Comparing Microfacet Multiple Scattering with Real-Life Measurements
Microfacet multiple scattering approximations change content authoring – both for good (energy conservation) and for not so good (saturation changes with roughness). I was curious how current microfacet multiple scattering techniques compare against a measured real-life reference. After all, real-life surfaces … Continue reading

Biome Painter: Populating Massive Worlds
There is a steady rise of popularity of open-world games and their domination of the bestseller list. Every new game raises the bar for the world size and complexity. Just looking at recent open world game trailers reveals their aim … Continue reading

Cloth Shading
Over the holiday break I had some time to play with interesting ideas presented during the last SIGGRAPH. One thing which caught my attention was new analytical cloth BRDF from Sony Pictures Imageworks [EK17], which they use in movie production. … Continue reading

Digital Dragons 2017
A few days ago I had a chance to attend and speak at Digital Dragons 2017 about rendering in Shadow Warrior 2. It was a total blast – very pro organized, had a honor to meet some incredible people and listen to … Continue reading

HDR Display – First Steps
Recently NVIDIA send us a nice HDR TV and we got a chance to checkout this new HDR display stuff in practice. It was a rather a fast implementation, as our game is shipping in less than 2 months from … Continue reading

Automatic Exposure
In games automatic exposure or eye adaptation is an algorithm for simulating eye reaction to temporal changes in lighting conditions and for selecting optimal exposure for a given scene and lighting conditions. The main challenge here is that optimal settings … Continue reading

ACES Filmic Tone Mapping Curve
Careful mapping of HDR values to LDR is an important part of a modern game rendering pipeline. One of the goals of our new renderer was to replace Reinhard‘s tone mapping curve with some kind of a filmic tone mapping … Continue reading

Analytical DFG Term for IBL
Image-based lighting is an important part of a physically based rendering. Unfortunately straightforward IBL implementation for more complicated lighting models than Phong requires a huge lookup table and isn’t practical for real time. Current state of the art approach is … Continue reading

Lightmapping in Anomaly 2 mobile
In 2013 Anomaly 2 mobile version (iOS/Android/Blackberry) by a small indie studio 11 Bit Studios was released. It was an interesting project as we needed to run heavy content from PC version on much weaker mobile platforms. I’d like to … Continue reading

Octahedron normal vector encoding
Many rendering techniques benefit from encoding normal (unit) vectors. For example in deferred shading G-buffer space is a limited resource. Additionally it’s nice to be able to encode world space normals with uniform precision. Some encoding techniques work only for … Continue reading
