Graphics card manufacturer XFX has accidentally confirmed on their website that the upcoming AMD Radeon R9 390X is, in fact, a rebranded version of the R9 290X, which launched towards the end of 2013.

On their product page for the XFX Radeon R9 290X Double Dissipation Edition, towards the bottom of the page the company has posted a picture of a box that clearly shows R9 390X branding. The card itself comes with two large fans atop a cooler that includes seven heat pipes, plus the usual selection of display outputs: two DVI, one HDMI, and one DisplayPort.


Nvidia and TSMC allegedly tape out next-gen 14nm Pascal GPU

According to sources on the Beyond3D and 3DCenter forums Nvidia's next-gen Pascal GPU has been taped out. Thus the first of the Pascal architecture chips, known as the GP100, has successfully been prototyped using the TSMC 16nm FinFET Plus process. This is a significant milestone and now engineers will be able to test and tweak the design to ready it for market rollout.

Thanks for your work Stefan!

I know where to find the demos for the next update of MadShaders  ;)

Oculus Rift Confirms "Pause" in OS X, Linux Development, Some Devs are Mad:

Our development for OS X and Linux has been paused in order to focus on delivering a high quality consumer-level VR experience at launch across hardware, software, and content on Windows. We want to get back to development for OS X and Linux but we don’t have a timeline.


A common practice in computer graphics is to pack and compress vertex attributes. It reduces the memory footprint, time to transfer data across the bus from the CPU to the GPU, and GPU memory bandwidth at the cost of extra instructions in the vertex shader. Another benefit may be that there are more attributes than the maximum number of vertex attributes supported.


Intel v4206 fixes some MadShaders 0.4.x rendering glitches (see HERE):

- Bokeh blur: OK

- Mobius balls: OK

3D-Tech News Around The Web / An Introduction to OpenCL C++
« on: May 13, 2015, 04:15:31 PM »
An introduction to the latest provisional OpenCL 2.1 specification with a kernel language based on C++:

Other tutorials and articles about OpenCL can be found HERE.

Synthclipse is a GLSL shader prototyping tool. It makes possible to fast develop all kinds of shaders: Fragment (FS), Vertex (VS), Geometry (GS), Tessellation (TS) and Compute (CS). Shader development can be done using, compatible with Fragmentarium and Shadertoy (but limited to FS and VS), Fragx shaders or by using fully featured JavaScript JSX scripts. The JSX API is consistent with WebGL but in fact exposes complete OpenGL 4+ API.

Synthclipse is based on Eclipse IDE and depends on Eclipse CDT (C/C++ Development Tooling). It pretends that GLSL is just plain C++ code.


SYCL (pronounced ‘sickle’) is a royalty-free, cross-platform abstraction layer that builds on the underlying concepts, portability and efficiency of OpenCL that enables code for heterogeneous processors to be written in a “single-source” style using completely standard C++.   SYCL enables single source development where C++ template functions can contain both host and device code to construct complex algorithms that use OpenCL acceleration, and then re-use them throughout their source code on different types of data.


3D-Tech News Around The Web / ClanLib 4.0 released
« on: May 11, 2015, 08:19:42 PM »
ClanLib is a cross platform C++ toolkit library with a primary focus on game creation. The library is Open Source and free for commercial use.

The ClanLib C++ Game SDK has been updated. Key updates since previous release include a path drawing module using CPU/GLSL to render anti-aliased SVG style primitives (including lines). Now fully supports Windows, Mac OS X and Linux. All source has a very liberal zlib style license

English forum / GLSL Hacker 0.8.4
« on: May 11, 2015, 07:31:30 PM »
This is the thread for feedback and bug reports of GLSL Hacker 0.8.4.x.

GLSL Hacker 0.8.4 story:

kiUi is a lightweight auto-layout Ui library, abstracted out from any rendering or input code.

Every single element in kiUi auto-layouts ! You have nothing to do. No position to set, no size to determine.

kiUi was conceived so that each element can be styled in a way very similar to CSS, through Style Sheets You can switch between Styles Sheets on the fly.

kiUi comes with a light renderer / input system based on NanoVG and GLFW to quickly bootstrap a prototype application in a few lines of code.


- Intel v4170 + Intel HD Graphics 4600 + Windows 8.1 + GLSL Hacker
- demo: host_api/gl-430-arb-compute-shader-particles-ssbo/grid_deformer_v2.xml (Code sample pack )

The demo works fine (245 FPS).

English forum / Intel Graphics Drivers and GPUs
« on: May 07, 2015, 02:39:27 PM »
I start this thread to post screenshots of GLSL Hacker based demos and applications that have issues with Intel graphics drivers.
I also post screenshots of demos that work fine with Intel GPUs!

The last Intel v4170 has some issues (that should be fixed in an upcoming driver version) with MadShaders 0.4.0 (correct screenshots can be found in this page). I tested with an update of  MadShaders (v0.4.1) without change:

- Mobius Balls: the central big sphere is nor rendered

- Bokeh blur: no comment!

MERCI for the bug-report!

Indeed the OBJ loader was broken. I fixed it and the new version will be available with the new GLSL Hacker
