write() [3/16]

void MayaFlux::Portal::Forma::Bridge::write	(	const ElementRef &	ref,
		const std::shared_ptr< Buffers::VKBuffer > &	target_buffer,
		const std::string &	shader_path,
		uint32_t	offset,
		size_t	size = sizeof(float)
	)

Route element value to a push constant slot on a ShaderProcessor.

Parameters

ref	Owning Layer and element id.
target	VKBuffer whose push_constant staging receives the value.
offset	Byte offset in the push constant struct.
size	Byte width. Defaults to sizeof(float).
