Past, Present and Future Challenges of Global Illumination in GamesColin Barré-Brisebois
Global illumination (GI) has been an ongoing quest in games. The perpetual tug-of-war between visual quality and performance often forces developers to take the latest and greatest from academia and tailor it to push the boundaries of what has been realized in a game product. Many elements need to align for success, including image quality, performance, scalability, interactivity, ease of use, as well as game-specific and production challenges.
First we will paint a picture of the current state of global illumination in games, addressing how the state of the union compares to the latest and greatest research. We will then explore various GI challenges that game teams face from the art, engineering, pipelines and production perspective. The games industry lacks an ideal solution, so the goal here is to raise awareness by being transparent about the real problems in the field. Finally, we will talk about the future. This will be a call to arms, with the objective of uniting game developers and researchers on the same quest to evolve global illumination in games from being mostly static, or sometimes perceptually real-time, to fully real-time.

Course presentation at SIGGRAPH 2014 by Charles de Rousiers and Sébastian Lagarde at Electronic Arts about transitioning the Frostbite game engine to physically-based rendering.
Make sure to check out the 118 page course notes on: http://www.frostbite.com/2014/11/moving-frostbite-to-pbr/
During the last few months, we have revisited the concept of image quality in Frostbite. The core of our approach was to be as close as possible to a cinematic look. We used the concept of reference to evaluate the accuracy of produced images. Physically based rendering (PBR) was the natural way to achieve this. This talk covers all the different steps needed to switch a production engine to PBR, including the small details often bypass in the literature.
The state of the art of real-time PBR techniques allowed us to achieve good overall results but not without production issues. We present some techniques for improving convolution time for image based reflection, proper ambient occlusion handling, and coherent lighting units which are mandatory for level editing.
Moreover, we have managed to reduce the quality gap, highlighted by our systematic reference comparison, in particular related to rough material handling, glossy screen space reflection, and area lighting.
The technical part of PBR is crucial for achieving good results, but represents only the top of the iceberg. Frostbite has become the de facto high-end game engine within Electronic Arts and is now used by a large amount of game teams. Moving all these game teams from “old fashion” lighting to PBR has required a lot of education, which have been done in parallel of the technical development. We have provided editing and validation tools to help the transition of art production. In addition, we have built a flexible material parametrisation framework to adapt to the various authoring tools and game teams’ requirements.

Unite Berlin 2018 - Book of the Dead Optimizing Performance for High End Cons...Unity Technologies
In this session, the Unity Demo team provides their best tips and tricks for optimizing detailed, complex environment scenes for modern console performance.
Speakers:
Rob Thompson (Unity Technologies)
This talk provides additional details around the hybrid real-time rendering pipeline we developed at SEED for Project PICA PICA.
At Digital Dragons 2018, we presented how leveraging Microsoft's DirectX Raytracing enables intuitive implementations of advanced lighting effects, including soft shadows, reflections, refractions, and global illumination. We also dove into the unique challenges posed by each of those domains, discussed the tradeoffs, and evaluated where raytracing fits in the spectrum of solutions.
For this year's keynote at High Performance Graphics 2018, Colin Barré-Brisebois from SEED discussed the state of the art in real-time game ray tracing. He explored some of the connections between offline and real-time game ray tracing, and presented some of the open problems. Colin exposed a few potential solutions to those problems, and also proposed a call-to-arms on topics where the ray tracing research community and the games industry should unite in order to solve such open problems.
Taking Killzone Shadow Fall Image Quality Into The Next GenerationGuerrilla
This talk focuses on the technical side of Killzone Shadow Fall, the platform exclusive launch title for PlayStation 4.
We present the details of several new techniques that were developed in the quest for next generation image quality, and the talk uses key locations from the game as examples. We discuss interesting aspects of the new content pipeline, next-gen lighting engine, usage of indirect lighting and various shadow rendering optimizations. We also describe the details of volumetric lighting, the real-time reflections system, and the new anti-aliasing solution, and include some details about the image-quality driven streaming system. A common, very important, theme of the talk is the temporal coherency and how it was utilized to reduce aliasing, and improve the rendering quality and image stability above the baseline 1080p resolution seen in other games.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

2. About REYES Reyes or REYES (Renders Everything You Ever Saw) A flexible renderer, developed by Lucasfilm CG div. (“Pixar” from 1986) First used in 1984 in Start Trek II ..still used today in Pixar’s Photorealistic RenderMan 2 * Images, from top, are copyright of Paramount Pictures and Pixar (subsidiary of The Walt Disney Company)
3. RenderMan compliant ? Defines a renderer with some basic capabilities such as: A RenderMan graphics state machine Hidden surface elimination Pixel filtering and anti-aliasing User programmable shaders Texture mapping Etc… 3
4. REYES features Native support for high level surfaces Dynamic LOD Compact representation Subdivide per-frame based on size on screen Displace geometry from textures High quality filtering Easier to deal with translucency, motion-blur, etc. Can be used together with ray-tracing 4
10. Split (5) Split recursively until every sub-patch is “small enough”… Small enough.. this is ready to be diced 10
11. What’s “Small Enough” ? When most sub-patches fit in a single bucket When dicing(see later) produces a suitable number of samples (sweet spot for performance) Sub-patch inside a single bucket Optimal Sub-patch touches two or more buckets Not Optimal A bucket 11
12. Dice Small enough sub-patches are diced Generate a dense grid of samples (1 pixel-per-sample or more..) 1 pixel Small enough n_samples <= max_samples max_samples is set for performance reasons and to avoid distortion 12
13. Displace Apply a displacement shader to the position of the samples myDisplace() { mag = texture( “dispmap” ); P += normalize(N) * mag; N = calculatenormal(P); } 13
14. Shade Apply surface and light shaders to get the color myShader() { txcol = texture( “pigment” ); Ci = diffuse(N,txcol); Oi = 1; } 14
15. Sample – the micropolys Form virtualmicropolygons at the grid samples 1 pixel Virtual micropolygons 15
16. Sample – sample points Multiple sub-samples at every pixel …choose a sampling method: regular, multi-jittered (as shown), etc. 16
17. Sample – gather samples Samples get the color of the micropolygons they touch …each sample can have many values if the mpolys are translucent ! 17
18. Sample – convolution Mix the samples together… …choose a filter: box, triangular, Gaussian, Sinc, etc.. 18
19. Sample – final pixel color The resulting “average” color is assigned to the pixel …repeat for every pixel 8) 19
21. RibTools’ key features RenderMan compliant(…almost (^^;)) Parse RIB scene files C-like shaders compiler and VM Parametric surfaces, etc. Sub-pixel displacement mapping Open Sourced (BSD License) Multi-threaded Network-distributed “Future proof” SIMD Scalability ! 21
22.
23. Buckets are assigned to threads on the CPU or to remote servers via TCP/IP
24. Geometry, shaders and textures are also transferred via TCP/IPWorks today ! …it’s only a start. Needs optimizations, esp. network. .............. 22
25.
26. RRASM is assembled and executed by the ShaderVirtual Machine (VM) when renderingShader VM 23

30. Prospects for RibTools What role will REYES play for real-time ? The architecture bodes well with multi-core, vector processors or even GPGPU Displacement and curved surfaces are best with smaller-than-a-pixel polygons anyway Develop, learn and innovate Don’t let the others decide for you..Fully programmable graphics hardware is coming Off-line rendering ? Much more complex, but no real-time constraints DX11 tessellation ..almost micro-polygons! * RenderAnts: REYES on GPGPU Siggraph 2008, 2009 ** 27 * From Unigine’s Direct3D 11 tech demo ** Image from RenderAnts renderer
31. Cons and problems Requires highly programmable hardware (best if with a flexible texture unit) The “RenderMan interface” is a fairly deep standard to follow Shader compilers, optimizers.. complex stuff Comes with other issues: Cracks when tessellating, non-planar micropolys, front plane clipping, etc. ..but someone’s got to try it 8) 28
