Vulkan maps significantly better to our hardware than OpenGL ES ever has. Whilst there’s a lot of focus on Vulkan improving CPU performance and efficiency, there’s a heck of GPU performance and efficiency wins too – they’re just a bit more subtle!
Talking about console quality graphics on mobile is starting to become a bit of a cliché, but I’m going to use it anyway! As mobile GPUs get better and more efficient, Vulkan is a big step on the road to console quality graphics.

3D-Tech News Around The Web / AMD TressFX 3.0 - Fix hair rendering bug

Fix hair rendering bug

Resurrect the ALU_INDEXING path in TressFXRender.hlsl. It is both slightly faster in my brief testing and also eliminates the hair rendering issue seen on AMD.

Maybe it looks better on AMD GCN GPUs (have none handy), but on NVIDIA it still looks like an old carpet.

3D-Tech News Around The Web / Blender - New Cycles Benchmark
« on: March 02, 2016, 02:04:27 AM »
 New Cycles Benchmark

  Blender Institute prepared six Blender files for testing Cycles rendering with CPU/GPU, using various settings and design styles but based on actual production setups. On the links below you can inspect the spreadsheet with results, and load the .blend file collection.
The goal is to have an overview of systems that are used or tested by developers of Cycles. We aim at updating it regularly, also when new hardware comes in – and especially when render features improve in Cycles.
Most strikingly so-far is that the performance of CPUs is in a similar range as GPUs, especially when compared to costs of hardware. When shots get more complex, CPUs win the performance battle. That confirms our own experience that fast GPU is great for previewing and lighting work, and fast CPU is great for the production rendering. But… who knows what the future brings.
Feel free to post own stats and observations on this blogpost! Maybe other .blend files should be added?

SAMSUNG OEM with "Intel® HD Graphics 515"

EDIT: Samsung Galaxy TabPro S detachable now available

EDIT 2: DELL OEM version available

EDIT 3: Lenovo OEM version available

EDIT 4: alt. DELL OEM version available

Installation on other rigs:

 In INF file replace [Manufacturer] section with that from last driver that worked for you.

Attention Windows insiders: there seems to be a bug in BCDEDIT coming with build 14271.
 If following commands fail, grab a copy of BCDEDIT from your WINDOWS.OLD folder

 STEP 2a)
 disable driver signature - secure boot off

 bcdedit -set load options DISABLE_INTEGRITY_CHECKS
 bcdedit -set test signing ON

 STEP 2b)
 disable driver signature - secure boot on

 bcdedit -set load options DISABLE_INTEGRITY_CHECKS
enable test signing via enhanced start options

 STEP 3)

English forum / How to use webcam texture in a GLSL Shader
« on: February 26, 2016, 06:07:34 PM »
That one is quite easy


copy webcam code from geexlab_code_sample_pack/host_api/webcam/webcam_win32_spout_test.xml ( the other demos didn't work on my rig for some reason)

rename tex01 to webcamtex to avoid confusion

and don't forget (like me in first place) to add

quad = gh_mesh.create_quad(winW, winH)
shadertoy_prog = gh_node.getid("shadertoy_prog")


gh_texture.bind(webcamtex, 0)
gh_utils.webcam_update_texture(webcam1, webcamtex)
gh_gpu_program.uniform1i(shadertoy_prog, "iChannel0", 0)

That's all.

Package contains named TDF demos and whatever had japanese comments at GLSLSandbox


mouse support injected in "Dragon" to control camera (originally triggered by ZOOM flag)
, will do that more often in future if it makes sense
NB: NVIDIA doesn't render dragon's skin

GLSLSandbox shaders are converted to Shadertoy format to avoid MOON3D and use GFX03.LUA instead (better mouse and texture support)
this requires following header

Code: [Select]
uniform vec3      iResolution; 
uniform float     iGlobalTime;
uniform vec4      iMouse;
uniform sampler2D iChannel0;
vec2 resolution = iResolution.xy;
vec2 mouse = min(iMouse.xy / iResolution.xy, vec2(1));
#define time         iGlobalTime
#define renderbuffer iChannel0
#define backbuffer   iChannel0
#define bb           iChannel0
vec2 surfacePosition = (2.0 * gl_FragCoord.xy - resolution.xy)/resolution.xy;
vec2 surfaceSize = gl_FragCoord.xy / resolution.xy;

F1* 2015  is the latest FORMULA ONE* game produced by Codemasters, based on a unique iteration of their proprietary EGO engine. The game was created almost entirely from scratch with the new game engine dramatically improving both the visual quality and AI abilities. The F1 2015 engine is Codemasters’ first to target the eighth generation of consoles (PS4* and Xbox One*) and PCs.

The new engine architecture was designed to run on the multiple cores found in the consoles with the intention that it would scale to work equally well on the PC. A patch in November 2015 that added an updated audio system, and together with higher quality settings for the CPU-driven particle system, makes full use of high-end gaming PCs.

This article details most of the work done for the patch.

3D-Tech News Around The Web / Notepad++ 6.9 released
« on: February 22, 2016, 04:53:11 PM »

v6.9 contains a new feature Folder as Workspace which is one of most wanted features.
Folder as Workspace opens your folder(s) in a panel so you can browse folder(s) and open any file in Notepad++. Every changement in the folder(s) from outside will be synchronized in the panel. Usage: Simply drop 1 (or more) folder(s) in Notepad++.

For the security reason, Notepad++ binaries is signed from the v6.9. I make it a point to thank DigiCert for their code sign certificate donation.
More enhancements and bug-fixes are done in this release. Please check Notepad++ v6.9 download page for more information:
