 In this project, we will explore the state of the art of current document formats including PDF, PostScript, SVG, HTML, and the limitations of each in terms of precision.
 We will consider designs for a document format allowing graphics primitives at an arbitrary level of zoom with no loss of detail. We will refer to such a document format as ``infinite precision''. A viewer and editor will be implemented as a proof of concept; we adopt a low level, ground up approach to designing this viewer so as to not become restricted by any single existing document format.

-It is necessary to clarify what we mean by ``infinite'' precision. We do not propose to be able to contain an infinite amount of information within a document. The goal is to be able to render a primitive at the same level of detail it is specified by a document format. For example, the precision of coordinates of primitives drawn in a graphical editor will always be limited by the resolution of the display on which they are drawn, but not by the viewer.

 There are many possible applications for documents in which precision is unlimited. Several areas of use include: visualisation of extremely large or infinite data sets; visualisation of high precision numerical computations; digital artwork; computer aided design; and maps.

+\subsection{Clarification of Terms}

+It may be necessary to clarify what we mean by the terms ``infinite precision'' and ``document formats''. Regarding the latter, we consider a document format to be any representation of visual information which is capable of being stored indefinitely. Regarding the former, we do not propose to be able to contain an infinite amount of information within such a document. The goal is to be able to render a primitive at the same level of detail it is specified by a document format, regardless of how precise this level is. For example, the precision of coordinates of primitives drawn in a graphical document editor will always be limited by the resolution of the display on which they are drawn, but not by the viewer.

 \section{Methods}
 
 Initial research and software development is being conducted in collaboration with David Gow\cite{proposalGow}. Once a simple testbed application has been developed, we will individually explore approaches for introducing arbitrary levels of precision; these approaches will be implemented as alternate versions of the same software. The focus will be on drawing simple primitives (lines, polygons, circles). However, if time permits we will explore adding more complicated primitives (font glyphs, bezier curves, embedded bitmaps).

+The process of rendering a document will be considered as a common area of research, whilst individual research will be conducted on means for allowing infinite precision.

 At this stage we have identified two possible areas for individual research:
