update_buffer()

void MayaFlux::Core::VKDescriptorManager::update_buffer	(	vk::Device	device,
		vk::DescriptorSet	set,
		uint32_t	binding,
		vk::Buffer	buffer,
		vk::DeviceSize	offset = 0,
		vk::DeviceSize	range = VK_WHOLE_SIZE
	)

Update descriptor set with buffer binding.

Parameters

device	Logical device
set	Descriptor set to update
binding	Binding index
buffer	Buffer to bind
offset	Offset in buffer (bytes)
range	Size to bind (VK_WHOLE_SIZE for entire buffer)

Binds a buffer to the specified binding point in the descriptor set. Must match the type declared in the layout (storage/uniform buffer).

Example: manager.update_buffer(device, set, 0, vk_buffer, 0, VK_WHOLE_SIZE); // Now shader can access: layout(binding=0) buffer Data { ... };
