## Abstract
Computer-Generated Holography (CGH) is a set of algorithmic methods for identifying holograms that reconstruct Three-Dimensional
scenes in holographic displays. CGH algorithms decompose 3D scenes into multiplanes at different depth levels and rely on simulations
Computer-Generated Holography (CGH) is a set of algorithmic methods for identifying holograms that reconstruct Three-Dimensional (3D) scenes
in holographic displays. CGH algorithms decompose 3D scenes into multiplanes at different depth levels and rely on simulations
of light that propagated from a source plane to a targeted plane. Thus, for $n$ planes, CGH typically optimizes holograms using $n$ plane-to-plane
light transport simulations, leading to major time and computational demands. Our work replaces multiple planes with a focal surface and introduces
a learned light transport model that could propagate a light field from a source plane to the focal surface in a single inference. Our model leverages

## Results
When simulating a full-color, all-in-focus 3D image across a focal surface, conventional
Angular Spectrum Method (ASM) requires eighteen forward
passes to simulate the 3D image with six depth planes.
Angular Spectrum Method (ASM) requires eighteen forward passes to simulate the 3D image with six depth planes given there are three color primaries.
In contrast, our model simulates the three colorprimary images simultaneously
onto a focal surface with a single forward pass.
In the mean time, our model preserves more high-frequency content than U-Net, providing
