This is something I'd like to highlight and stress the importance of - without the portability of Vulkan we would have been forced to implement a special Metal rendering backend just for macOS users, something not doable for a relatively small company such as ours.

  • The State of Vulkan on Apple 03June 2021
    The State of Vulkan on Apple Devices Why you should be developing for the Apple ecosystem with Vulkan, and how to do it. Richard S. Wright Jr., LunarG June 3, 2021 If you are reading this, you likely already know what Vulkan is -- a low-overhead, high-performance, cross-platform, graphics and compute API designed to take maximum advantage of today's highly parallel and scalable graphics and compute hardware. To be sure, there are other APIs with this goal such as Microsoft’s DirectX and Apple’s Metal API. For a long time OpenGL matured to meet the needs of rapidly evolving hardware and met well the challenges of cross-platform development of high-performance graphics applications. OpenGL will remain viable for a very long time for many applications (and can actually be layered on top of Vulkan), but to take maximum advantage of modern hardware, a new and somewhat reinvented approach is called for. Everyone does not need the level of control that Vulkan provides, but if you do, you can think of Vulkan as a lower-level successor to OpenGL in that it attempts to enable highly portable, yet high-performance, application development across desktop and mobile device platforms. Writing platform specific code does have its advantages, and vendors such as Microsoft and Apple certainly adore having best of breed titles available exclusively for their customers as it adds value to their ecosystem. For developers though, it is often in our best interests to make our products available as widely as possible. Aside from gaming consoles with their mostly closed development environments, Windows, Linux, Apple, and Android combined represent most of the market for developers of end user software and games today.

Graphics programming, at least in Finland, does not have much literature written for it. The purpose of this report is to examine how the graphics programming has evolved from the old times to modern times, and examine how the tools for writing graphics programming has changed. The author applied background knowledge learned in school and in free time about the research. The work was carried out by using the internet with search engines and online documentation searches. A variety of books, videos, articles and documentation pages were used as materials. The main results are a brief overview on the differences in graphics programming from the old times to modern times, descriptions on the areas graphics programming handles and a small example on the implementation of graphics program.

  • Compute Shader in Image Processing Development∗
    Compute Shader in Image Processing Development∗ Robert Tornai, Péter Fürjes-Benke University of Debrecen, Faculty of Informatics [email protected] [email protected] Proceedings of the 1st Conference on Information Technology and Data Science Debrecen, Hungary, November 6–8, 2020 published at http://ceur-ws.org Abstract This paper will present the OpenGL compute shader implementation of the BlackRoom software. BlackRoom is a platform-independent image pro- cessing program, which supports multiple execution branches like Vulkan fragment shader, OpenGL fragment shader, and CPU-based rendering. In order to support a wider range of devices with different amounts of mem- ory, users can utilize tile rendering, and the program can be run in browsers thanks to the WebAssembly format. Thanks to our program’s built-in benchmark system, the performance dif- ferences between the implemented CPU- and GPU-based executing branches can be easily determined. We made a comprehensive comparison between the rendering performance of our CPU, OpenGL compute shader, fragment shader and Vulkan fragment shader branches. Latter is under development, which induces a relatively higher runtime presently. A further aim is to optimize our algorithms, which are using Vulkan API. Besides that, the program will be capable of rendering multiple effects at once with Vulkan fragment shader. Furthermore, the available GPU rendering and multi-threading features are planned to be enabled for WebAssembly platform yielded by the Qt framework [2].

  • Putting Randomized Compiler Testing Into Production

Donaldson 4 Google, UK 5 Imperial College London, UK 6 [email protected] 7 Hugues Evrard 8 Google, UK 9 [email protected] 10 Paul Thomson 11 Google, UK 12 [email protected] 13 Abstract 14 We describe our experience over the last 18 months on a compiler testing technology transfer project: 15 taking the GraphicsFuzz research project on randomized metamorphic testing of graphics shader 16 compilers, and building the necessary tooling around it to provide a highly automated process 17 for improving the Khronos Vulkan Conformance Test Suite (CTS) with test cases that expose 18 fuzzer-found compiler bugs, or that plug gaps in test coverage. We present this tooling for test 19 automation—gfauto—in detail, as well as our use of differential coverage and test case reduction 20 as a method for automatically synthesizing tests that fill coverage gaps. We explain the value 21 that GraphicsFuzz has provided in automatically testing the ecosystem of tools for transforming, 22 optimizing and validating Vulkan shaders, and the challenges faced when testing a tool ecosystem 23 rather than a single tool. We discuss practical issues associated with putting automated metamorphic 24 testing into production, related to test case validity, bug de-duplication and floating-point precision, 25 and and provide illustrative examples of bugs found during our work. 26 2012 ACM Subject Classification Software and its engineering → Compilers; Software and its 27 engineering → Software testing and debugging 28 Keywords and phrases Compilers, metamorphic testing, 3D graphics, experience report 29 Digital Object Identifier 10.4230/LIPIcs.ECOOP.2020.22 30 Category Experience Report 31 1 Introduction 32 Graphics processing units (GPUs) provide hardware-accelerated graphics in many scenarios, 33 such as 3D and 2D games, applications, web browsers, and operating system user interfaces.

  • Evulkan; a Vulkan Graphics Library
    Bournemouth University National Centre for Computer Animation MSc in Computer Animation and Visual Effects evulkan A Vulkan Graphics Library Eimear Crotty github.com/eimearc/masters August 2020 Abstract Vulkan is a low-level graphics and compute API which aims to provide users with faster draw speeds by removing overhead from the driver. The user is expected to explicitly provide the details previously generated by the driver. The resulting extra code can be difficult to understand and taxing to write for beginners, leading to the need for a helper library. i Acknowledgements Thanks to Jon Macey for his help on the C++ side of things and for loaning me his Vulkan book. Many thanks to my uncle Neil for giving me a second home during the year. Those curries and trips to the Glasshouse kept me going through multiple challenging assign- ments. I’m sorry they were cut short. Finally, thanks to my mum Kerry, dad Owen, siblings Rory, Aisling, Aoife and Ellie for their support during the last year. ii Contents 1 Introduction1 2 Previous Work2 2.1 V-EZ....................................2 2.2 Anvil....................................2 2.3 GLOVE...................................2 2.4 MoltenVK.................................3 2.5 Personal Inquiry..............................3 3 Technical Background4 3.1 Useful Resources..............................4 3.2 Comparison with OpenGL.........................4 3.3 Vulkan Layers...............................5 3.3.1 Loader...............................5 3.3.2 Dispatch Chains..........................6 3.4 Vulkan Components............................7 3.4.1 VkInstance.............................7 3.4.2 VkPhysicalDevice.........................8 3.4.3 VkDevice..............................8 3.4.4 VkQueue..............................8 3.4.5 VkDeviceMemory.........................8 3.4.6 VkCommandBuffer.........................9 3.4.7 VkSwapchainKHR.........................9 3.5 Vulkan Object Model..........................

  • Rpcs3 Older Version Download RPCS3
    rpcs3 older version download RPCS3. RPCS3 is a PlayStation 3 emulator for Windows with which you'll be able to bring back to life all the best games for this console, now on your computer. 1 2 3 4 5 6 7 8 9 10. The PlayStation 3 video console was released back in 2006 and was discontinued eleven years later to the benefit of its successor, the PS4. Nevertheless, just like with other video consoles, there are several emulators for Windows to be able to bring this platform back to life, and one of them is this RPCS3 . Bring back your favorite PS3 games. It's an open-source emulator with a very clear and functional design that can load titles for this video console in PKG format . although the ideal thing to do is to resort to your old PS3 games as it's the best and most reliable way of doing so, as pointed out by the developers. It supports both mouse and keyboard controls as well as Dualshock 4 gamepads. Regarding the emulator's stability, as usual in these cases, it's not so much about the software's development but more about the game itself. That's why we may come across some titles that don't run correctly or at least as smoothly as we'd like. The developers are working hard to adapt each new version of the emulator to each case whenever possible. don't forget that we're talking about a development at alpha stage. RPCS3 0.0.3 (2017-09-22) RPCS3 is an open-source Sony PlayStation 3 emulator and debugger written in C++ for Windows and Linux.
