update_image()

void MayaFlux::Core::VKDescriptorManager::update_image	(	vk::Device	device,
		vk::DescriptorSet	set,
		uint32_t	binding,
		vk::ImageView	image_view,
		vk::Sampler	sampler = nullptr,
		vk::ImageLayout	layout = vk::ImageLayout::eGeneral
	)

Update descriptor set with image binding.

Parameters

device	Logical device
set	Descriptor set to update
binding	Binding index
image_view	Image view to bind
sampler	Sampler (for combined image samplers, null for storage images)
layout	Image layout (typically eGeneral or eShaderReadOnlyOptimal)

Binds an image to the specified binding point in the descriptor set. For storage images: sampler = null, layout = eGeneral For sampled images: provide sampler, layout = eShaderReadOnlyOptimal
