Compact Normal Storage for small G-Buffers

jstone — Mon, 16 Nov 2009 03:07:00 -0500

Various deferred rendering or deferred lighting approaches need to store normals as part of their g-buffer. Let's figure out a compact storage method for view space normals Tagged by jstone under math, geometry, computer.graphics, gpu, programming, reference, rendering,

OpenSCAD - The Programmers Solid 3D CAD Modeller

jstone — Fri, 06 Nov 2009 10:24:00 -0500

OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and Apples OS X. Unlike most free software for creating 3D models (such as the famous application Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies. OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file (see examples below). This gives you (the designer) full control over the modelling process and enables you to easily change any step in the modelling process or make designes that are defined by configurable parameters.

HIPR - Image processing learning resources

jstone — Mon, 19 Oct 2009 06:24:00 -0400

The Hypermedia Image Processing Reference (HIPR) was developed at the Department of Artificial Intelligence in the University of Edinburgh in order to provide a set of computer-based tutorial materials for use in taught courses on image processing and machine vision. The package provides on-line reference and tutorial information on a wide range of image processing operations, extensively illustrated with actual digitized images, and bound together in a hypermedia format for easy browsing, searching and cross-referencing.

Build Your Own 3D Scanner: Optical Triangulation for Beginners

jstone — Thu, 08 Oct 2009 07:07:00 -0400

This course provides a beginner with the necessary mathematics, software, and practical details to leverage projector-camera systems in their own 3D scanning projects. An example-driven approach is used throughout; each new concept is illustrated using a practical scanner implemented with off-the-shelf parts. The course concludes by detailing how these new approaches are used in rapid prototyping, entertainment, cultural heritage, and web-based applications.

Processing.js

jstone — Wed, 23 Sep 2009 11:20:00 -0400

Processing.js is an open programming language for people who want to program images, animation, and interactions for the web without using Flash or Java applets. Processing.js uses Javascript to draw shapes and manipulate images on the HTML5 Canvas element. The code is light-weight, simple to learn and makes an ideal tool for visualizing data, creating user-interfaces and developing web-based games.

Mean Shift Filter

jstone — Fri, 11 Sep 2009 03:21:00 -0400

This plugin is a very simple implementation of a mean shift filter that can be used for edge-preserving smoothing or for segmentation. Important edges of an image might be easier detected after mean shift filtering. Tagged by jstone under image.processing, research, algorithm, computer.graphics, reference,

Open Emu

jstone — Tue, 23 Jun 2009 01:09:00 -0400

Open Emu is an open source project to bring game emulation to OS X as a first class citizen, leveraging modern OS X technologies such as Cocoa, Core Animation and Quartz, and 3rd party libraries like Sparkle for auto-updating. Open Emu is based on a modular architecture, allowing for game-engine plugins, this means Open Emu can support a host of different emulation engines and back-ends while retaining a familiar OS X native front-end.

Gloss: a Pygame OpenGL wrapper

jstone — Wed, 10 Jun 2009 09:33:00 -0400

Gloss is a high-performance graphics wrapper around Pygame that lets you take advantage of OpenGL without having to delve into the murky depths of 3D programming. Gloss lets you build 2D games where you can rotate, scale and recolor sprites on the fly, and also includes a selection of helpful mathematics functions to make the life of games coders easier.
