3D-Tech News Around The Web / Deferred Global Illumination using OpenGL 3.2
« on: September 16, 2009, 11:39:36 PM »
I started new GI renderer, using OpenGL 3.2. I create multiple point lights to simulate GI, and use deferred shading to render them. With nv_explicit_multisample, I have real antialiasing (not edge-blur-filter).
Link to demo: (compatible with 190.57 nvidia drivers).

I've also posted explicit_multisample tutorial:

3D-Tech News Around The Web / PlayStation 3 - Physics Effects SDK
« on: September 16, 2009, 05:17:12 AM »
At CEDEC 2009, Sony Computer Entertainment exhibited the Physics Effects SDK. The Physics Effects SDK is a physics simulation engine optimized for the Cell Broadband Engine, which is provided as part of the PlayStation 3 SDK. Because the Physics Effects SDK is optimized for PlayStation 3, it can do physics simulations very fast, even though they are considered to impose a very high computing load. This could expand developers’ scope to include even more complex physical phenomena and mechanisms in games.

3D-Tech News Around The Web / Re: NVIDIA Forceware 190.89 OpenCL available

OpenCL 1.0 Conformant Release (Tools & Utilities) is now mirrored at LV2go

So, given all the hype, what can we expect from OpenCL? Is it really simple? Is it portable? Will it replace other parallel programming models? It's still a little early; we've seen a multicore demonstration of OpenCL from AMD, a limited developer release from NVIDIA, and Apple is planning to release its next generation operating system in September, including OpenCL support. Yet we can prognosticate, given what we know about the language and related technologies.

Bullet 2.75 is available for download now (SVN revision 1754)

Some features:

    * Smoothed Particle Hydrodynamics (SPH) fluids preview, thanks to Rama Hoetzlein for contributing this under the ZLib license! See Bullet/Extras/sph. The SPH fluids will be integrated into Bullet with two-way interaction, similar to cloth/soft body simulation.
    * GPU physics kernels preview, in preparation for Bullet 3.x. Right now mainly CPU version, you can enable CUDA version manually. The OpenCL version is available in a separate branch. See Bullet/Demos/Gpu2/3dDemo
    * 2D physics demo, with 2D and 3D object interaction, see Bullet/Demos/Box2dDemo
    * New constraints: btHinge2Constraint,btUniversalConstraint,btGeneric6DofSpringConstraint, thanks to Roman Ponomarev
    * Use ALT+Left/Middle/Right Mouse button+mouse motion for Maya-style camera navigation
    * Re-enabled split impulse constraint solver option, to avoid adding momentum due to penetration recovery (includes SIMD support)
    * Removed first argument 'localInertiaTensor, from btMultiSphereShape. Update your code by remove the first argument: it calculates its local inertia from its aabb now.
    * Increased performance by disabling motion state synchronization for static/inactive objects.
      Use btDiscreteDynamicsWorld::setSynchronizeAllMotionStates(true); for backwards compatiblity.
    * Improvements in Soft Body simulation: added tetrahedral volumetric demos, allow for per-triangle/per-tetrahedron collision (pass 0 in generateClusters), increased stability for cluster collision, improved performance of bending constraint generation.
    * Added pre-tick callback option, called at the start of each internal simulation substep.
    * Added optimized capsule-capsule collider, useful for ragdolls.
    * many bug fixes

3D-Tech News Around The Web / Nvidia's Ian Buck Talks GPGPU
« on: September 11, 2009, 11:34:19 PM »
I seriously started looking at GPU computing during my PhD research at Stanford. At Stanford, I, along with others in the research community realized that the natural progression of programmable graphics was the evolution of the GPU into a more general purpose processor. We wrote one of the first SIGGRAPH papers on ray tracing with DX9-class GPU hardware to help prove the point. What was so motivating about the work was that this commodity processor, which was available in everyone’s PC, was following a Moore’s law cubed performance growth rate, way faster than the CPU. This begged the question: what could a PC do if it had multiple orders magnitude more computing horsepower than today? A total game-changer for the computational sciences as well as computer vision, AI, data mining, and graphics.

With six months of ATI CatalystTM driver blogs under our belt, we are seeing a growing engagement from the community via this blog site. Please keep up the great comments and suggestions and we will endeavor to answer as many as we can. So, without further ado - let me introduce the ATI Catalyst 9.9 Driver Release!

Game Optimizations: ATI CatalystTM9.9 Driver
With last month’s release of the ATI CatalystTM 9.8 driver, we saw huge game performance increases, given that, this month the driver team focused on other applications and optimizations.

ATI CatalystTM 9.9 Driver has no new features but does have the following resolved issues:

Anti-Aliasing support for Ghostbusters
ATI CrossFireXTM support for Resident Evil 5
Graphics corruption fix for Sims 3
ATI CatalystTM Control Center - Basic mode now responds appropriately after exiting Quick Adjust Video Settings
Edge enhancement and de-noise sliders in ATI Catalyst Control Center no longer lags or appears out of sync with mouse movement
Launching Hotkeys Manager in ATI Catalyst Control Center no longer causes an unhandled exception error
The “Desktop Rotation” page in ATI Catalyst Control Center no longer shows additional information for the second display when the secondary adapter is connected
HDMI is now detected properly as DTV (HDMI) instead of DTV (DVI) when the HDMI display is hotplugged for the first time
ATI Catalyst Control Center no longer displays error message when specific HDMI displays are hot unplugged and hotplugged back
Intermittent failures no longer occur with Cyberlink MediaShow Espresso once a transcoding process has been completed

And last but surely not least, my favorite community: ATI CatalystTM 9.9 driver for Linux!

Support for new Linux operating systems
This release of ATI Catalyst driver for Linux introduces support for the following new operating systems:

• openSUSE 11.1 production support
• SLED and SLES 10 SP3 early look support

3D-Tech News Around The Web / DirectX 11 – What to expect (from ATI)
« on: September 11, 2009, 06:51:01 PM »
Now, if you are a gamer you undoubtedly will be asking me “What games are going to support DirectX 11″? This is always a tightrope to walk for us as we are unable to pre-announce our technology partners titles and the specs around those titles; still, we want to give the consumer confidence that we’ve been assured there will be substantial titles in the market that take full advantage of your ATI Radeon DirectX 11-compliant graphics card. So, as this blog is published, here are the future DirectX 11 games we can talk about:

Dirt2 by Codemasters
BattleForge by EA
S.T.A.L.K.E.R: Call of Pripyat by GSC Game World

With High-Definition (HD) video gone mainstream thanks to digital TV transition in different countries around the world and HD camcorders (such as AVCHD) becoming more affordable, there is now more demand for additional processing capability to edit and convert HD content. In order to edit and convert with relatively reasonable speed, end-users needed a PC with high-end CPU configuration…that is, until recently.

Consumers are now able to convert their video files leveraging their GPU hardware inside their PC. Simply put, with graphics cards and applications specially constructed to take advantage of the GPU, you are now able to tap into the massive amounts of parallel compute power, you may not even have been aware your PC had. Cool, huh?
