Renderdoc™ is a standalone program that can be used to capture and replay frames from any Windows application using Direct3D 11.0 or 11.1, and provides tools for deep analysis and graphics inspection, as well as detailed examination of API usage - allowing developers to locate bugs and problems in their programs.

Developed by Crytek, Renderdoc™ has been built from the ground up to reflect the real needs of graphics programmers, and has evolved based on its day-to-day usage in the creation of CRYENGINE titles.

Plans are in place to increase Renderdoc™'s functionality over time, adding support for other platforms and APIs such as OpenGL.

The introduction this week of NVIDIA’s first-generation “Maxwell” GPUs is a very exciting moment for GPU computing. These first Maxwell products, such as the GeForce GTX 750 Ti, are based on the GM107 GPU and are designed for use in low-power environments such as notebooks and small form factor computers. What is exciting about this announcement for HPC and other GPU computing developers is the great leap in energy efficiency that Maxwell provides: nearly twice that of the Kepler GPU architecture. That makes Maxwell a great architecture for future NVIDIA Tesla products, so stay tuned.

This post will tell you 10 things that you need to know about Maxwell as a GPU computing programmer, including high-level benefits of the architecture, specifics of the new Maxwell multiprocessor, guidance on tuning and pointers to more resources.

With thousands of commits a week across hundreds of thousands of files, Facebook's main source repository is enormous--many times larger than even the Linux kernel, which checked in at 17 million lines of code and 44,000 files in 2013. Given our size and complexity—and Facebook's practice of shipping code twice a day--improving our source control is one way we help our engineers move fast.

Vivante Unveils Less than 1 mm2 OpenGL ES 2.0 GPU for Wearables and Internet of Things (IoT) Devices
07 October 2013

World’s tiniest GPU targets silicon vendors designing for the next billion smart devices

Sunnyvale, CA – October 7, 2013 –Vivante Corporation today announced an area-optimized version of its GC series OpenGL 2.0 ES GPU cores for Wearable and other IoT devices. Featuring the industry’s tiniest GPU core, less than one mm2, the GC 400 gives MCU/MPU silicon vendors a simple plug-in solution and complete IoT software stack that easily adds full-featured smartphone graphics capabilities to any product line.

Microchip, one of the leaders in MCU/MPU solutions and an important player in IoT, recently said, “during the past few years, the evolution in user interface technology was very rapid from touch keys to touchless interface driven by the consumer market, but it also happened in every type of application and market. The user interface is now a key product differentiator.”

IoT solutions ranging from home automation (HA), security, and appliances, to medical electronics and monitoring systems/sensors will require a GPU to create compelling user interface (UI) and establish product differentiation. Vivante’s IoT GC400 core allows end products to be beautifully crafted and visually intelligent, all while providing a seamless user experience (UX) across devices.   

“According to Cisco’s IBSG group, they predict “there will be 25 billion devices connected to the internet by 2015 and 50 billion by 2020,” said Wei-Jin Dai, Vivante President and CEO. “This huge number of interconnected smart devices represents an enormous opportunity for the GPU to make the impersonal device personable and offer a great user experience from the TV to the smartphone through to the breadth of IoT devices with screens of any size.”

As cited in a recent article by Bloomberg Technology,“Android is becoming the standard operating system for the “Internet of Things”—Silicon Valley’s voguish term for the expanding interconnectedness of smart devices, ranging from sensors in your shoe to jet engine monitors...Every screen variant, mobile chip, and sensor known to man has been tuned to work with Android.” Google’s Android has all the qualities, next generation features, and roadmap needed to support the vast amount of web interconnected products imaginable. A key element with Android in IoT is the visual centric nature of the OS that requires a tiny, full featured graphics processor to drive the device screen.

Gaijin Entertainment, the developers of War Thunder recently claimed that the PS4’s GPU is 40% more powerful than the Xbox One. So we made sure to ask about the console’s GPU and whether it’s eased out the number of things you can do on screen in the game.

“From a pure tech perspective it’s undeniable that the PS4 GPU will make it the most powerful console in the world and for us that means we can turn on every visual flourish we want while keeping a smooth & responsive 60fps. We’re focused on every version running at 60fps including Vita, frame rate is king.”

Origin PC CEO and co-founder Kevin Wasielewski told us that the company is no longer offering AMD GPUs in its systems and will solely provide NVIDIA graphics options. His reasons were initially vague: “This decision was based on a combination of many factors including customer experiences, GPU performance/drivers/stability, and requests from our support staff. Based on our 15+ years of experience building and selling award winning high-performance PCs, we strongly feel the best PC gaming experience is on NVIDIA GPUs,” he said.

What is K3D.js?

Quote
K3D is JavaScript library for working with 3D meshes. K3D is not a rendering engine!

K3D.js can be used for different operations with 3D meshes:

    converting between different formats
    applying affine and other transformations
    generating primitive objects
    creating LODs

To use K3D, you should have a basic knowledge of 3D meshes, index / vertex coordinate arrays etc.

3D-Tech News Around The Web / Decyphering the Business Card Raytracer

I recently came across Paul Heckbert's business card raytracer. For those that have never heard of it: It is a very famous challenge in the Computer Graphics field that started on May 4th, 1984 via a post on comp.graphics by Paul Heckbert ( More about this in his article "A Minimal Ray Tracer" from the book Graphics Gems IV).

The goal was to produce the source code for a raytracer...that would fit on the back of a business card.

Code: [Select]

3D-Tech News Around The Web / AMD R9 290X GPU Specs Revealed
« on: September 19, 2013, 02:20:41 PM »
Quote
With an estimated die-area of 430 mm² (18% bigger than "Tahiti,") the chip physically features 2,816 stream processors (SPs) spread across 44 clusters with 64 SPs each (a 37.5% increase over "Tahiti"). The chip features four independent raster engines, compared to two independent ones on "Tahiti." This could translate into double the geometry processing muscle as "Tahiti," with four independent tessellation units. The memory interface of the chip is expected to be 384-bit wide, based on the GDDR5 specification. Given the way TMUs are arranged on chips based on this architecture, one can deduce 176 TMUs on the chip. The ROP count could be 32 or 48. The chip will feature hardware support for DirectX 11.2, including the much hyped shared resources (mega-texture) feature.
