3D-Tech News Around The Web / Khronos' President talks OpenCL, DX Compute Shader, and more

« on: August 05, 2009, 07:04:49 PM »

We recently had the opportunity to speak with Neil Trevett, who fills positions as both the Khronos Group's President and Nvidia's VP of Embedded Content. Consumers might not hear the Khronos name too often, but the organization is responsible for setting and updating a number of key standards: among them OpenGL, OpenGL ES, and most recently, OpenCL.

3D-Tech News Around The Web / High-Performance Graphics 2009 - a closer look

« on: August 04, 2009, 06:47:01 PM »

When discussing things to do and see at SIGGRAPH, it is important to note the co-located conferences.  This year, SIGGRAPH is co-located with the Eurographics Symposium on Sketch-Based Interfaces and Modeling (SBIM), the Symposium on Computer Animation (SCA), Non-Photorealistic Animation and Rendering (NPAR), and High-Performance Graphics (HPG).  SCA has had good animation papers over the years, and is of interest to many game graphics programmers. NPAR is also a good conference for anyone interested in stylized rendering.  In this post I will focus on HPG, which is a new conference formed out of the merger of the venerable Graphics Hardware conference, and the newcomer Symposium on Interactive Ray Tracing.

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.
