 106         \frametitle{Why interoperability?}
 107
 108         The idea is to avoid unnecessary allocations and memory mappings when we
 109         exchange texture and buffer data across APIs.\\
 110         \vspace{0.3cm}
 111         Interoperability extensions allow us to:\\
 112         \vspace{0.8cm}
 113
 114         {\fontsize{9}{9}\selectfont
 115                 \begin{itemize}\setlength\itemsep{0.8cm}
 116                                 \item {\color[rgb]{0, 0, 0.6} Allocate the resources (textures,
 117                                         buffers) once.}
 118                                 \item {\color[rgb]{0, 0, 0.6} Reuse them several times from both
 119                                         APIs.}
 120                                 \item {\color[rgb]{0, 0, 0.6} Synchronize the APIs access to the
 121                                         resources.}
 122                 \end{itemize}
 123         }
 124 \end{frame}
 125
 126 \begin{frame}
 127         \frametitle{What's the alternative?}
 128
 129         Alternatively we would need to:\\
 130         \vspace{0.8cm}
 131
 132         {\fontsize{9}{9}\selectfont
 133                 \begin{itemize}\setlength\itemsep{0.8cm}
 134                                 \item {\color[rgb]{0, 0, 0.6} Allocate resources of the same
 135                                         size in both APIs.}
 136                                 \item {\color[rgb]{0, 0, 0.6} Map the Vulkan memory and copy the Vulkan object data to a an
 137                                         OpenGL object data (and \textit{do all the necessary
 138                                         conversions!}).}
 139                                 \item {\color[rgb]{0, 0, 0.6} Copy the data back after the process (and \textit{do all the
 140                                         necessary conversions!}).}
 141                                 \item {\color[rgb]{0, 0, 0.6} Synchronize the access externally
 142                                         (more complex).}
