Khronos Releases OpenCL 2.1 Provisional Specification for Public Review

Mar 03, 2015 | Categories: Developers | Comments

The Khronos Group today announced the ratification and public release of the OpenCL 2.1 provisional specification. OpenCL 2.1 is a significant evolution of the open, royalty-free standard for heterogeneous parallel programming that defines a new kernel language based on a subset of C++ for significantly enhanced programmer productivity, and support for the new Khronos SPIR-V cross-API shader program intermediate language now used by both OpenCL and the new Vulkan graphics API.

Khronos Reveals Vulkan API for High-efficiency Graphics and Compute on GPUs

Mar 03, 2015 | Categories: Developers | Comments

The Khronos Group announced the availability of technical previews of the new Vulkan™ open standard API for high-efficiency access to graphics and compute on modern GPUs used in a wide variety of devices. This ground-up design, previously referred to as the Next Generation OpenGL Initiative, provides applications direct control over GPU acceleration for maximized performance and predictability, and uses Khronos’ new SPIR-V™ specification for shading language flexibility. Vulkan initial specifications and implementations are expected later this year and any company may participate in Vulkan’s ongoing development by joining Khronos.

GDC 2015: Khronos Group sessions for Next Generation of Graphics and OpenCL

Mar 02, 2015 | Categories: Developers | Comments

Are you going to GDC? Be sure to reserve your spot for glNext and OpenCL sessions happening off-site at GDC. The OpenCL sessions are almost full, as is the noon glNext session. You may register on the Khronos Group event page.

OpenGL hardware database with new features and now open source

Mar 02, 2015 | Categories: Developers | Comments

The OpenGL hardware database goes open source, with the client side application to generate and upload OpenGL hardware reports ported to C++ (using Qt as the UI framework). The client side application has been ported over from pascal to C++ for a broader audience and has been made open source, available on github. In addition to the move to C++, the application also adds lots of new information for OpenGL hardware reports, like added capabilities (reports now contain up to almost 200 implementation capabilities) compressed texture formats and a preview for displaying information gathered from gl_arb_internalformat_query2, making it an even more handy tool for OpenGL developers. Binaries are currently available for windows, Linux and Mac OS can be compiled from the sources with binary distributions to follow. Alongside with the move to open source, the web front end also got lots of new functionality, including new report layouts, advanced search and filter options and better ways to compare different OpenGL reports.

Qt3D 2.0 The FrameGraph

Feb 20, 2015 | Categories: Developers | Comments

KDAB are rewriting the Qt3D module of Qt 5 to provide an easy but flexible API for easily getting 3D content into your Qt applications using either C++ or QML. After reading this 4th article in the series, you will understand the difference between the Scenegraph and the Framegraph and see their respective uses. For the more adventurous amongst you, pick up a pre-release version of Qt3D and start experimenting to see what the Framegraph can do for you.

Tutorial: Persistent Mapped Buffers in OpenGL

Feb 17, 2015 | Categories: Developers | Comments

Summary of techniques to stream data from CPU to GPU in OpenGL with focusing on new method called persistent mapped buffers.

GDC 2015: Khronos Group sessions and the Next Generation of Graphics and Compute API

Feb 12, 2015 | Categories: General | Developers | Comments

The Khronos Group will be holding a number of sessions off-site during GDC week. There will be two sessions dedicated to discussing the Next Generation of Graphics and Compute API, as well as an OpenCL and WebGL meetup. These sessions will be taking place at SF Green Space (EEFG) just a few minutes walking distance from the Moscone center on Wednesday and Thursday. Registration is highly advised for the off-site sessions as space is limited and a good crowd is expected. Complete details are available on the Khronos GDC 2015 event page.

Substance 3D OpenGL rendering software is now free to use

Feb 02, 2015 | Categories: Applications | Comments

Substance 3D is a windows based application for rendering 3D photo realistic art using OpenGL. There are five OpenGL realtime visualization modes: Point clouds + skeleton, Soft (velvet-like), Dispersive (chromatic dispersion), Plaster (Ambient occlusion) and Specular (Global illumination). For optimal efficiency, Substance 3D uses multiple CPU-cores (if available) for GUI management, Shapes modeling calculations and Photorealistic rendering. As well, Substance 3D uses High Dynamic Range images (probes) as realtime lighting environment and can import up to 32 probes in its library.

3D Box Shot Pro V4 Release

Jan 28, 2015 | Categories: Developers | Comments

Jellypie Software has release 3D Box Shot Pro V4, an OpenGL powered 3D rendering tool. The new version now feature 128 models per scene, collision detection between models, stacking models and copy and paste functionality. It’s now possible to build complex scenes quickly and easily. 3D Box Shot Pro V4 features an all new OpenGL rendering engine that can render 67mega pixel images in seconds.

OpenGL works in biicode, a C/C++ dependency manager

Jan 28, 2015 | Categories: Developers | Comments

OpenGL can now be used with biicode (a C/C++ deps manager, just like Maven and Maven Central for Java) in any C and C++ project from source code. Other people have been using it with pretty good results.

GLEW 1.12.0 released

Jan 28, 2015 | Categories: Developers | Comments

GLEW is a cross-platform (Windows, Linux, Mac, Unix) open-source C/C++ extension loading library for OpenGL. GLEW 1.12.0 fixes some bugs and adds support for new extensions.

Piccante 0.4 the hottest HDR library with OpenGL support

Jan 28, 2015 | Categories: Developers | Comments

The new version of Piccante, a C++11 multi-platform (windows, mac os x, and linux) open-source (MPL license v2.0) imaging library, is now out! The new version provides a better support for OpenGL 4.0 Core Profile and novel algorithms on the GPU: improved memory management, image operators, better image statistics via redux, exposure fusion, Drago and Reinhard tone mapping operators, push-pull, edge-aware filtering, etc.

Overview of Qt3D 2.0 – Part 3 - Shadow Mapping

Jan 22, 2015 | Categories: Developers | Applications | Comments

KDAB are rewriting the Qt3D module of Qt 5 to provide an easy but flexible API for easily getting 3D content into your Qt applications using either C++ or QML. Qt3D is built on top of OpenGL and OpenGL ES and provides a data-driven renderer configuration. One of the biggest driving factors behind the design of Qt3D 2.0 is the ability to configure the renderer in order to accommodate custom rendering techniques. In this blog post I will explain how to render a scene in Qt3D with shadows.

NVIDIA has provided OpenGL and OpenGL ES examples

Jan 21, 2015 | Categories: Developers | Comments

NVIDIA has provided a set of OpenGL and OpenGL ES examples illustrating various techniques and features to use in your own code. The GameWorks examples are aimed more at game developers, and run on Windows, Linux and Android. They are broken down by topic. The “NVIDIA Professional Visualization” set of examples are OpenGL based, and aimed more at the professional workstation developers. The repository is new, so expect more samples to be published soon. Linux support is being worked on. You can find the examples on Github.
