Synthetic Holograms of Splines

In this paper we present an approach for the holo- graphic imaging of objects composed of splines. It is based on an imaging method for lines and extended to fit the requirements for the visualization of 3D curves. The input object consisting of splines is decomposed into line segments. These segments are subsequently transferred into the holographic equivalent—a set of textured rectangles appropriately placed in 3D space. Proper rectangle orientation and texture distortion al- low a narrow approximation of holographic patterns generated by cylindrical and conical waves. Our approach allows faster hologram generation compared to traditional methods. We employ com- puter graphics rendering, exploiting hardware support for the rendering of textured geometry.
