At ETH we developed a framework for 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.
