GLSL 1.2 Tutorial In this tutorial shader programming using GLSL 1.2 will be covered. Although many parts are now considered deprecated, the essence of GLSL has remained constant. Besides, this tutorial will continue to be online because learning the basics of deprecated OpenGL is easier than learning the new versions. Shaders are a hot topic and 3D games have shown that they can be put to good use to get remarkable effects. The tutorial contains an introduction to the specification, but reading the OpenGL 2.0 and GLSL official specs is always recommended if you get serious about this. GLSL stands for GL Shading Language, often referred as glslang, and was defined by the Architectural Review Board of OpenGL, the governing body of OpenGL. I won’t go into disputes, or comparisons, with Cg, Nvidia’s proposal for a shading language that is also compatible with OpenGL. Before writing shaders, in any language, it is a good idea to understand the basics of the graphics pipeline. Index The Graphics Pipeline Notes

Researcher Jean Lorenceau's system allows users to trace letters, numbers, figures, signature, and even make drawings as if they were using a pen. Mr Lorenceau, who works in the government-backed CNRS research institute of the brain and spinal cord, says it is a breakthrough for people trapped in immobility by disease or accident. "For persons deprived of limb movement, this offers a fast, creative and personal means of linguistic and emotional expression," said Mr Lorenceau's report, published in the journal Current Biology. Using a head-mounted camera, an eye tracker records eye movements and calculates the gaze direction of the subject. Mr Lorenceau's system, still just a prototype, compensates for erractic or jumpy eye movements to allow a smooth writing style.

WebGL Inspector An advanced WebGL debugging toolkit About WebGL Inspector is a tool inspired by gDEBugger and PIX with the goal of making the development of advanced WebGL applications easier. Note: this is alpha software - if you find bugs, let me know (or better yet, fork and fix them! Check out the readme on github for more information. Status There hasn't been an update in awhile, but the project is not dead! Features Extension for injecting into pages Embed in an existing application with a single script include Capture entire GL frames Annotated call log with stepping/resource navigation and redundant call warnings Pixel history - see all draw calls that contributed to a pixel + blending information GL state display Resource browsers for textures, buffers, and programs Live Demo Click here to view a live demo (in a browser that supports WebGL, of course): You can embed the inspector on your own pages like this if there is no extension for your browser or if you don't want to install it.

Born to Learn ~ You are Born to Learn Database of Periodic Tables There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach. Harrington Periodic Tables So we start this effort tabula rasa (without preconceived ideas). 1) All atoms have a default "common denominator" structure at 270 mass units, irrespective of the element under discussion. Top of Page KAS Periodic Table The KAS periodic table reproduces and depicts the nuclear properties of chemical elements. The Segre Chart is based on the number of protons, Z, and the number of neutrons, N. Location that remains near the Neutron Dripline of element. Read more here, here and here.
