3D-Tech News Around The Web / GPU-Z test builds for OpenCL support
« on: February 15, 2011, 08:16:15 PM »
Wizzard is improving OpenCL support for GPU-Z
If OpenCL on GPU is not detected with your rig, post a screenshot of GPUCapsviewer in this TPU thread

TessMark fails to launch if you forget to reboot after driver installation  :-[

OpenGL tessellation tweaking is not yet implemented (at least for Cedar).

3DMark11 - increased from 433 to 450 points.
I cannot recommend this benchmark for low-end rigs, a session takes ages.

NVIDIA Alien vs. Triangles SE
Framerate doubles with smooth skin and triples with spiky skin, when 2x factor selected.
That's excellent for a tiny Cedar GPU, i mean you can actually play some DX11 games now  8)

3D-Tech News Around The Web / LuxRender 0.8 RC1
« on: February 15, 2011, 06:30:35 PM »
LuxRender runs on all versions of Windows since Windows 2000, including XP, Vista and Windows 7, both 32 bit and 64 bit.

Unbiased rendering is very processor intensive, therefore fast processors with multiple cores will work best. However, the program will run on any modern processor.

3D-Tech News Around The Web / Unity Custom Particle System Demo

Unity Custom Particle System Demo

We have been working on a customizable, artist-friendly way of specifying particle velocities for particle systems in Unity. The built-in particle system animator only allows for a very limited range of motions, and it would be really hard to make the particles flow around obstacles or create vortices.

But before we dive into the details of our custom particle editor, why don’t you have a look at the result in the demo below? (We also demonstrate a Unity implementation of the shimmer shader effect from the previous post as well as a shader which creates foggy mirrors)

3D-Tech News Around The Web / Humus' 1K-Mandelbrot
« on: February 14, 2011, 05:03:02 PM »
This demo is a 1K demo, that is, the final binary is no more than 1024 bytes in size. The main secrets to creating such a tiny executable is first to throw out the C runtime, and secondly to link with a compressing linker, such as Crinkler.

FYI: "Microsoft security essentials" is very slow on checking crinkler packed files  :P

3D-Tech News Around The Web / Unity 3D 3.2 is Available
« on: February 13, 2011, 03:36:20 PM »
We are so happy to announce that Unity 3.2 is now live and available to download!

Here is a rundown of the major new features and improvements:
# Image Effects: New Depth of Field with fantastic bokeh, improved bloom and several other image effect tweaks and fixes.
# New Water: All new Water prefab in standard assets that includes waves, automatically generated foam on shorelines and more. It even has a full fledged editor – make those oceans come alive.
# Graphics: Major performance improvements in OpenGL ES 2.0 (iOS/Android).
# Shaders: Added optimized/simplified versions of some shaders under “Mobile” category (VertexLit, Bumped Specular, Skybox). They work on other platforms as well, but mobiles will see biggest gains. Bumped Specular is 5.3x faster on iPhones.
# Shaders: Added several Unlit shaders that just display a texture with no lighting. They are the fastest textured shaders.
# Debugger: Attaching the script debugger to (and detaching from) Unity and debugging-enabled players is now possible.
# Profiler: you can profile standalone player builds from the Editor. This includes iOS and Android builds!

For a full list of all of the updates fixes and improvements, head over to the release notes.

3D-Tech News Around The Web / GLIntercept 1.0 beta
« on: February 10, 2011, 06:57:12 PM »
A beta release of GLIntercept 1.0 is now out at:

A few things to note:
- This is more a maintainable release - new function entry points and some minor bug fixes.
- OpenGL3.0 + pure core profiles do not work correctly (will be fixed)
- New resource types like array textures, geometry shaders etc are not currently logged.
- No x64 bit program support.
- Nvidia's multi threadded driver seems to issue an internal wglGetPixelFormat call on the first glGetError() after SwapBuffers. This internal call occurs on a different thread that does not have the main OpenGL conext - so it results in the OpenGL error:
"GL ERROR - Function wglGetPixelFormat generated error GL_INVALID_OPERATION"
for the first 23 times swap buffers is called.
To fix, disable the multi-threadded driver from the Nvidia control panel:
"Manage 3D settings -> Threadded Optimization -> Off"
or you can enable the GLIntercept option "ThreadChecking = True" which will report the extra wglGetPixelFormat call occuring on a different thread. (as well as some other wglDescribePixelFormat calls made by the driver)

I will probably do a few more betas before the final, so hopefully a few of the above features/fixes will make it in.

As there are so many other OpenGL loggers on Windows these days I will probably not do too many more updates. (and OpenGL is a hard API to write a debugger for)

Let me know of any bugs you encounter.

Today, we’re launching Flash Player 10.2 for Windows, Mac, and Linux. We’re especially excited that this release introduces Stage Video, a full hardware accelerated video pipeline for best-in-class, beautiful video across platforms and browsers. Additionally, this version of Flash Player offers all the new capabilities previewed in our beta release, like custom native mouse cursors, multiple monitor full-screen support, Internet Explorer 9 hardware accelerated rendering support, and enhanced sub-pixel rendering for superior text readability.

Panasonic was in a hurry and released an OEM driver compiled January 2010 (!) today  ::)

The Technology Behind the DirectX 11 Unreal Engine Samaritan Demo (Presented by NVIDIA)

This talk will focus on next generation graphics effects developed for Epic's GDC 2011 Samaritan demo. Epic engineers, in collaboration with NVIDIA, extended the engine to support Direct3D 11 and add displacement mapping. This talk will explain the bumps encountered and overcome along the way, along with extensive details on how displacement mapping was exploited in the demo. The talk will also explain in detail the many other new graphical features highlighted in the demo: screen space surface scattering for skin rendering, deferred rendering with MSAA, short hair rendering, blurry reflections based on ray-casting an approximate scene, and high quality depth of field featuring custom bokeh.

Realistic and Interactive Clothing in Epic Games Samaritan Demo Using NVIDIA APEX (Presented by NVIDIA)

In this session, we will show how artists can generate realistic and interactive clothing using the APEX Clothing module. Step by step, we will demonstrate the full authoring pipeline, from DCC tools to final integration into a game engine (in this case Unreal Engine 3) and present how real clothing can provide a totally new cinematic game experience. This session introduces the full NVIDIA APEX suite of artist friendly tools and runtime libraries (Clothing, Destruction, Particles and Turbulence) which significantly speed up creation and inclusion of scalable, dynamic content without large engineering effort into any game engine.

3D-Tech News Around The Web / Blender Ocean Simulator
« on: February 08, 2011, 05:27:56 PM »
Ocean Sim is a community sponsored development project. A first build was already available for contributors, and now the general public has access to it as well!

    Yes folks, we’ve reached a milestone! We’ve ironed out most of the issues and bugs in the OceanSim Build of Blender 2.56, and are ready to have the wider Blender community have a look at it!

    Based on the budget we generated from donations, we’ve reached a feature-complete version of the OceanSim branch. Any further work from Phase1/2 will be bugfixing.

    We currently have builds available for Win32/64, Linux32/64, and OSX10.5+ available on our Builds Download page here. There is also a code patch in case you’d like to build your own. New bugs or issues can be reported on our Bug Tracker page.

Check out the features list and download a build!
