bind_buffer()

void MayaFlux::Buffers::ShaderProcessor::bind_buffer	(	const std::string &	descriptor_name,
		const std::shared_ptr< VKBuffer > &	buffer
	)

Bind a VKBuffer to a named shader descriptor.

Parameters

descriptor_name	Logical name (e.g., "input", "output")
buffer	VKBuffer to bind

Registers the buffer for descriptor set binding. The descriptor_name must match a key in config.bindings.
