upload_from_view()

template<typename T >

void MayaFlux::Buffers::upload_from_view	(	const Kakshya::DataAccess &	accessor,
		const std::shared_ptr< VKBuffer > &	target,
		const std::shared_ptr< VKBuffer > &	staging = nullptr
	)

Upload data from DataAccess view to GPU buffer (precision-preserving)

Template Parameters

T	View type (double, glm::dvec2, glm::dvec3, glm::vec3, float, etc.)

Parameters

accessor	DataAccess instance providing the view
target	Target GPU buffer
staging	Optional staging buffer (auto-created if needed)

Zero-copy when types match, automatic conversion cache when they don't. For AUDIO modalities, defaults to DOUBLE precision to preserve accuracy.
