Celebrating 20 Years of Innovation in Real-Time Rendering

Two Decades of Game-Changing Progress

As the field of computer graphics evolves, the significance of SIGGRAPH's Advances in Real-Time Rendering in Games has become increasingly apparent. This course has established itself as a leading forum for unveiling state-of-the-art rendering techniques that fuel the real-time interactive experiences of today and tomorrow. Now entering its third decade, it continues to shape the industry with groundbreaking insights and innovations.

A Groundbreaking Initiative

What began as a grassroots effort to connect rendering engineers, game developers, and technical artists has transformed into a global forum that merges cutting-edge research with practical industry execution. Over the years, the program has consistently highlighted the latest advancements that are shaping video games, virtual productions, architectural visualizations, and large-scale interactive experiences.

Voices of the Industry

Natalya Tatarchuk, CTO of Activision and a long-time program organizer, reflects, "Advances in Real-Time Rendering in Games endures because it's more than a technical session; it's a living time capsule of the state of real-time rendering. Each year, we gather visionaries and innovators who seek to push boundaries, showing that curiosity and exploration are at the heart of our progress."

A Legacy of Innovation

Initially aimed at bridging the knowledge gap for developers engaged in real-time rendering, the Advances in Real-Time Rendering in Games has influenced top studios and game engines worldwide. This program has introduced transformative techniques that are now ubiquitous in the industry, including screen-space ambient occlusion, physically based lighting, GPU-driven pipelines, and neural global illumination—often years before they became mainstream.

Key Innovations Over the Years

Notable moments from the past include Crytek's introduction of screen-space ambient occlusion, which laid the groundwork for real-time graphics. Additionally, the program highlighted pioneering work in temporal anti-aliasing and compute-based rendering pipelines, showcased by visionaries such as Alex Evans. More recently, innovations in global illumination, integrating machine learning and neural compression techniques presented by Activision and studios like Naughty Dog, emphasized the course's focus on practical, real-world solutions.

This Year’s Exciting Lineup

In 2025, the course will feature a two-part session on August 12, which will include a special retrospective by Tatarchuk. Attendees can expect pioneering presentations from industry leaders such as:

• Activision discussing a scalable solution for order-independent transparency in "Call of Duty."
• Ubisoft detailing their technical advancements in merging ray tracing with global illumination for "Assassin's Creed Shadows."
• MachineGames revealing how they achieved film-quality rendering at over 60 frames per second in "Indiana Jones and the Great Circle."
• id Software showcasing real-time global illumination techniques for improved workflow and artistic flexibility in "DOOM: The Dark Age."
• HypeHype presenting a novel local lighting algorithm that enhances user-generated content across various devices.
• NVIDIA unveiling a hybrid subsurface scattering technique for stunning skin and translucent material rendering.
• Epic Games introducing MegaLights, a stochastic direct lighting system that boosts performance and realism in Unreal Engine 5.

Looking Forward: Opportunities Ahead

As the Advances in Real-Time Rendering in Games course embarks on its third decade, the future looks promising but complex. "We are at a pivotal inflection point, with traditional GPU pipelines still holding unexploited potential," Tatarchuk notes. At the same time, challenges like platform fragmentation call for rendering solutions that can deliver consistent fidelity across diverse hardware generations.

The momentum surrounding generative AI also presents unique opportunities for disruption in real-time pipelines, pushing boundaries further. Techniques initially developed for gaming are now influencing the realms of film and simulation, reflecting the cross-pollination that has been a hallmark of this program from the start.

Ultimately, the message remains clear: every frame produced must respond to the player, ensuring that their interactions carry weight and are not simply scripted. This principle remains the cornerstone of what defines 'real-time' rendering.
