"I think graphics matter a lot," Yerli asserts. "It depends on the type of game. If graphics and technology, AI and physics provide you a better experience but a challenge, then ultimately it does matter. You can get an experience out of Crysis 2 you just don't get anywhere else."

3D-Tech News Around The Web / Jitter - Fully managed physic engine

Hi, this are some screenshots of a physic engine for .NET Iam working at for some month now - called 'Jitter'. It's my first attempt to make a physic engine (JigLibX was my first engine, but it's just a port of a c++ engine).

It uses accumulated impulses for the solver and mpr (xenocollide) for collision detection. It currently uses some code of Bullet for raycasting - I didn't had the time to implement that myself.

It's entirely written in C# and does not depend on the XNA framework - using it's own math classes. (The demo uses XNA). It's highly optimized for C# and pretty lightweight.

At the moment it does all the basic things a physic engine should do (Octree based trianglemesh collisions, constraints, stable simulation..). I hope to implement vehicle and cloth-simulation later.

You can download a compiled demo version here: http://jitter-physics.com

NVIDIA® OptiX™ ray tracing engine beta download

Changes from version 2.0.0 B3
  Additional documentation for interop added to the OptiX reference manual.
  Programming guide has been updated.
  Slight modifications of the OptiX headers to remove any dependence on the CUDA run time if
using these headers.  You should not need to update your code.
  Added simpleGLTexInterop sample to demonstrate how to use the new texture interop
functionality of OptiX.
  Mouse interactions with sutil’s Mouse class will now ignore interactions that result is setting the
camera with NaNs or Infs.
  Added support for non-affine transforms in Transform nodes.
  Some fixes for the new GL interop functions.
  Fixed problem with memory fragment errors when using many acceleration structures.
  OptiX shared libraries now depend on 3.0 release version of the CUDA cudart library.

Known limitations with version 2.0.0 Beta 4:
  OptiX will choose to ignore older devices if a SM 2.0 device (i.e. “Fermi” class) is present in the
sytem.
  The Lbvh acceleration structure builder is known to fail in single GPU Linux systems and while
using multiple GPUs in all OSes.  Please use a different builder for the time being.
  There currently is a concurrent texture limit of 128 textures. This limit will be either increased, or
entirely removed in the future, although large numbers of textures will always be likely to
negatively impact performance.  An error is returned by OptiX if this limit is exceeded.
  Texture arrays and mip maps are not yet implemented.
  Applications that use RT_BUFFER_INPUT_OUTPUT or RT_BUFFER_OUTPUT buffers on
multiGPU contexts must take care to ensure that the stride of memory accesses to that buffer is
compatible with the PCIE bus payload size.  Using a buffer of type RT_FORMAT_FLOAT3, for
example, will cause a massive slowdown; use RT_FORMAT_FLOAT4 instead.
  Linux only: due to a bug in GLUT on many Linux distributions, the SDK samples will not restore
the original window size correctly after returning from full-screen mode.  A newer version of
freeglut may avoid this limitation.
  Performance on Windows Vista and Win 7 should be expected to be somewhat slower than XP
due to the inherent nature of these operating systems

There's no denying that NVIDIA needs to bring Fermi down to the mid-to-high-end space, and early rumours suggest it'll happen in less than two months.

Mozilla has advanced fast in the browser segment and is found on almost every third computer, depending on source and survey. Never have so many expected so much from the company, but it has remained true to its focus on features and performance, where new competition from Google has raised the bar. Mozilla is said to have several important things on its agenda for coming versions of Firefox and this includes GPU acceleration and separate processes for extensions.

Introducing a system for separate processes is closest at hand where you for example will be able to run Adobe Flash as its own process and where extensions with stability problems will not affect the browser as a whole. Something Google Chrome has been offering for some time. This is a feature that is expected to be introduced by the end of Q2, I.e. June.

GPU acceleration is another hot topic and here Mozilla hopes to offer Direct2D support in an update for Gecko 1.9.3, slated for October launch. Unfortunately this release doesn't include the Direct2D acceleration, but will be added later on, but hopefully not that much later.

The next step is Direct3D support, but this is not something it has even put up guidelines for.

3D-Tech News Around The Web / TechPowerUp GPU-Z v0.4.1

GPU-Z is a lightweight utility designed to give you all information about your video card and GPU.

Please note: Some versions of McAfee Antivirus report a "Generic!Artemis" infection. This is a McAfee specific false positive, GPU-Z is not infected with any virus/trojan.
Revision History
0.4.1

    * Fixed an issue on all NVIDIA cards that would sometimes cause them to lose fan control when GPU-Z is running. Please don't run pre-0.4.1 and 0.4.1 at the same time, this might result in incorrect readings in the 0.4.1 window.
    * Fixed system crash on MSI HD 5830 TwinFrozr II
    * Validation upload now uses Unicode for entered name
    * Reverted memory bandwidth calculation introduced in last version. It introduces too much confusion, we will go with what all companies use in their marketing material, even though we believe it is not correct. Using power of 10 again now, 1 GB/s = 1,000,000,000 Bytes per Second.

Geist Software Labs has released the first version of OpenCL Studio for beta testing. OpenCL Studio combines OpenCL and OpenGL into a single integrated development environment that allows you to visualize OpenCL computation using powerful 3D rendering techniques. The editor hides much of the complexity of the underlying APIs while still providing flexibility via the Lua scripting language. Integrated source code editors and debugging capabilities for OpenCL, GLSL, and Lua, as well as a toolbox of 2D user interface widgets provide a framework for a wide range of parallel programming solutions.

Gamers demand performance and realism. They are tired of the same old video games that look the same and play the same, but have different names. We usually blame this on the developers but we should have been blaming it on the video card manufacturers. The problem wasn’t the lack of imagination on the developers’ part, it was due to the lack of technology available to them via the GPU.

OpenGL 3.2 and GLSL 1.5 is available but there is a lack of simple and complex example programs.
On this webpage, we do want to fill this gap by providing example programs using OpenGL 3.2 and GLSL 1.5 with GLEW and GLUS.
Please note, that all example programs do not use any deprecated OpenGL functions.

Our first short tutorial  is ready, it provides a glimpse of our new UI and it shows how easy it is to use NeutronE. Applying tessellation is very simple, it takes just a few mouse clicks to turn a low poly mesh into a detailed smooth mesh and the best part is that all this happens real-time without any need for mesh modification!

After years of development NeutronE is finally ready for it's first tech-demo! It demonstrates all key features provided by powerful NeutronE rendering pipeline including DirectX 11 tessellation, compute shader, real-time effects etc. Please note that we didn't have time to involve professional artist(s) in the development of the demo so the emphasis is on the technology not the art.

Works also fine with SM4 GPU  8)

3D-Tech News Around The Web / S2Engine 2009 and NVIDIA PhysX

S2ENGINE 2009 and NVIDIA PhysX.

During the last month we have worked night and day on Physics subsystem. We have choosen to implement NVIDIA PhysX library 'cause we think it is the best library the market could offer. Now S2Engine can perform rigid bodies, joints, ragdolls and vehicles.
Many other features are planned for the future, taking advantage of the great possibilities NVIDIA PhysX offer.

A HD YouTube videoclip shows the work in progress...

Crytek has claimed that Crysis 2 contains the best graphics in the history of video games.
Yes, it's a bold statement - especially as the studio has admitted some teething problems getting its power-hungry CRYEngine 3 to work on consoles.
But it's adamant that it has something pretty special on its hands - and even prettier than the stunning original Crysis on PC.
