3D-Tech News Around The Web / DirectX 12: A Major Stride for Gaming
« on: March 20, 2014, 07:23:01 PM »
Microsoft today introduced DirectX 12 at the annual Game Developers Conference (GDC) in San Francisco. DX12 is Microsoft’s latest version of the graphics API that is the dominant standard in the growing, $25 billion PC gaming industry.

Developers have been asking for a thinner, more efficient API that allows them to control hardware resources more directly. Despite significant efficiency improvements delivered by continuous advancement of existing API implementations, next-generation applications want to extract all possible performance from multi-core systems. Developers also want to take direct advantage of advanced GPU hardware features, from which developers are currently insulated to provide fool-proof usage. DirectX 12 was designed from scratch to provide the infrastructure for these advanced applications.

3D-Tech News Around The Web / Blender 2.70 Final is Now Available
« on: March 20, 2014, 05:55:10 PM »
After two release candidates, the Blender Foundation has now released Blender 2.70.

The official release still don't support CUDA sm5.0 kernels.
Blender Artists to the rescue:

Quote from: Rolf
Bug is fixed and 2.70 is out now, so here some updates
Blender 2.70 64-bit Windows with sm_50 kernel Hash: cc2cdfb

Blender 2.70 32-bit Windows with sm_50 kernel Hash 19fcb4d

and for testing a special sm_50 kernel, this kernel enabled subsurface scattering and volume scatter/absorption on 750/ti, only for 64bit.
Vram usage is much higher with this kernel.
Put this file to ...Blender\2.70\scripts\addons\cycles\lib\

Quote from: JuicyFruit
I have also compiled sm_50 kernels for release (both 32 bit and 64 bit)

PowerVR Wizard brings ray tracing to real-time graphics

Today at GDC, the firm announced that its PowerVR Wizard GR6500 graphics processor IP is available for licensing, and it also revealed a major software alliance to enable game developers to take advantage of Wizard's custom ray-tracing hardware.

The Wizard GPU is based on the PowerVR Rogue graphics processor that we're pretty darned certain resides in Apple's latest phones and tablets. More specifically, the PowerVR GR6500 is a ray-tracing enabled version of the PowerVR Series6XT Rogue core...

Crytek Adds NVIDIA GameWorks to “Warface”

We’re announcing today at the Game Developers Conference, in San Francisco, that we’ve teamed up with Crytek to add support for several NVIDIA GameWorks technologies to its hit free-to-play online first-person shooter “Warface,” powered by CRYENGINE, their award-winning game development solution.

CRYENGINE has been praised for over a decade for its advanced technology. It’s the framework behind Crytek’s own hit franchises, including “Crysis” and “Ryse: Son of Rome.” It’s also licensed to top developers, such as NCsoft, XL Games, Tencent and 2K Games.

“Warface” uses CRYENGINE’s advanced graphics and game technology to create a fast-paced, online first-person shooter, featuring intuitive controls and slick gameplay. The addition of GameWorks technologies like NVIDIA PhysX and VisualFX will take the gameplay in “Warface” to a higher plane of realism and engagement.

The Khronos Group today announced a number of new and significant updates to its portfolio of open, royalty free industry standards that enable the authoring and acceleration of parallel computing, graphics, vision, sensor processing and dynamic media on a wide variety of platforms and devices:

    OpenGL® ES 3.1 Specification Released – The next leap in mobile & embedded graphics
    WebCL™ 1.0 Specification Released – Browser-based heterogeneous compute acceleration
    SYCL™ 1.2 Provisional Specification Released – Enabling high-level C++ tools for OpenCL
    OpenCL™ 2.0 Adopters Program Launched – Driving OpenCL 2.0 conformance
    EGL™ 1.5 Specification Released – The essential glue for secure, integrated API rendering

AMD is probably already working on OpenCL 2.0 - at least the recent Catalysts come with Khronos OpenCL ICD 2.0 (OPENCL.DLL)

Unity 5!
Today, at the biggest show in the game development industry, we threw the veil off of Unity 5 and announced that it’s coming this year! This release is about combining all perspectives of game development together. We’re adding crazy fancy middleware to Unity, helping you out with your business, optimizing the engine dramatically, creating better workflows and filling gaps where we knew we could do better.

The February UDK update is here!

In this new release of UDK, the free edition of Unreal Engine 3, developers will benefit from enhancements specific to mobile development, including iOS 7 and Xcode 5 support, shader upgrades, as well as the addition of distortion.

Optimizations to the Unreal Editor, tools, post-process features and Mac packager also ship in this build.

NVIDIA overhauled their developer website, everything not CUDA SDK related is now available here:

The sample demonstrates shallow water solver implemented with the OpenCL™ technology. The Shallow Water sample relies on flux splitting method for solving the approximated Navier-Stokes equations. The algorithm operates on 2D maps of velocity and height, calculates updated maps for the next time step. The updated maps are rendered with pixel and vertex shaders (Microsoft DirectX* 10).

CUDA 6 introduces Unified Memory, which dramatically simplifies memory management for GPU computing. Now you can focus on writing parallel kernels when porting code to the GPU, and memory management becomes an optimization.

The CUDA 6 Release Candidate is now publicly available. In today’s CUDACast, I will show you some simple examples showing how easy it is to accelerate code on the GPU using Unified Memory in CUDA 6, and how powerful Unified Memory is for sharing C++ data structures between host and device code.

3D-Tech News Around The Web / AMD releases Chrome browser with WebCL
« on: March 15, 2014, 08:38:49 AM »
Chrome web Browser with WebCL™ now Available for Download
WebCL™ 1.0, soon to be published by the Khronos group, is a JavaScript API providing access to OpenCL™ acceleration, a sibling to the now quite popular WebGL™ API. AMD has been working on implementing WebCL™ inside a Chrome browser, enabling web programmer access to compute acceleration, including interop between WebCL™ and WebGL™.

It seems to be incompatible with NOKIA's WebCL?
