+\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).}
