Evolution of Programmable Models for Graphics Engines (High
Hello and welcome! Today I want to talk about the evolution of programmable models for graphics engine programming for algorithm developing My name is Natalya Tatarchuk (some folks know me as Natasha) and I am director of global graphics at Unity I recently joined Unity… 4 …right after having helped ship the original Destiny @ Bungie where I was the graphics lead and engineering architect … 5 and lead the graphics team for Destiny 2, shipping this year. Before that, I led the graphics research and demo team @ AMD, helping drive and define graphics API such as DirectX 11 and define GPU hardware features together with the architecture team. Oh, and I developed a bunch of graphics algorithms and demos when I was there too. At Unity, I am helping to define a vision for the future of Graphics and help drive the graphics technology forward. I am lucky because I get to do it with an amazing team of really talented folks working on graphics at Unity! In today’s talk I want to touch on the programming models we use for real-time graphics, and how we could possibly improve things. As all in the room will easily agree, what we currently have as programming models for graphics engineering are rather complex beasts. We have numerous dimensions in that domain: Model graphics programming lives on top of a very fragmented and complex platform and API ecosystem For example, this is snapshot of all the more than 25 platforms that Unity supports today, including PC, consoles, VR, mobile platforms – all with varied hardware, divergent graphics API and feature sets. -

Rendering 13, Deferred Shading, a Unity Tutorial
Catlike Coding Unity C# Tutorials Rendering 13 Deferred Shading Explore deferred shading. Fill Geometry Bufers. Support both HDR and LDR. Work with Deferred Reflections. This is part 13 of a tutorial series about rendering. The previous installment covered semitransparent shadows. Now we'll look at deferred shading. This tutorial was made with Unity 5.5.0f3. The anatomy of geometry. 1 Another Rendering Path Up to this point we've always used Unity's forward rendering path. But that's not the only rendering method that Unity supports. There's also the deferred path. And there are also the legacy vertex lit and the legacy deferred paths, but we won't cover those. So there is a deferred rendering path, but why would we bother with it? After all, we can render everything we want using the forward path. To answer that question, let's investigate their diferences. 1.1 Switching Paths Which rendering path is used is defined by the project-wide graphics settings. You can get there via Edit / Project Settings / Graphics. The rendering path and a few other settings are configured in three tiers. These tiers correspond to diferent categories of GPUs. The better the GPU, the higher a tier Unity uses. You can select which tier the editor uses via the Editor / Graphics Emulation submenu. Graphics settings, per tier. To change the rendering path, disable Use Defaults for the desired tier, then select either Forward or Deferred as the Rendering Path. 1.2 Comparing Draw Calls I'll use the Shadows Scene from the Rendering 7, Shadows tutorial to compare both approaches. -

What Is Game Engine Architecture
What Is Game Engine Architecture What Is Game Engine Architecture 1 / 2 In any case, game engines are the workhorses of modern videogame development As you'd expect, there are plenty of engines out there, from very well-known names like Quake and Unreal, that developers and publishers can license at considerable expense, through to in-house proprietary engines created by studios specifically for their own titles.. Quite a few of the in-house engines have no public personality and thus are not included on this list.. CryENGINEAs Seen In: Far Cry, Crysis, Crysis Warhead, Crysis 2, Aion: Tower of Eternity It didn't take long for the German developer Crytek to make a name for itself.. These are what turn good creative ideas into great gameplay Note: It is important to understand that not all developers are vocal about their game engines and instead play their cards close to their chests. T A L K E R to usher in a new generation of PC gaming, Crytek beat them all to the punch with a stunning, tropical set FPS game powered by its own brilliant CryENGINE.. 14320288/red-dead-redemption/videos/reddead_trl_wildwest_50509 html;jsessionid=1oyv5eo9s1id0' target='_blank'>Click here to see just how stunning Red Dead Redemption looks..

Typeset in LATEX Gothenburg, Sweden 2016 iii Generating Real Time Reflections by Ray Tracing Approximated Geometry Johan Fredriksson, Adam Scott Department of Interaction Design and Technologies Chalmers University of Technology Abstract Rendering reflections in real time is important for realistic modern games. A com- mon way to provide reflections is by using environment mapping. This method is not an accurate way to calculate reflections and it consumes a lot of memory space. We propose a method of ray tracing approximate geometry in real time. By using approximate geometry it can be kept simple and the size of the bounding volume hierarchy will have a lower memory impact. The ray tracing is performed on the GPU and the bounding volumes are pre built on the CPU using surface area heuris- tics.
