Unlike sWONDER + (see~\ref{subsec:swonder}), the \gls{ssr} is not able to interpolate + movement. When a new location for a source is requested, the movement + is carried out instantly, whereas sWONDER is able to move a source (on + a straight line) from one position to the next in a given time frame.\\ + A series of movements can be requested in any desired time frame, which + means, that spatial aliasing is very likely to occur, during sets of + requests with a short time span between them.\\ + To work around this, the \gls{ssr} should implement a comparable + feature to the one sWONDER facilitates and apply rate limiting on the + source positioning request, depending on a dynamically settable + threshold value in milliseconds.\\ + Applications, such as WFSCollider (see~\ref{subsec:wfscollider}) or 3Dj + (see~\ref{subsec:3dj_supercollider_quark}) rely on their \gls{gui} or + rather \gls{sclang} to implement dynamic movements (e.g.\ circular or + randomized) \citep[pp. 56-62]{manual:wfscollider}. While the creative + process of source paths generation is clearly best placed in a visually + interactive process, its communication with the rendering engine has to + be high-performance and if scalable to large setups, ideally with low + network throughput.\\ + Therefore it has to be evaluated, if implementing a set of understood + geometrical shapes, instead of sending a high frequency of source + positioning messages could be a more feasible solution in the case of + the \gls{ssr}. In~\ref{subsubsec:dynamic_scene} a wider approach to + this problem is discussed. \subsubsection{Dynamic scene} \label{subsubsec:dynamic_scene} + \subsubsection{Network enabled head tracking} + \label{subsubsec:network_enabled_headtracking} + \cleardoublepage \pagestyle{empty} \cleardoublepage |
