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?

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

 init_scene:

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")



update_scene:

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


That's all.

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;

#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.

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:

Adreno GPU SDK - Vulkan Early Access Request

Qualcomm Technologies, Inc. supports the release of Vulkan from Khronos with the Snapdragon™ 820 and embedded Adreno™ 530 GPU. We will be launching the Adreno SDK v5.0 and Snapdragon Profiler v1.5 with Vulkan support on March 14, 2016. We are extending pre-release access to developers and partners who have access to the Snapdragon 820 mobile development platform and are working on specific projects that would benefit from these new tools.

« on: February 17, 2016, 04:24:38 AM »
The PowerVR Early Access Program was created in order to allow developers early access to Vulkan. Developers can start writing great applications on our hardware with device images for supported platforms.

PowerVR Graphics SDK v4.1 is due for release mid-March 2016. It will include:
  • A Vulkan backend for the PowerVR Framework abstraction layer (PVRAPI)
  • New examples (source and binaries) to demonstrate key Vulkan features

Porting a Graphics Engine to the Vulkan API

The new Vulkan API from Khronos is the first to be designed to work across all platform types. Vulkan is a very low-level API that gives developers explicit control of *everything*.

 
In this blog we want to share with developers our experience of porting a graphics engine to the Vulkan API. The engine we decided to port to Vulkan has already had support for various other standard APIs such as OpenGL 4.5, OpenGL ES 2.0, OpenGL ES 3.2. Although these APIs are all different, they have some characteristics in common, for example that an application cannot efficiently talk with the driver from multiple threads. Implementing multi-threading in those previous APIs would not improve performance as it would require a lot of context switches which would eat up most of the performance budget. The GL APIs were designed for previous generations of GPU hardware and whilst the capabilities of hardware and technology evolved, the API’s haven’t done so at the same rate. Vulkan therefore comes at just the right time to address most of the issues of the existing APIs. It also provides developers with a lot more control and flexibility over resources and how and when “jobs” are executed in the graphics pipeline. It does however mean that there isn’t the level of support developers might have come to expect in working with Open GL ES but there are Vulkan debug layers available for plug in that can do a sense check and keep you on the right track.

Mali Graphics Debugger V3.4 Released with Vulkan Support

This is a very exciting time for Graphics. Today marked the release of Vulkan, which is the latest graphics API to be developed by the Khronos group. It has been completely redesigned from the ground up with a much greater emphasis on low-level efficiency. Some of the key features include better multi-threading support, reduced CPU workloads and for the first time, desktop and mobile will use the same graphics API. This last feature will make generating content for both mobile and desktop even easier. More information about Vulkan can be found in the community ARM Vulkan: Built for Modern Mobile Systems and on the Khronos Website
 
As it is a completely new API we appreciate there could be a learning curve required. Help is at hand though as the Mali Graphics Debugger now has Vulkan support. This means that you will be able to trace your Vulkan applications and see what function calls are being used in your application and in what order. It will also detect end-of-frame events so that you can see what function calls were involved in making each frame.
