upload_data() [2/2]

void MayaFlux::Portal::Graphics::TextureLoom::upload_data	(	const std::shared_ptr< Core::VKImage > &	image,
		const void *	data,
		size_t	size,
		const std::shared_ptr< Buffers::VKBuffer > &	staging
	)

Upload pixel data reusing a caller-supplied persistent staging buffer.

Identical to upload_data() but skips the per-call VkBuffer allocation, eliminating the Vulkan object churn that causes VK_ERROR_DEVICE_LOST under sustained per-frame texture updates (e.g. video playback).

Parameters

image	Target VKImage (must already be initialised).
data	Pixel data pointer (at least size bytes).
size	Byte count — must match the image footprint.
staging	Host-visible staging VKBuffer from create_streaming_staging().
