I never tested that kind of code but a code snippet with sub_data_read_1ui could be:

Code: [Select]
gh_gpu_buffer.map(ssbo, "GL_READ_ONLY")
x = gh_gpu_buffer.sub_data_read_1ui(ssbo, offset)
gh_gpu_buffer.unmap(ssbo)

Let me know if you need more help.

3D-Tech News Around The Web / Smart Rendering for Virtual Reality

"Researchers from Intel have been working on new methods for improving the rendering speed for modern wide-angle head-mounted displays like the Oculus Rift and Google Cardboard. Their approach makes use of the fact that because of the relatively cheap and lightweight lenses the distortion astigmatism happens: only the center area can be perceived very sharp, while with increasing distance from it, the perception gets more and more blurred. So what happens if you don't spend the same amount of calculations and quality for all pixels? The blog entry gives hints to future rendering architectures and shows performance numbers."

One week after NVIDIA disabled overclocking on their GeForce 900M mobility lineup, a representative of the company has reported that NVIDIA will be bringing back the disabled feature for their overclocking enthusiasts on the mobility front. On the GeForce Forums, he writes, "We heard from many of you that you would like this feature enabled again. So, we will again be enabling overclocking in our upcoming driver release next month for those affected notebooks. If you are eager to regain this capability right away, you can also revert back to 344.75."

"The Linux kernel sits at the core of all Linux-based operating systems and is produced in an open-source, multi-stakeholder process. It's a process that has evolved over the last two decades, with a steady flow of new developers pouring into the community and contributing code. In a new report released by The Linux Foundation Feb. 18, the pace of Linux code contribution is detailed with data looking at eight Linux kernel releases in 15 months—beginning with the Linux 3.11 kernel, released in September 2013, and ending with Linux 3.18, which debuted Dec. 8, 2014."

"The time has come to introduce you guys to a new Linux kernel-based operating system, designed for creative people who were searching for a good-looking, reliable, and modern distribution for all of their multimedia creation needs. Future Studio OS is based on a mix between Debian GNU/Linux Jessie and Sid, using a low-latency Linux kernel and the KDE4 desktop environment."

"Bodhi GNU/Linux is a Ubuntu-based distribution designed especially for Desktop computing and is best known for its elegant and lightweight nature. The Distribution philosophy is to provide a minimal base system that can be populated with the applications as per user’s choice. The base System only include those applications which are essentially required viz., ‘Etecad‘ File Manager, ‘Midori‘ web browser, ‘Terminology‘ terminal emulator, ePhoto and ePad. Apt or AppCenter can be used to download and install lightweight applications in one go."

3D-Tech News Around The Web / New features in Qt 5.5
« Last post by JeGX on February 20, 2015, 05:20:45 PM »
Qt 5.5 will be shipped soon and here is a lit of the new features:

Quote

...

- Qt 3D
    - The Qt 3D module is now included as a technology preview.

- Qt Canvas 3D
    - Added Qt Canvas 3D module, a JavaScript 3D rendering API for Qt Quick.


- Qt Multimedia
    -  GStreamer 1.0 support. Note that the default is still 0.10. 1.0 support can be enabled by configuring Qt with ‘-gstreamer 1.0’.

"The rate of Linux development is unmatched," the foundation said in an announcement accompanying the report. "In fact, Linux kernel 3.15 was the busiest development cycle in the kernel’s history. This rate of change continues to increase, as does the number of developers and companies involved in the process. The average number of changes accepted into the kernel per hour is 7.71, which translates to 185 changes every day and nearly 1,300 per week. The average days of development per release decreased from 70 days to 66 days."

...

Each Linux release includes more than 10,000 patches from more than 1,400 developers and more than 200 corporations. "Since the 2.6.11 release, the top ten developers have contributed 36,664 changes—8.2 percent of the total. The top thirty developers contributed just over 17 percent of the total," the report said.
