Qualcomm announces new VR dev kit and headset accelerator program

• Tags:

Qualcomm is preparing to launch a head-mounted display accelerator program which will give companies building VR headset access to part of Qualcomm’s supply chain partners alongside efforts related to product marketing. Qualcomm has also announced that they will be updating their development kit to highlight development focusing on the 835. The new dev kit will feature free motion 6DOF inside-out tracking based on a pair of cameras, and will also highlight new eye-tracking technologies that will lessen compute loads on the system. Qualcomm is one of the growing list of companies contributing to the Khronos Group Virtual Reality Standard Initiative.

Igalia contributions to Intel OpenGL 4.5 certified drivers

• Tags:

Igalia has contributed several features and bugfixes that helped achieve this important milestone. During the last several months, Igalia has been working hard on improving the Intel driver to enable 64-bit floating point support. We developed OpenGL extensions such as ARB_gpu_shader_fp64 and ARB_vertex_attrib_64bit, which were a major contributor to increasing the supported OpenGL version. As members of the Khronos Group, Igalia also had the opportunity to contribute tests and bugfixes to the conformance suite itself.

xeogl extended to load glTF models with PBR materials

• Tags:

Xeolabs developer Lindsay Kay this month extended xeogl to load glTF models with PBR materials, for both metallic/roughness and specular/glossiness work flows, using the FRAUNHOFER_materials_pbr extension. This is still a work in progress, as they are following along behind the current development of the glTF 2.0 spec. xeogl is a WebGL-based 3D engine that's geared towards visualization applications in science, technology, engineering and mathematics (STEM).

NVIDIA 378.66 drivers for Windows offer OpenCL 2.0 evaluation support

• Tags:

NVIDIA graphics driver for Windows version 378.66 is now offering some OpenCL 2.0 support. From the release notes: "New features in OpenCL 2.0 are available in the driver for evaluation purposes only." Some known issues include: The current implementation is limited to 64-bit platforms only; OpenCL 2.0 allows kernels to be enqueued with global_work_size larger than the compute capability of the NVIDIA GPU. The current implementation supports only combinations of global_work_size and local_work_size that are within the compute capability of the NVIDIA GPU; For executing kernels (whether from the host or the device), OpenCL 2.0 supports non-uniform ND-ranges where global_work_size does not need to be divisible by the local_work_size. This capability is not yet supported in the NVIDIA driver, and therefore not supported for device side kernel enqueues.
