Leadwerks Software announces glTF support in upcoming engine

• Tags:

Leadwerks Software has announced version 5 of their 3D engine will rely on glTF as its main 3D model format. According to the company, the readability of glTF files, its widespread adoption, the well-defined PBR material system, and the availability of game-ready models in glTF format all influenced the decision to move away from custom file formats. glTF will function as a mechanism for getting content into the new engine, but will also serve as the final runtime format for published games, eliminating any conversion step in the new art pipeline. The company is advising partners to begin learning the glTF art pipeline for their 3D modeling package in preparation for the new software.

In these days of social distancing, game developers and content creators all over the world are working from home and asking for help using Windows Remote Desktop streaming with the OpenGL tools they use.

NVIDIA has created a special tool for GeForce GPUs to accelerate Windows Remote Desktop streaming with GeForce drivers R440 or later.

Download and run the executable (nvidiaopenglrdp.exe) from the DesignWorks website as Administrator on the remote Windows PC where your OpenGL application will run. A dialog will confirm that OpenGL acceleration is enabled for Remote Desktop and if a reboot is required.

Portable Computing Language (PoCL) v1.5 released

• Tags: opencl

PoCL is a portable open source (MIT-licensed) implementation of the OpenCL standard (1.2 with some 2.0 features supported). In addition to being an
easily portable multi-device open-source OpenCL implementation, a major goal of this project is improving interoperability of diversity of
OpenCL-capable devices by integrating them to a single centrally orchestrated platform. Upstream PoCL currently supports various CPUs, NVIDIA GPUs via libcuda, HSA-supported GPUs and TCE ASIPs (experimental, see: http://openasip.org) It also is known to have multiple (private) ports. 1.5 release adds support for Clang/LLVM 10.0, easy to use kernel profiling features and plenty of fixes and performance improvements.

HIPCL: From CUDA to OpenCL Execution

• Tags: opencl cuda

Heterogeneous-Compute Interface for Portability (HIP) is a runtime API and a conversion tool to help make CUDA programs more portable. It was originally contributed by AMD to the open source community with the intention to ease the effort of making CUDA applications also work on AMD’s ROCm platform.

While AMD and NVIDIA share the vast majority of the discrete GPU market, it is useful to make this “CUDA portability enhancement route” available to an even wider set of platforms. Since the Khronos OpenCL standard remains the most widely adopted cross-platform heterogeneous programming API/middleware, it is interesting to study whether HIP could be ported on top of it, expanding its scope potentially to all OpenCL supported devices. We in Customized Parallel Computing group, Tampere University, Finland, are happy to announce that to have worked on such a tool, known as HIPCL, for some time and it’s now published and available in Github.

The first release of HIPCL is a proof-of-concept, but is already useful for end-users. It can run most of the CUDA examples in the HIP repository and the list of supported CUDA applications will grow steadily as we add new features.
