OpenGL 3.3 + GLSL 1.5 Sample

by

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, … Read more

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 … Read more

Kinect – Aiding Blind to Navigate

by

  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.

Noise for GLSL

by

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.
