EGL Eye: OpenGL Visualization without an X Server

• Tags: nvidia egl OpenGL

This post by Peter Messmer on the NVIDIA Parallel Forall blog provides the basic steps to create a (full) OpenGL context using EGL in a headless environment, with code examples. EGL context creation is particularly relevant for accelerated rendering on HPC systems or in a cloud environment, where context management via X11 is often times impractical. Applications include in situ visualization and CUDA/OpenGL interoperation.

Mesa 11.0 3D Graphics Library updated with many EGL fixes

• Tags: graphics egl mesa

Mesa 11.0.3–according to the internal release notes–is a major bugfix release that resolves the KDE and Weston regressions that have been introduced in the previous release of the software, Mesa 11.0.2. Additionally, Mesa 3D Graphics Library 11.0.3 has a great number of patches for EGL and includes numerous bugfixes, especially for the Intel i830, Intel i915, Intel i965, RadeonSI, and Nouveau graphics drivers, as well as various under-the-hood improvements. "Mesa 11.0.3 is now available. In the current release we have a bunch of EGL patches, mangledGL build fixes and a healthy amount of driver bugfixes - RadeonSI, Nouveau, Intel i915 and i965," says Emil Velikov, software release engineer for Collabora. "Last but not least, the KDE/Weston regression introduced with 11.0.2 has also been resolved."

The PowerVR Imaging Framework for Android with OpenCL and EGL

• Tags: GPU android framework egl OpenVX OpenCL Imagination

The PowerVR Imaging Framework for Android comprises a set of extensions to the OpenCL and EGL Application Programming Interfaces (APIs) that enable efficient interoperability of software running on PowerVR GPUs with other components such as a CPU, ISP and VDE. These extensions enable the construction of shared memory allocations and software pipelines across multiple hardware components with no redundant memory copies (termed zero-copy). The framework is integrated at the library layer of the Android software stack, enabling efficient interoperability between APIs such as OpenCL, OpenGL ES and emerging APIs such as OpenVX.

Computational photography with ImgTec PowerVR SGX GPU and Khronos OpenCL and EGL

• Tags: GPU egl OpenKCam OpenCL Imagination

Imagination Technologies has developed a set of extensions to allow image conversion on the fly, using the Khronos Groups OpenCL and EGL technology. ImgTec converts the camera YUV data to RGB using the OES_EGL_image_external extension, and then use PowerVR’s zero-copy functionality to directly access the camera texture data from OpenCL. Find the in-depth explanation on ImgTec's website.
