Inheritance diagram for Karma::GraphicsContext:

Public Member Functions
virtual void	Init ()=0
	For initializing Renderer and instantiating relevant objects.
virtual void	SwapBuffers ()=0
	This function swaps the front and back buffers of the specified window. If the swap interval is greater than zero, the GPU driver waits the specified number of screen updates before swapping the buffers.
virtual bool	OnWindowResize (WindowResizeEvent &event)=0
	Calls glViewport function which specifies the affine transformation of x and y from normalized device coordinates to window coordinates.
virtual	~GraphicsContext ()
	A destructor.

Detailed Description

An abstract class for creating a context for Renderer and provide graphics API.

Constructor & Destructor Documentation

~GraphicsContext()

virtual Karma::GraphicsContext::~GraphicsContext ( )

inlinevirtual

A destructor.

Since

Karma 1.0.0

Member Function Documentation

Init()

virtual void Karma::GraphicsContext::Init ( )

pure virtual

For initializing Renderer and instantiating relevant objects.

Since

Karma 1.0.0

Implemented in Karma::OpenGLContext, and Karma::VulkanContext.

OnWindowResize()

virtual bool Karma::GraphicsContext::OnWindowResize ( WindowResizeEvent & event )

pure virtual

Calls glViewport function which specifies the affine transformation of x and y from normalized device coordinates to window coordinates.

Todo

Seems OpenGL specific. Either think about usage in Vulkan or re design

Since

Karma 1.0.0

Implemented in Karma::OpenGLContext, and Karma::VulkanContext.

SwapBuffers()

virtual void Karma::GraphicsContext::SwapBuffers ( )

pure virtual

This function swaps the front and back buffers of the specified window. If the swap interval is greater than zero, the GPU driver waits the specified number of screen updates before swapping the buffers.

Todo

This seems to be an OpenGL specific call. Need to design api accordingly

Since

Karma 1.0.0

Implemented in Karma::OpenGLContext, and Karma::VulkanContext.
