Epic Games, Inc. has released the August 2011 UDK Beta, the latest version of the Unreal Development Kit (UDK), the free edition of Unreal Engine 3 that provides access to the award-winning toolset used in blockbuster video games, 3D visualizations, digital films and more.

Also check out Inside UDK: Fall 2011 trailer and showcase Desert Zombie Last Stand TPS for iOS

So yeah, a bunch of us were at SIGGRAPH 2011 in lovely Vancouver, doing talks, meeting people and going to super interesting sessions. Me & ReJ did a long technical session about optimizing graphics for mobile platforms. GPU architectures, shader optimization details, case studies from actual Unity games and so on.

Here it is: Fast Mobile Shaders (17MB pdf).

Note: the developer of the unanounced title in this document is "Luma Arcade", who also have a lot of nice CG videos here

3D-Tech News Around The Web / [Android] OpenGL ES 2.0 Demo
« on: August 21, 2011, 12:59:54 PM »

IMPORTANT: Since version 1.2, this app finally works on Samsung and Motorola devices. If you are a developer please take a look below to the comment for developers just in case the information could be in handy for you as well. THANKS EVERYONE for the reports.

---------------------------

Demo that shows some cool effects that can be achieved thanks to the programmable OpenGL ES 2.0 GPU pipeline, such as normal mapped specular animated lighting, real time refractions and image postprocess.

If you like the effects and would like to play a game that uses them, please try the game "AQUA SLASH GL DEMO" for free.

To move the light source, touch the screen with one finger to the desired position.

To change the background image, while touching the screen with one finger (therefore moving the light) touch with another one on the left side of the screen.

To change the postprocess effect, do the same but touch with the second finger on the right side of the screen instead of the left.

This demo requires Android 2.2 or higher.

INFO FOR DEVELOPERS: For some reason, samsung and motorola opengl driver does not allow the creation of FrameBufferObjects with color attachments of dimensions non power of 2. All the opengl calls do not generate any error and the FrameBufferObject status is ok, but then nothing gets written to the offscreen buffer if width and/or heigth is not power of 2. On HTC, LG, Toshiba and Dell devices this works well and any dimension can be used.

Since this app uses offscreen rendering for the postprocess effects, this is why it did not work with samsung and motorola devices before version 1.2.

3D-Tech News Around The Web / [Android] N-Body Simulator

Watch and interact with a real n-body simulation on your phone!

N-body particle simulator where the behaviour of the system is driven only by each particle's gravity. It is turning more into a physics playground lately though, with the addition of accelcerometer support, elastic collisions and more.
The app has been completely redesigned. Now there is a simulation box from which the particles can't escape. The system is now much more interactive and it performs way better than the previous version. A mid-range device shouldn't have problems with about 70 particles (without trails and collisions).

Features:
-Real n-body simulation, pure gravitational interactions between particles.
-Zoom and pan in big simulation area mode.
-Create walls particles can't trespass. Watch them bounce off.
-Allow or not physically realistic elastic collisions or mergers between particles.
-Set particle and background colors.
-Set gravity strength and particle mass.
-Accelerometer support.
-Shoot particles or create repulsive forces using touchscreen.
-Also create repulsive particles.
-Possibility to choose simulation area size, leaving it just the size of your device's screen or making it large.
-Enable or disable the central black hole which exerts a neat attractive force towards the center.
-Enable or disable particle trails (disable to improve performance).
-Modify simulation velocity in real time.

Check out the new LIVE WALLPAPER version, it's free and it's on the market now! It will remain with the old version of the app by now.

Contact me if you have suggestions for new features or found any bugs.

Note: set simulation area = screen to avoid emptyness on the screen

Highlights of the AMD Catalyst™ 11.8 Windows release include:

New Features

    AMD Overdrive has been enhanced to include both CPU and GPU over-clocking controls within the AMD Vision Control Center
    CPU over-clocking is only supported on AMD Black edition CPUs

Performance Highlights

    Improves performance up to 10% in Crysis 2 DirectX 11 version for both non-Anti-Aliasing, and application enabled Anti-Aliasing cases on the AMD Radeon™ HD 6000 and AMD Radeon™ HD 5000 Series
    Improves performance up to 8% in Fear 3 DirectX 11 version with application enabled Anti-Aliasing on the
    AMD Radeon™ HD 6000 and AMD Radeon™ HD 5000 Series
    Improves performance up to 30% when AMD’s Morphological Anti-Aliasing (MLAA) is enabled through the

Efficient multi-fragment rendering using d-buffer - an OpenGL 4.2 use case

Drawing effects that need to store multiple data elements per-pixel is not an easy task, when you consider an architecture as rigid as highly parallel GPU subsystem. It is even more so, when you want to put irregular number of data elements (e.g. fragments) per-pixel. Current methods often suffer from the low performance pitfalls of non-regular memory references. See how d-buffer storage scheme can help composing your multiple, irregular in terms of per-pixel count fragments into hardware friendly regular data structure. All with the help of GL_ARB_shader_image_load_store, GL_ARB_shader_atomic_counters or simply core OpenGL 4.2.


Doesn't run with my ATI Cedar  :P

Evoke 2011 is over

Thanks a lot to everyone (the other organizers, our partners, live acts, visitors and those who contribute in the compos) for making this one of the best Evoke editions in history: 2011 will be a great year to remember!

Downloads via Pouet

"Recycle 4000" looks nice from the screenshot, but it doesn't run on ATI Mobility as mentioned at Pouet forum

Note: your antivirus software probably complains about crinkler packed demos, MSE takes ages to check them  :P



P.S.
"Bünzli 2011" is scheduled 26/27/28 August 2011 in Olten/Switzerland

3D-Tech News Around The Web / NVIDIA GPUDirect 2.0
« on: August 09, 2011, 05:50:50 PM »

First released in June 2010, GPUDirect v1.0 is already supported by InfiniBand solutions such as those available from Mellanox and QLogic, and other vendors are adding support for GPUDirect in their hardware and software products now.

Applications using GPUDirect v1.0 with network and storage devices can realize up to 30% performance improvement in data transfer times on NVIDIA Tesla™ and Quadro™ products. GPUDirect enables this significant speed-up by allowing network adapters, solid-state drives (SSDs) and other devices to directly access CUDA memory, eliminating unnecessary system memory copies and CPU overhead.

GPUDirect v2.0 adds support for peer-to-peer (P2P) communication between GPUs over PCIe in the same system, and lays the foundation for P2P communication between GPUs and other devices in a future release.

For more information, see the GPUDirect Technology Overview presentation.
