Today, we are going to discuss the paper published by NVIDIA's Pascal Gautron, which introduces a technique called 'Hashed Raytraced Ambient Occlusion' (HRTAO). Unlike traditional screen-space methods, this technique utilizes multi-resolution spatial hashing that adapts the level of detail based on camera distance for scene lighting, effectively eliminating visual noise.

This time, we will discuss the presentation given by Mikkel Gjoel and Mikkel Svendsen from Playdead during the Game Developers Conference 2016. In it, they talk about the rendering strategies used to create the visual atmosphere of INSIDE—from the use of blue noise and temporal anti-aliasing for its minimalist aesthetic, to the efficient handling of volumetric fog, water reflections, and shadows while maintaining 60 FPS.

On this occasion, we will discuss the presentation given by Jalal El Mansouri, Technical Architect at Ubisoft Montreal, during the Game Developers Conference 2016. In it, he talks about how they implemented the material management system for Rainbow Six Siege by grouping draw calls into efficient batches and using unified buffers to optimize the processing of procedural destruction.Watch full presentation:

Today, we’ll be discussing a talk given by Timo Heinapurola from the game studio Supercell at the Game Developers Conference 2023. In it, he explains the process of replacing the rendering engine in their biggest hits, like Clash of Clans and Brawl Stars. He covers how they created a more efficient, modern cross-platform abstraction layer for APIs like Metal and Vulkan, and how they used automated testing to ensure quality for their existing user base.

On this occasion, we will discuss the presentation given by Wannes Vanderstappen, Senior Graphics Programmer at Larian Studios, during the Graphics Programming Conference 2025. He talks about the transition of their graphics engine from their previous game, Divinity: Original Sin 2, to their most recent title, Baldur's Gate 3, featuring a high-fidelity cinematic aesthetic.

On this occasion, we are going to analyze this paper presented at Pacific Graphics 2025, which introduces an iterative and efficient method for updating lightmaps. It avoids recalculating the entire lighting from scratch by processing only the residual changes generated when inserting or removing objects using a light transport operator.Read full paper:

Today, we will discuss the paper presented by Christoph Peters at SIGGRAPH ASIA 2025. In this work, he aims to improve volume rendering fidelity by adapting the jackknife estimation technique, which employs an elegant extension of complex number arithmetic to neutralize bias in light transport through media such as clouds or smoke.Read full paper:

Today, we’re going to discuss the presentation given at SIGGRAPH 2025 by Thiago Souza, Rendering Technical Director at id Software. He talked about the Global Illumination system developed for their new engine, idTech 8 (used in games like Doom and Indiana Jones). The system replaces slow, static baking with real-time ray tracing using Cascaded Radiance Volumes, allowing for immediate changes in the artistic workflow without having to wait up to 40 hours for bakes.

Today we're talking about a 2006 paper that leverages Spherical Harmonics to simplify object visibility and create real-time soft shadows in dynamic settings. By modeling objects as clusters of spheres, it easily handles deformable characters and maintains fluid GPU performance, utilizing spherical harmonic exponentiation for the visibility reconstruction.
