GeeXLab - forum en français / Re: Updater un fragment shader
« on: June 11, 2017, 01:45:17 PM »
Hyperion, ca fait bien longtemps! Effectivement GeeXLab est la version un peu plus moderne de l'ancetre Hyperion.

Dans la version actuelle de GeeXLab, le live-coding existe pour les scripts Lua/Python (essentiellement les scripts FRAMES) et les shaders GLSL.

Pour les scripts deux facons de live-coder sont disponibles (sous Windows):
1/ menu Tools > Open built-in script live-updater.
2/ en codant le script FRAME dans un fichier lua/py séparée et en ajoutant l'attribut update_from_file_every_frame="1" dans le node script en XML. Dès qu'un changement est fait dans le fichier, le script est mis à jour.  Une demo est dispo dans le code sample pack (gl-21/live-coding/live-coding-02.xml)

Pour les shaders, une seule facon de live-coder existe sous Windows:
1/ menu Tools > Open built-in GPU program live-updater.

Pourquoi la seconde facon de live-coder les shaders n'existe pas? Aucune idée!  Je vais regarder l'ajout de cette fonctionnalité très prochainement.

Sinon en attendant, essaies la technique que tu as évoquée. Pour éviter de reloader le shader à chaque frame, ajoute un petit délai entre deux reloading, genre 1 seconde.

3D-Tech News Around The Web / (Demoscene) How a 64k intro is made
« on: May 22, 2017, 10:01:58 AM »
How is made the Guberniya 64k intro, released at the Revision 2017:

The demoscene is about producing cool real time works (as in “runs on your computer”) called demos. Some demos are really small, say 64 kilobytes or less, and these are called intros. The name comes from “crack intros”. So an intro is just a demo that’s small.

I’ve noticed many people have interest in demoscene productions but have no idea how they are actually made. This is a braindump/post-mortem of our recent 64k intro Guberniya and I hope that it will be interesting to newcomers and seasoned veterans alike. This article touches basically all techniques used in the demo and should give you an idea what goes into making one. I refer to people with their nick names in this article because that’s what sceners do.

During the Financial Analyst Day, AMD has unveiled plans about the next gen CPU and GPU architectures:


May 16, 2017 – IWOCL 2017, Toronto – The Khronos™ Group, an open consortium of leading hardware and software companies, announces the immediate availability of the finalized OpenCL™ 2.2 specification, incorporating industry feedback received from developers during the provisional specification review period. In addition to releasing the specification in final form, Khronos has, for the first time, released the full source of the specifications and conformance tests for OpenCL 2.2 onto GitHub to enable deeper community engagement. The conformance tests for OpenCL versions 1.2, 2.0 and 2.1 have also been released on GitHub with more open-source releases to follow.

OpenCL 2.2 brings the most developer-requested feature into core — the new OpenCL C++ kernel language for significantly enhanced parallel programming productivity. OpenCL™ 2.2 has been released in parallel with SPIR-V 1.2 which brings full support for the new OpenCL C++ kernel language into the Khronos-defined intermediate language. OpenCL 2.2 finalization further complements SYCL 2.2, which leverages OpenCL 2.2 to provide the power of single source C++ programming.

“By finalizing OpenCL 2.2, Khronos has delivered on its promise to make C++ a first-class kernel language in the OpenCL standard,” said Neil Trevett, OpenCL chair and Khronos president. “The OpenCL working group is now free to continue its work with SYCL, to converge the power of single source parallel C++ programming with standard ISO C++, and to explore new markets and opportunities for OpenCL — such as embedded vision and inferencing. We are also working to converge with, and leverage, the Khronos Vulkan API — merging advance graphics and compute into a single API.”

Khronos is proud to announce these new features at the IWOCL 2017 Conference, hosted at the University of Toronto and sponsored by the Fields Institute, in Toronto, Canada, where participants have a choice of four tutorials, 19 technical sessions, a Khronos panel discussion, posters, demos, and a conference dinner and networking event. The Khronos Group, alongside other Khronos Group Members, is the primary sponsor of IWOCL.

About OpenCL 2.2

OpenCL 2.2 defines the OpenCL C++ kernel language as a static subset of the C++14 standard. OpenCL C++ includes classes, templates, lambda expressions, function overloads and many other constructs to increase parallel programming productivity through generic and meta-programming.

OpenCL library functions can now take advantage of the C++ language to provide increased safety and reduced undefined behavior while accessing features such as atomics, iterators, images, samplers, pipes, and device queue built-in types and address spaces.

Pipe storage is a new device-side type in OpenCL 2.2 that is useful for FPGA implementations by making connectivity size and type known at compile time, enabling efficient device-scope communication between kernels.

OpenCL 2.2 also includes features for enhanced optimization of generated code: applications can provide the value of specialization constants at SPIR-V compilation time, a new query can detect non-trivial constructors and destructors of program scope global objects, and user callbacks can be set at program release time.

About SPIR-V 1.2

SPIR-V (Standard Portable Intermediate Representation) is the first open standard, cross-API intermediate language for natively representing parallel compute and graphics. As well as supporting the OpenCL C++ kernel language, SPIR-V 1.2 adds support for runtime specialization of key tuning parameters in OpenCL 2.2 such as workgroup size.

About SYCL 2.2

SYCL lets developers easily accelerate C++ software on OpenCL devices. SYCL is used in artificial intelligence frameworks because it matches the single-source programming style that enables complex deep learning graphs to use accelerators efficiently. SYCL 2.2 adds the capabilities of OpenCL 2.2 to the SYCL specification.

The open-source C++ 17 Parallel STL for SYCL, hosted by Khronos, will enable the upcoming C++ standard to support OpenCL 2.2 features such as shared virtual memory, generic pointers and device-side enqueue.

OpenCL C++ and SYCL between them now provide developers the choice of two C++ approaches. For developers who want to separate their device-side kernel source code and their host code, the C++ kernel language can be the best option. This is the approach taken with OpenCL C today, as well as the widely-adopted approach taken by shaders in graphics software. The alternative approach, commonly called 'single-source' C++, is the approach taken by SYCL, CUDA, OpenMP and the C++ 17 Parallel STL. By specifying both SYCL and the C++ kernel language, Khronos provides developers maximum choice, while aligning the two specifications so that code can be easily shared between these complementary approaches.

Full press-release can be found HERE.

Geeks3D's GPU Tools / GPU Shark 0.10.x released
« on: May 15, 2017, 08:49:41 PM »

RecursiveBF is a lightweight C++ library for recursive bilateral filtering.

Recursive bilateral filtering (developed by Qingxiong Yang) is pretty fast compared with most edge-preserving filtering methods

- computational complexity is linear in both input size and dimensionality:
- takes about 43 ms to process a one megapixel color image (i7 1.8GHz & 4GB mem)
- about 18x faster than Fast high-dimensional filtering using the permutohedral lattice
- about 86x faster than Gaussian kd-trees for fast high-dimensional filtering
