3D-Tech News Around The Web / Leap Motion for Windows

It's what we've always envisioned for Leap Motion — to break down the barriers between people and technology. Here's a video to show you how close we are. With Leap Motion technology, Windows OS is natural, easy, and fun to use. You'll navigate your desktop, browse the web, flip through photos, and do everything you do everyday in extraordinary ways —all with the wave of a hand or lift of a finger.

English forum / PhysX 3 plugin WIP - PVD, PhysX Visual Debugger
« on: May 23, 2013, 09:44:30 AM »
GLSL Hacker is connected to PVD / PhysX Visual Debugger (via Lua/Python calls). The sad thing is that PVD seems to be only available in DEBUG builds. So PVD functions won't work in GLSL Hacker...

Modern GPU is code and commentary intended to promote new and productive ways of thinking about GPU computing.

This project is a library, an algorithms book, a tutorial, and a best-practices guide. If you are new to CUDA, start here. If you're already familiar with CUDA, are ready for a challenge, and want to learn design patterns for parallel programming, enjoy this series.

English forum / GLSL Hacker command line parameters
« on: May 16, 2013, 05:48:56 AM »
Here are the main command line parameters included in GLSL Hacker:
  • /fullscreen
        forces fullscreen mode.
  • /demofile="filename"
        specifies the absolute path to the demo file.
  • /benchmark_duration_ms=<n>   
        specifies the duration of the demo/benchmark in milliseconds.
  • /benchmark_log_score   
        writes benchmark results in the benchmarl log file (CSV file).
  • /benchmark_display_score_box   
        displays the score box at the end of the benchmark.
  • /disable_opengl_support_check   
        disables the check of the OpenGL version done at the beginning of a demo.
  • /noload_plugin_opencl   
        disables the loading of the OpenCL plugin.
  • /noload_plugin_python27   
        disables the loading of the Python 2.7 plugin.
  • /glinfo 
        writes OpenGL complete information (all OpenGL extensions) in the log file.
  • /vbo_usage=<usage>
        forces vertex buffer usage: GL_STATIC_DRAW, GL_STATIC_READ, GL_DYNAMIC_DRAW, GL_DYNAMIC_READ, GL_STREAM_DRAW, GL_STREAM_READ.
  • /ibo_usage=<usage>
        forces index buffer usage: GL_STATIC_DRAW, GL_STATIC_READ, GL_DYNAMIC_DRAW, GL_DYNAMIC_READ, GL_STREAM_DRAW, GL_STREAM_READ.

Example:
GLSLHacker.exe /demofile="C:/The/Path To/The/Demo.xml" /vbo_usage=GL_STATIC_DRAW /benchmark_duration_ms=5000 /benchmark_display_score_box

(the samples below, for some reason GPU test fails).


Maybe the failure is related to the fact that GPUTest is a 64-bit application? All other benchmarks (FluidMark, FurMark, ...) are 32-bit apps.

Today's CPUs are capable of supporting realtime audio for many popular applications, but some compute-intensive audio applications require hardware acceleration. This article looks at some realtime sound-synthesis applications and shares the authors' experiences implementing them on GPUs (graphics processing units).

3D-Tech News Around The Web / real time ray tracing part 2.

In the last post I gave an overview of my journey through realtime raytracing and how I ended up with a performant technique that worked in a production setting (well, a demo) and was efficient and useful. Now I’m going go into some more technical details about the approaches I tried and ended up using.
