Description: This hands-on lab introduces Slang, an open-source, open governance shading language hosted by Khronos that simplifies graphics development across platforms. Designed to tackle the growing complexity of shader code, Slang offers modern programming constructs while maintaining top performance on current GPUs. Participants will get practical experience with Slang’s standout features: a module system that streamlines code organization, generics and interfaces that eliminate preprocessor headaches, and cross-platform capabilities for write-once, run-anywhere development. We’ll cover integrating Slang with industry tools like Renderdoc and VSCode, and demonstrate converting existing GLSL and HLSL code to Slang. We’ll also briefly introduce advanced features like automatic differentiation and bindless capabilities. Whether you’re developing games, working in visualization, or researching new rendering techniques, you’ll gain practical skills to immediately improve your graphics workflow and prepare for next-generation rendering challenges.

Description: Gaussian splats are a rapidly emerging method for the fast and efficient creation of photorealistic 3D visualizations and are particularly suitable for real-time applications. Today, a growing number of software solutions support the capture, visualization, editing, and compression of Gaussian splats. However, as different companies and organizations adopt varying formats, the risk of ecosystem fragmentation and a lack of interoperability becomes a real possibility. However, timing is everything in standardization. Premature efforts risk stifling innovation, while waiting too long can lead to fragmented proprietary technologies. The sweet spot is when a technology’s utility is proven, and the absence of standards starts to hinder adoption and growth. By fostering collaboration among users, tool developers, and engine vendors, this workshop seeks to discuss the state of current technologies, formats, and use cases to guide the evolution of Gaussian splat interoperability and help remove pain points, drive adoption and prevent fragmentation.

Description: This Lab invites participants to explore how today’s Vulkan ecosystem tools and resources allow everyone to write real-time raytraced effects with far less boilerplate than in the past. Building on a trimmed version of the open-source Khronos Vulkan Tutorial and the vk-bootstrap and Vulkan-RAII[2] helper libraries, we will incrementally assemble a renderer that combines rasterization with ray tracing to implement accurate shadows. The session balances bite-sized coding intervals with short concept discussions, so that every participant leaves with a runnable project and a mental map of where to dig deeper afterward.
