A cross-language, multi-platform API for rendering 2D and 3D vector graphics via hardware acceleration.

OpenGL (Open Graphics Library) remains the industry standard for high-performance graphics, providing a direct interface to the GPU for applications ranging from CAD software like AutoCAD to AAA game engines. Managed by the Khronos Group, it abstracts complex GPU hardware into a predictable state machine, allowing developers to execute GLSL shaders and manage vertex buffers across Windows, Linux, and Android. While newer APIs like Vulkan offer lower-level control, OpenGL’s massive ecosystem and simplified pipeline make it the go-to choice for rapid development in medical imaging, flight simulators, and scientific visualization.

## Recent Public Talks and Demos

### [Your Webcam Knows the Geometry - Real-Time Relighting & Single-Shot Novel Views](https://lausanne.aitinkerers.org/talks/rsvp_cMMuinG2WV4)

Two single-view inverse-rendering systems that reconstruct scene geometry from one camera and re-render it under conditions never captured — one changes the light, the other changes the viewpoint, both fast enough to ship. The Relighting part decomposes a live webcam frame into geometry + material (normals/albedo/shading) and re-renders it under any lighting in real time (~24 FPS), showcasing a variety of lighting conditions (multiple colored lights, orbiting and rainbow-rotating lights) The Novel View Synthesis builds a 3D representation of the scene using Gaussian Splatting and renders it from a different angle. It currently runs at 5 FPS but we are hoping to get closer to real time soon.

### [Custom GPU-powered LLMs and Graph Neural Networks](https://boston.aitinkerers.org/talks/rsvp_LZl89lqLF3c)

A demo on running a variety of open LLMs with the power of GPUs. May dabble in using GPUs for graph neural networks trained on knowledge graphs.
