GL - Transformations. Since this is a guide on graphics programming, this chapter will not cover a lot of the extensive theory behind matrices. Only the theory that applies to their use in computer graphics will be considered here and they will be explained from a programmer's perspective. If you want to learn more about the topic, these Khan Academy videos are a really good general introduction to the subject. A matrix is a rectangular array of mathematical expressions, much like a two-dimensional array. Below is an example of a matrix displayed in the common square brackets form. [a = \begin{bmatrix} 1 & 2 \\ 3 & 4 \\ 5 & 6 \end{bmatrix}] Matrices values are indexed by (i,j) where i is the row and j is the column.
To get a bit more familiar with the concept of an array of numbers, let's first look at a few basic operations. Addition and subtraction Just like regular numbers, the addition and subtraction operators are also defined for matrices. Scalar product Translation Scaling Rotation Rotation around X-axis: Mrb: Message-Passing and Concurrent Program Design.
Message-Passing and Concurrent Program Design After a thorough discussion of the semantics and application of declarative concurrency in chapter 4, Van Roy and Haridi turn their attention to an alternative design solution for the same challenging problem space. Chapter 5, "Message-Passing Concurrency" covers the necessary changes to the kernel language to make this kind of programming possible, discusses the design of programs using this paradigm, and takes a brief aside to look at the Erlang language and its OTP framework. Beyond covering the technical aspects of concurrency, the authors also emphasize the application of these concurrency primitives as design solutions for particular kinds of problems. Concurrent program design, reasoning, and proofs are given a fair amount of treatment, and attention is paid to the realism of applying the ideas as they are presented in the book.

WebGL for Chemistry Part 1: Introduction | Metamolecular. 3D graphics play a vital role in a large amount of scientific software. Until very recently, however, Web browsers offered little in the way of powerful tools for the creation of compelling 3D graphics software. All Articles in This Series About WebGL WebGL™ changes all of this. WebGL is a cross-platform, royalty-free web standard for a low-level 3D graphics API based on OpenGL ES 2.0, exposed through the HTML5 Canvas element as Document Object Model interfaces. The novelty of WebGL means that documentation, although available if you know where to look, is somewhat jumbled. This article is the first of a technically-oriented, in-depth series on the application of WebGL to chemical data visualization problems. WebGL-Enabled Browsers Currently, Chrome is the only major browser to support WebGL by default.
Support for WebGL on Internet Explorer is unlikely, at least for the upcoming IE9 release. A High-Level API for WebGL PhiloGL is a new JavaScript toolkit for working with WebGL. A Goal. HelloRun™ 3D Particles Made of Light - AS3 Flash Effect. Thousands of particles which appear to be made of light form beautiful surfaces in 3D space. We use an additive luminescent effect which creates brighter spots where particles are more concentrated. We present four examples with variations in color and filter effects.

Particles made of light form parametric surfaces We present four variations of a new particle example using pixel-based particles in three dimensions.
In our earlier examples, the particles were considered as opaque objects. Here, however, we have done away with z-sorting (which saves some CPU), and instead we allow the brightness of overlapping particles to add together. Comments on the code Here is how it works. Level = (readColor & 0xFF)+levelInc; SculptGL - A WebGL sculpting app. We made you look - Spherical Harmonics Distortion - First experiment in WebGL. Spherical harmonic distortion.
Bruno imbrizi : experiments. Demo3d. Babylon.js: a complete JavaScript framework for building 3D games with HTML 5 and WebGL - Eternal Coding - HTML5 / Windows / Kinect / 3D development. /* Updated on 4/10/14 to reflect API changes */ I am a real fan of 3D development. Since I was 16, I spent all my spare time creating 3d engines with various technologies (DirectX, OpenGL, Silverlight 5, pure software, etc.). My happiness was complete when I discovered that Internet Explorer 11 has native support for WebGL. So I decided to write once again a new 3D engine but this time using WebGL and my beloved JavaScript. If you are a 3D beginner, I suggest you to read this excellent series of blogs written by my friend David Rousset: Thus babylon.js was born and you can find some samples right here: You can also find all the sources on Babylon.js Github repository: The engine is currently at early stage but I plan to add a lot of cool new features quickly.
And the result: Drone Tank Arena. Looking to move from Flash to WebGL? IvanK brings the Flash API to JavaScript. Ivan Kuckir sent in a neat library to help Flash developers move to JavaScript. I have made a graphics library to help people move from Flash to Javascript. It is something like EaselJS, but unlike EaselJS, all the classes, methods and properties come from Flash and unlike EaselJS, it uses WebGL (GPU) for drawing graphics (it is fast).
As he says, the API is heavily based on Flash so it will be very familiar to Flash developers. The library supports many common things, including a scene graph for mouse events over individual elements (not possible with plain WebGL without lots of work), text rendering, images, vectors and more. There are some library demos, but Ivan has gone even farther and made two fun games with it that certainly show the library’s power and performance. While the library is heavily based on Flash and he says Flash developers will have no trouble picking it up, it does have some documentation of its own for you to get started, and of course the demo source code.
