create_render_target()

std::shared_ptr< Core::VKImage > MayaFlux::Portal::Graphics::TextureLoom::create_render_target	(	uint32_t	width,
		uint32_t	height,
		ImageFormat	format = ImageFormat::RGBA8
	)

Create a render target (color attachment)

Parameters

width	Width in pixels
height	Height in pixels
format	Image format (default RGBA8)

Returns

Initialized VKImage configured for rendering

Creates image suitable for use as framebuffer color attachment. Can also be sampled in shaders after rendering.
