameters

layer	Layer to register the element on.
window	Target window for rendering.
geom	Geometry function producing vertex bytes from T.
initial	Starting value written into MappedState.
topology	Primitive topology for the FormaBuffer.
capacity	Initial FormaBuffer capacity in bytes.
project	Optional T -> float projection for outbound readers.

Returns

Fully constructed Mapped<T> with element registered in layer.
