Spiral Blog: Paper World Texture Set.
An unusual texture set that allows you to create scenes that look like they’ve been mocked up from arts and crafts materials.

New simple, yet complete, sample of code to draw two triangles using OpenGL 3.3 and GLSL 1.5. As far as I know the sample does not use any deprecated functions.
The sample covers Vertex Objects, Vertex Array Objects, Uniform and Attribute variables, shader setting, and definition of the camera and perspective matrices.

gDEBugger – OpenGL and OpenCL Debugger, Profiler and Memory Analyzer.
A must have tool. It profiles your code using OpenGL with GLSL, showing the number of function calls, your data on the graphics hardware, shaders, uniforms, vertex data, … you name it. You can establish breakpoints at OpenGL functions and run it function by function, or frame by frame. It does not require any additions to your code, and even tells you if you’re calling deprecated functions.

World’s Total CPU Power: One Human Brain | Wired Science | Wired.com.
“Our total storage capacity is the same as an adult human’s DNA. And there are several billion humans on the planet.”
“To put our findings in perspective, the 6.4*1018 instructions per second that human kind can carry out on its general-purpose computers in 2007 are in the same ballpark area as the maximum number of nerve impulses executed by one human brain per second.”
The above may be true, but computers, as opposed to humans, are always increasing their capacity and computational power. Furthermore it is easier to make a computer than a human being. It does make you think how things will be in … years (fill in the blank).

NAVI (Navigational Aids for the Visually Impaired) is project by master’s students Michael Zöllner and Stephan Huber at the University of Konstanz, Germany, aiming at improving indoor navigation for visually impaired by leveraging the Microsoft Kinect camera, a vibrotactile waistbelt and markers from the AR-Toolkit.

A new noise function for GLSL is being proposed by Ian McEwan at Ashima Art. It does not require any setup, i.e. no textures nor uniform arrays. Just add it to your shader source code and call it wherever you want. This means that it is easier to distribute the final shader so that it can be used in other application. It is based on Stefan Gustavson’s paper “Simplex noise demystified” and it runs on OpenGL 1.2 and up.

Advances in Real-Time Rendering in 3D Graphics and Games – SIGGRAPH 2010.
Siggraph’s courses are excellent, and definitely one of the main reasons to attend the conference. This particular course has been presented at Siggraph since 2006, and the slides for the 2010 edition are freely available. Continue reading »
