Explore wave and ray optics for light-based tomographic 3D printing in this JuliaCon 2024 conference talk. Dive into four key Julia packages: RadonKA.jl for fast Radon transforms, DiffImageRotation.jl for differentiable image rotation, WaveOpticsPropagation.jl for efficient wave optical propagations, and SwissVAMyKnife.jl for solving optimization problems in Tomographic Volumetric Additive Manufacturing (TVAM). Learn about the implementation of exponential Radon transforms, CUDA-supported image rotation, scalable angular spectrum methods, and Fraunhofer diffraction propagation. Gain insights into the novel TVAM technique for rapid centimeter-scale 3D printing. Access the presented notebook on GitHub and discover how these packages contribute to advancing light-based 3D printing technology.
