What we’re about
We are the Silicon Valley local chapter for the Association for Computing Machinery's (ACM) Special Interest Group on Computer Graphics and Interactive Techniques (SIGGRAPH).
Our mission is to promote the generation and dissemination of information on computer graphics and interactive techniques.
Our purpose is to foster a membership community whose core values help them to catalyze the innovation and application of computer graphics and interactive techniques.
We meet roughly every month, usually on the third Thursday. Our chapter has been officially meeting for over 15 years, but it goes back over 35 years.
We hold an annual presentation of the SIGGRAPH Electronic Theater, a video presentation of cutting edge computer animation from the recent SIGGRAPH conference.
Topics we have covered: VR/MR/AR, Visual Effects (VFX), Game Development, Animation, Mobile, Ray Tracing, CNN, Model Creation, Web, 3D Printing, New Standards,….
Past speakers have come from: Industrial Light & Magic (ILM), Unity, Stanford, NVIDIA, Pixar, UC Berkeley,….

# Design of Holographic Display Systems based on Artificial Intelligence
Suyeon Choi, Postdoctoral Scholar, Stanford University
Wednesday, September 18, 2024, 7:00 PM PDTAbstract
Emerging spatial computing systems are widely believed to be next-generation computing platforms, offering transformative experiences across various domains such as teleconferencing, education, entertainment, industry, and basic vision research, among others. To deliver perceptually realistic and visually comfortable experiences, optical interfaces, such as imagers or displays, must be compact, adaptable, seamlessly integrated, and capable of efficiently encoding and robustly reconstructing visual information. However, most of these parameters are not achieved by existing optical devices, mainly limited by the high-dimensional, low-latency nature of the visual signals and the sensitive, complex nature of human sensory systems that must be fully satisfied. In this talk, I will describe how computational optical systems can provide solutions to these interfaces for augmented and virtual reality (AR/VR) applications. First, I will introduce an artificial intelligence (AI)-based algorithmic framework that comprises several parts, including a novel camera-in-the-loop optimization strategy that allows us to either optimize a hologram directly or train a parameterized model of the optical wave propagation and a neural network architecture that represents the first computer-generated holography (CGH) algorithm capable of generating full-color high-quality holographic images at 1080p resolution in real-time. Efficiently and accurately modeling arbitrary optical systems, these frameworks overcome long-standing challenges in holography, such as low image quality and prohibitive computational cost. Next, I will present computational design methodologies powered by my framework, which enable full-color, high-quality 3D images within glasses form factors for AR/VR displays. I will also discuss how this advancement paves the way for studying 3D human perception, leveraging a holographic perceptual testbed. Finally, I will discuss future directions that I’m excited to explore.Bio
Suyeon Choi is a final-year Ph.D. student at Stanford University, advised by Professor Gordon Wetzstein. His research centers on developing computational optical systems at the intersection of graphics, computational optics, artificial intelligence, and applied vision science. He received a Meta Research PhD Fellowship, a SPIE Optics and Photonics Education Scholarship, a Kwanjeong Scholarship, a Korean Government Scholarship, and a Frontiers of Science Award. He was also a finalist for the NVIDIA Graduate Fellowship, a recipient of the Presidential Science Scholarship for undergraduate studies. Previously, he received his Master's and Bachelor’s degrees in Electrical Engineering from Stanford University and Seoul National University, respectively.
His research was demonstrated at SIGGRAPH 2023 Emerging Technologies.Published works
