create_2d() [2/2]

std::shared_ptr< Core::VKImage > MayaFlux::Portal::Graphics::TextureLoom::create_2d	(	uint32_t	width,
		uint32_t	height,
		ImageFormat	format = ImageFormat::RGBA8,
		const void *	data = nullptr,
		uint32_t	mip_levels = 1
	)

Create a 2D texture.

Parameters

width	Width in pixels
height	Height in pixels
format	Image format
data	Optional initial pixel data (nullptr = empty)
mip_levels	Number of mipmap levels (1 = no mipmaps)

Returns

Initialized VKImage ready for use

Creates device-local texture optimized for shader sampling. If data provided, uploads immediately and transitions to shader read layout.
