GLSL Hacker / PhysX 3 plugin WIP - PVD, PhysX Visual Debugger

« on: Today at 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.

(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.

« on: May 09, 2013, 04:27:45 PM »

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.

3D-Tech News Around The Web / Perceptual computing competition from Intel: $100k+ grand-prize

« on: May 09, 2013, 09:35:29 AM »

Starting May 6th and running for six weeks, Intel wants to inspire developers to forge new ground by integrating voice control, gesture control, facial recognition, and augmented reality with apps and games on PCs in the second phase of its Perceptual Computing Challenge. With a grand-prize of $100,000 USD and thousands of dollars in prizing available in 4 different categories, Intel is looking for the most unique, innovative, and bar-raising uses of Perceptual Computing possible.

Developers have six weeks to submit ideas for games, productivity tools, user interfaces, or generally innovative uses of perceptual computing. If their idea is outstanding it will be selected by the panel of judges to progress into round two, where they’ll receive an interactive gesture camera in order to turn their idea into reality.

3D-Tech News Around The Web / libigl - A C++ Geometry Processing Library

« on: May 06, 2013, 11:26:32 AM »

libigl is a simple c++ geometry processing library that has a wide functionality including construction of sparse discrete differential geometry operators and finite-elements matrices such as the contangent Laplacian and diagonalized mass matrix, simple facet and edge-based topology data structures, mesh-viewing utilities for opengl and glsl, and many core functions for matrix manipulation which make Eigen feel a lot more like MATLAB.
