GeeXLab - english forum / kx framework for OpenGL and Vulkan demos
« on: June 04, 2016, 06:10:46 PM »
kx is a new Lua framework for GeeXLab that provides useful functions for your OpenGL / Vulkan demos. In this first version, the main functionality is to display statistics (framerate, frame time, GPU load, etc.)

The latest code sample pack contains demos that have been updated with this framework (see the code sample pack changelog for more info).

An empty demo with the kx framework:

Here is an article that explains how to use the gh_font module to load True Type Fonts and display 2D texts:

Do you have something particular in the log file?
What is the version of GeeXLab? The version for OpenGL ES or the new version for OpenGL 2.1 ?

3D-Tech News Around The Web / Quake 2 Realtime GPU Pathtracer
« on: May 31, 2016, 01:18:33 PM »
This is a from-scratch GPU-based pathtracer created specifically for Quake 2. It has several optimisations which are only viable due to the typical characteristics of Quake 2 such as support for parallogram-shaped lightsources, BSP ray traversal, and special handling of sky 'surfaces' (portals). It doesn't officially have a name, but you can call it Raylgun.


3D-Tech News Around The Web / Tor Browser 6.0 released
« on: May 31, 2016, 01:12:18 PM »
The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked.

The Tor Browser lets you use Tor on Windows, Mac OS X, or Linux without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained (portable).

GeeXLab - english forum / Shadertoy demos in Vulkan
« on: May 25, 2016, 05:07:16 PM »
For testing how Vulkan plugin works (especially the GLSL to SPIRV converter tool) with more complex shaders, I ported this shadertoy demo to GeeXLab / Vulkan.

No particular surprise, everything worked as expected.

This demo will be available in the next update of the code sample pack.

According to this comparative table, the upcoming GTX 1070 with its 1920 CUDA cores is faster (ok by a very small margin) than the GTX Titan X that packs 3072 CUDA cores.


Rok Erjavec, Technical Director at Crytek, in an interview with DSOGaming:

Q: DSOGaming: Does CRYENGINE support Vulkan and have you experimented with it? If you had to choose one, would you go with DX12 or Vulkan?

A: Rok Erjavec: The current trajectory of Vulkan provides a path to reach PC users across all the widely used OS platforms, including legacy Windows versions, as well as mobile devices, so if I was shipping a title in 2017 or beyond, Vulkan looks like an appealing choice.

Full interview:

Linux 4.5 contains over 21 million lines of code. Around 4,000 developers and at least 440 different companies contribute to the kernel. There are over 10,800 lines of code added, 5,300 lines of code removed and over 1,875 lines of code modified. Every. Single. Day. That amounts to over 8 changes per second.


FireRays is ray intersection acceleration library provided by AMD which makes the most of AMD hardware and allows for efficient ray queries independently of the generation of underlying AMD hardware.

After the success of the first version, FireRays is moving to another major milestone. We are open sourcing the entire library which allows complete integration and contribution from the entire developer community to bring improvements in the rendering world. In fact FireRays 2.0 brings support for Windows, OSX, Linux, AMD, NV, Intel GPUs and CPUs with many back-ends.


3D-Tech News Around The Web / AMD Compressonator is now Open Source
« on: May 13, 2016, 10:43:31 AM »
Compressonator is a set of tools for compressing textures (ASTC, ATC, ATInN, BCn, ETCn, DXTn and swizzled DXTn formats) and creating mip-map levels.

Compressonator is a set of tools to allow artists and developers to more easily work with compressed assets and easily visualize the quality impact of various compression technologies.  It consists of a GUI application, a command line application and an SDK for easy integration into a developer toolchain.

We are very pleased to be announcing that AMD is open-sourcing one of our most popular tools and SDKs.  Compressonator (previously released as AMD Compress on our Developer Central site ) is now available on GPUOpen.

You will get access to:

- GUI Tool source
- Command line Tool source
- Compress SDK source
- All Common Code used for the SDK, GUI and Command line.


Here is an article that explains how to run a Vulkan demo on particular GPU:
