3D-Tech News Around The Web / AMD Introductory Tutorial to OpenCL

« on: August 04, 2009, 05:17:43 PM »

AMD just published its public OpenCL Beta for the CPU, soon to be followed with support for AMD’s latest GPUs. OpenCL is a young technology, and, while a specification has been published (www.khronos.org/registry/opencl/), there are currently few documents that provide a basic introduction with examples. This article helps make OpenCL easier to understand and implement.

3D-Tech News Around The Web / GPU Address Space Mapping

« on: August 03, 2009, 04:54:41 PM »

This post addresses some of the issues with texture and 2D/3D array address mappings when mixing compute and fixed function as well as dealing with cache lines and the higher granularity of global memory access of GPUs.

For those developers moving on to compute (CUDA, OpenCL, DX11 CS4/CS5), this is going to be an important thing to have a full understanding of!

3D-Tech News Around The Web / NVIDIA ForceWare 190.56 OpenGL 3.2 Beta Drivers available

« on: August 03, 2009, 04:28:00 PM »

This driver supports all of OpenGL 3.2 and GLSL 1.50, except for the following:

    * Geometry shaders as part of the core. You can use the ARB_geometry_shader extension instead
    * glXCreateContextAttribsARB() does not yet support the GLX_CONTEXT_PROFILE_MASK_ARB attribute value. In order to create a Core profile context, call glXCreateContextAttribsARB(), request OpenGL 3.2 as the version, and leave the GLX_CONTEXT_PROFILE_MASK_ARB attribute out. In order to create an OpenGL 3.2 Compatibility profile context, call the "old" glXCreateContext() entrypoint. Note: wglCreateContextAttribsARB() does support WGL_CONTEXT_PROFILE_MASK_ARB.

This driver exposes the following new extensions:

For OpenGL 2.1 capable hardware:

    * ARB_fragment_coord_conventions
    * ARB_provoking_vertex
    * ARB_vertex_array_bgra
    * ARB_depth_clamp

For OpenGL 3 capable hardware:

    * WGL_ARB_create_context (updated to create profiles)
    * GLX_ARB_create_context (updated to create profiles)
    * GL_EXT_separate_shader_objects
    * GL_NV_parameter_buffer_object2
    * GL_NV_copy_image.txt

3D-Tech News Around The Web / Fluid Simulation for Video Games (part 2)

« on: August 02, 2009, 05:04:51 PM »

Simulating fluid motion entails converting continuous equations into simpler discrete equations and using numerical techniques to solve the discretized equations. Spatial discretizations include grid-based and mesh-free methods. Simulations employ techniques for interpolating values between nodes, approximating spatial derivatives and evolving the simulation forward in time, meanwhile satisfying boundary conditions. Fluid simulations also provide the means to provide forces acting on bodies embedded in the fluid, which a separate rigid body simulator can apply.

3D-Tech News Around The Web / Real-Time Deformation and Fracture in a Game Environment

« on: July 30, 2009, 03:02:43 PM »

This paper describes a simulation system that has been developed to model the deformation and fracture of solid objects in a real-time gaming context. Based around a corotational tetrahedral finite element method, this system has been constructed from components published in the graphics and computational physics literatures. The goal of this paper is to describe how these components can be combined to produce an engine that is robust to unpredictable user interactions, fast enough to model reasonable scenarios at real-time speeds, suitable for use in the design of a game level, and with appropriate controls allowing content creators to match artistic direction. Details concerning parallel implementation, solver design, rendering method, and other aspects of the simulation are elucidated with the intent of providing a guide to others wishing to implement similar systems. Examples from in-game scenes captured on the Xbox 360, PS3, and PC platforms are included.

3D-Tech News Around The Web / INTEL Real-time Ray Tracing: 3D Water and 3D Display

« on: July 28, 2009, 04:55:59 PM »

With the power of upcoming many-core architectures Intel is developing, real-time ray tracing (using the physics of light to realistically render an interactive 3D scene) comes closer and closer to the desktop. At Research@Intel Day 2009, Intel researchers showcased the latest innovations from our Real-time Ray Tracing project, including more realistic 3D water and the ability to render more than 500 animated characters at once, and showed a version rendering multiple camera views on a stereoscopic display, in which viewers can see the 3D depth of the scene without the need for special glasses. See video from Research@Intel Day 2009 for more info.

3D-Tech News Around The Web / Pyrit - attacking WPA(2)-PSK via CUDA, Stream and OpenCL

« on: July 27, 2009, 05:24:29 PM »

Pyrit takes a step ahead in attacking WPA-PSK and WPA2-PSK, the protocols that protect today's public WIFI-airspace.

Pyrit's implementation allows to create massive databases, pre-computing part of the WPA/WPA2-PSK authentication phase in a space-time-tradeoff. The performance gain for real-world-attacks is in the range of three orders of magnitude which urges for re-consideration of the protocol's security. Exploiting the computational power of Many-Core- and other platforms through ATI-Stream, Nvidia CUDA, OpenCL and VIA Padlock, it is currently by far the most powerful attack against one of the world's most used security-protocols.
