Computer presentations are an integral part of our lives, yet the contemporary presentation tools have not changed for about three decades, still emulating old overhead slide projectors. Combined with the rapid evolution of computer graphics technologies, this results in contemporary tools being ill-suited for many modern needs where linear sequences of fixed-sized 2D slides consisting of text and images is not nearly sufficient. In this work, we propose a presentation system aimed at overcoming the limitations of the contemporary presentation software. To achieve this goal, we abandon the usual concept of a presentation as a 2D slide sequence, and instead treat them as continuous automatically created 3D scenes of non-linear structure with multi-modal content, all without requiring any professional skills from the end user.

Abstract-This paper describes Beholder Framework, which is a set of libraries designed to provide a single low-level API for modern real-time graphics that combines clarity of Direct3D 11 and portability of OpenGL. The first part of the paper describes the architecture of the framework and its reasoning from the point of view of developing a cross-platform graphics application. The second part describes how the framework overcomes some most notable pitfalls of supporting both Direct3D and OpenGL that are caused by differences in design and object models of the two APIs.
