\section[Introduction]{The concept behind OpenGL and Vulkan interoperability}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{frame}
	\frametitle{Why interoperability?}

	The idea is to avoid unnecessary allocations and memory mappings when we
	exchange texture and buffer data across APIs.\\
	\vspace{0.3cm}
	Interoperability extensions allow us to:\\
	\vspace{0.8cm}

	{\fontsize{9}{9}\selectfont
		\begin{itemize}\setlength\itemsep{0.8cm}
				\item {\color[rgb]{0, 0, 0.6} Allocate the resources (textures,
					buffers) once.}
				\item {\color[rgb]{0, 0, 0.6} Reuse them several times from both
					APIs.}
				\item {\color[rgb]{0, 0, 0.6} Synchronize the APIs access to the
					resources.}
		\end{itemize}
	}
\end{frame}

\begin{frame}
	\frametitle{What's the alternative?}

	Alternatively we would need to:\\
	\vspace{0.8cm}

	{\fontsize{9}{9}\selectfont
		\begin{itemize}\setlength\itemsep{0.8cm}
				\item {\color[rgb]{0, 0, 0.6} Allocate resources of the same
					size in both APIs.}
				\item {\color[rgb]{0, 0, 0.6} Map the Vulkan memory and copy the Vulkan object data to a an
					OpenGL object data (and \textit{do all the necessary
					conversions!}).}
				\item {\color[rgb]{0, 0, 0.6} Copy the data back after the process (and \textit{do all the
					necessary conversions!}).}
				\item {\color[rgb]{0, 0, 0.6} Synchronize the access externally
					(more complex).}
		\end{itemize}
	}
