October 20th, 2014, – The Khronos™ Group today announced the ratification and public release of the finalized OpenVX™ 1.0 specification, an open, royalty-free standard for cross platform acceleration of computer vision applications. OpenVX enables performance and power-optimized computer vision processing, especially important in embedded and real-time uses cases such as face, body and gesture tracking, smart video surveillance, advanced driver assistance systems (ADAS), object and scene reconstruction, augmented reality, visual inspection, robotics and more. In addition to the OpenVX specification, Khronos has developed a full set of conformance tests and an Adopters Program, that enables implementers to test their implementations and use the OpenVX trademark if conformant. Khronos plans to ship an open source, fully-conformant CPU-based implementation of OpenVX 1.0 before the end of 2014. The full OpenVX 1.0 specification and details about the OpenVX Adopters Program are available at www.khronos.org/openvx.
OpenVX defines a higher level of abstraction for execution and memory models than compute frameworks such as OpenCL™, enabling significant implementation innovation and efficient execution on a wide range of architectures while maintaining a consistent vision acceleration API for application portability. An OpenVX developer expresses a connected graph of vision nodes that an implementer can execute and optimize through a wide variety of techniques such as: acceleration on CPUs, GPUs, DSPs or dedicated hardware, compiler optimizations, node coalescing, and tiled execution to keep sections of processed images in local memories. This architectural agility enables OpenVX applications on a diversity of systems optimized for different levels of power and performance, including very battery-sensitive, vision-enabled, wearable displays.
“Increasingly powerful and efficient processors and image sensors are enabling engineers to incorporate visual intelligence into a wide range of systems and applications,” said Jeff Bier, founder of the Embedded Vision Alliance. “A key challenge for engineers is efficiently mapping complex algorithms onto the processor best suited to the application. OpenVX is an important step towards easing this challenge.”
The precisely defined specification and conformance tests for OpenVX make it ideal for deployment in production systems, where cross-vendor consistency and reliability are essential. OpenVX is complementary to the popular OpenCV open source vision library that is also used for application prototyping but is not so tightly defined and lacks OpenVX graph optimizations. Khronos has defined the VXU™ utility library to enable developers to call individual OpenVX nodes as standalone functions for efficient code migration from traditional vision libraries such as OpenCV. Finally, as any Khronos specification, OpenVX is extensible to enable nodes to be defined and deployed to meet customer needs, ahead of being integrated into the core specification.Quote

qu3e is a compact, light-weight and fast 3D physics engine in C++. It is has been specifically created to be used in games. It is portable with no external dependencies other than various standard c header files (such as cassert and cmath). qu3e is designed to have an extremely simple interface for creating and manipulating rigid bodies.
qu3e is of particular interest to those in need of a fast and simple 3D physics engine, without spending too much time learning about how the whole engine works. In order to keep things very simple and friendly for new users, only box collision is supported. No other shapes are supported (capsules and spheres may be added in the future if requested).
Since qu3e is written in C++ is intended for users familiar with C++. The inner-code of qu3e has quite a few comments and is a great place for users to learn the workings of a 3D physics engine.
qu3e stands for "cube", since the 3 looks slightly like the letter b and boxes (or cubes!) are the primary type of collision object.

I am extremely happy to announce that Qt 5.4 Beta is now available for download. There are a lot of new and interesting things in Qt 5.4 and I will try to summarize the most important highlights in this blog post.
Qt 5.4 brings capability to dynamically select during the application startup whether to use ANGLE or OpenGL on Windows. It is possible to use either opengl32.dll or ANGLE’s OpenGL ES 2.0 implementation in Qt applications without the need for two separate builds of the binaries. This significantly simplifies the task of creating Qt Quick applications for Windows PCs. Dynamic GL switching is not yet enabled in the prebuilt Qt 5.4 Beta binaries. In addition to these, there is a large number of smaller improvements and bug fixes for the Windows port in Qt 5.4.
QOpenGLContext is now able to adopt existing native contexts (EGL, GLX, …). This allows interoperability between Qt and other frameworks, such as game engines.
Version 0.7.1.5 - 2014.10.10
! updated pixel format support for image2D writing (GL_ARB_shader_image_load_store)
PF_U8_RGBA (rgba8 in GLSL) and PF_U8_R (r8 in GLSL) added (gh_texture.image_bind()).
Version 0.7.1.4 - 2014.10.10

Version 0.7.1.3 - 2014.10.05
+ added webcam_get_num() to the gh_utils lib (Lua/Python).
! improved the management of multiple webcams in the Windows version.
Version 0.7.1.2 - 2014.10.04
* bugfix: crash when ZOMBIE scripts are stored in separate file
instead of in the XML.
+ added network_message_pop() to gh_utils.
When it comes to AMD FirePro™ S-Series GPUs, there is never “too much of a good thing.” During my conversations at trade shows and conventions, customers have been asking for a server GPU solution that not only provides the speed to accomplish computational tasks, but they also want accuracy for precise results. Earlier this year, we announced the top-of-line AMD FirePro™ S9150 – the most powerful server GPU ever built for High Performance Computing1 measured by performance/watt. But customers also told us they want a product for mainstream, budget conscious projects that still delivers equally exceptional performance for HPC.
To meet that demand, we’ve expanded our server GPU portfolio. By infusing our most current iteration of the AMD GCN architecture2 into AMD FirePro™ server GPUs, we have been able to offer two products that deliver leading edge double-precision floating-point rates, and operate with tremendous efficiency.
The new AMD FirePro™ S9100 server GPU is supreme in its class, with high peak single- and double-precision floating point performance, including 2.11 TFLOPS peak double-precision and up to 9.4 GFLOPS per watt TDP double-precision performance3. Compute-intensive workloads are where this card excels. With 2,560 stream processors and 12GB of GDDR5 memory, the AMD FirePro S9100 is equipped to handle supercomputing tasks. For those working in scientific compute, research, or structural analysis, it would be fair to say this GPU is a compute powerhouse. On top of the performance, the card’s maximum TDP comes in at 225W, and its passive cooling solution makes it ideal for deployment in server environments.

- GL_NV_framebuffer_mixed_samples and GL_EXT_raster_multisample - target-independent multisampling control and mixed samples: this feature adds a lot of flexibility to the multi-sampled rasterization, and decouples the rasterization sampling frequency (which can be set explicitly) from the actual framebuffer storage. It enables rasterization to operate at higher sampling frequency than the number of samples in the target color render buffers, and it supports both depth and stencil testing at this frequency, if the corresponding depth and stencil buffers are sampled accordingly (it must be a multiple of the number of samples in the color buffers).
- GL_NV_fragment_coverage_to_color - coverage to color conversion: this allows using ROP to automatically convert the post depth-/stencil-/alpha- test coverage mask into a color and write it into a color render target.
- GL_EXT_post_depth_coverage - post-depth coverage: this extension allows the fragment shader to get the post depth-test coverage mask of the current fragment as input (gl_SampleMaskIn).
- GL_NV_sample_mask_override_coverage - multisample coverage override: the standard GL behavior for FS output coverage mask (gl_SampleMask) is to AND it with the actual primitive input coverage mask. This extension disables this operation.
- GL_NV_sample_locations - programmable sample locations: Allows applications to explicitly set the location of sub-pixel samples for multisample rasterization, providing fully programmable sampling patterns.
- GL_NV_conservative_raster - conservative rasterization: It allows rasterization to generate fragments for any pixel touched by a triangle, even if no sample location is covered on the pixel.
- GL_NV_fragment_shader_interlock - fragment shader interlock: This extension exposes an hardware-accelerate critical section for the fragment shader, allowing hazard-free read-modify-write operations on a per-pixel basis.
- GL_NV_fill_rectangle: screen-space bounding-box rasterization: this allows rasterizing the axis-aligned screen-space bounding box of submitted triangles, disregarding the actual triangle edges.
- GL_NV_geometry_shader_passthrough - geometry shader passthrough: this extension allows to write more efficient geometry shaders in the case there is a one-to-one mapping between input and output primitives.
- GL_EXT_sparse_texture2: Enhanced sparse textures: this new extension adds the ability to retrieve texture access residency information from GLSL, to specify minimum allocated LOD to texture fetches and to return a constant zero value for lookups into unallocated pages.
- GL_EXT_texture_filter_minmax - texture Filter min/max: exposes a new sampler parameter allowing to perform a min or max reduction operation on the values sampled inside a texture filtering footprint.
- GL_NV_shader_atomic_fp16_vector - FP16 global atomics: This extension provides a set of new atomic operations operating on 2 and 4 components vectors of 16b floating point values for images, bindless pointers to global memory and storage buffers.
