abstract     : We present a framework for the holographic representation and
display of graphics objects. As opposed to traditional graphics
representations, our approach reconstructs the light wave reflected
or emitted by the original object directly from the underlying
digital hologram. Our novel holographic graphics pipeline consists
of several stages including the digital recording of a full-parallax
hologram, the reconstruction and propagation of its wavefront, and
rendering of the final image onto conventional, framebuffer-based
displays. The required view-dependent depth image is computed from
the phase information inherently represented in the complex-valued
wavefront. Our model also comprises a correct physical modeling of
the camera taking into account optical elements, such as lens and
aperture. It thus allows for a variety of effects including depth of
field, diffraction, interference and features built-in
anti-aliasing. A central feature of our framework is its seamless
integration into conventional rendering and display technology which
enables us to elegantly combine traditional 3D object or scene
representations with holograms. The presented work includes the
theoretical foundations and allows for high quality rendering of
objects consisting of large numbers of elementary waves while
keeping the hologram at a reasonable size.
