OverviewLucidus is a ray tracer and high dynamic range image viewer written in OCaml. It is structured as a tutorial, in a sequence of chapters that start out simple and work up to a complete system. ... [More] Later chapters build on the code and ideas of earlier ones, but each chapter is self-contained and has unit tests and/or applications that can be built and run. The tutorial assumes basic knowledge of OCaml, linear algebra, and ray tracing, though links are provided where appropriate. Lucidus can be seen as an advanced tutorial on functional programming and ray tracing. More than that, though, the goal is to demonstrate how to build a non-trivial software system that is readable, maintainable, and heavily tested. Ray tracing is the chosen subject matter and OCaml is the chosen language, but the focus is on solid engineering. ChaptersOverall Design Unit Tests Math Library Color Library Image Stream Library Progressive Rendering GUI Subprocess Library Subprocess GUI Complete HDR Image Viewer Antaliasing Sky Model in 2-d Camera Model Sky Model in 3-d Ray Intersection ... StatusOnly very preliminary code is checked in, focusing mostly on the image viewer side of things. The tutorial aspect will only take shape once the code structure had matured, and the code structure is in a very early phase. [Less]

Many various "game engines" exist, already, as well as various and assorted renderers using opengl. However, many of them incorporate HDR as a postprocess "afterthought" and many incorrectly. ... [More] Furthermore, most do not include any notion of a "pipeline" for content creation, and simply want to make games. Soaper is different, in that it aims to be a very fast modern rendering engine and associated content creation tools to allow for an emphasis on physical correctness of content, based both on computer vision and modern image-based graphics, without many dependancies on third-party tools or code bloat.

PixelToaster is a library for C++ programmers who want to write their own software rendering routines, reading and writing to an array of pixels. You choose between high dynamic range floating point ... [More] color or 32 bit truecolor and pixeltoaster converts to the native display format automatically. You also get basic keyboard and mouse input and a high resolution timer. PixelToaster is designed by Glenn Fiedler, author of the PTC, OpenPTC and TinyPTC libraries. If you liked PTC, you'll love PixelToaster! [Less]

This Plugin consists of several sub routines. Currently planned are a stack builder to build stacks of the images that should be combined into a single HDR image, a response function calculator and a ... [More] tone mapper supporting various tone mapping algorithms. [Less]

HDR image and video compositing

Mise en oeuvre de JAI, application à la photographie HDR

Loggbok2008-03-13 Började skrapa lite på ytan med att ta fram kamerakurvan. Hittade ett klassbibliotek som verkar smidigt för att hantera matriser: http://math.nist.gov/javanumerics/jama/. ... [More] Testade med en linjärregression och det fungerade utmärkt. Ska nog inte bli några problem det här! 2008-03-07 Skrev om GUI och lade till en jFileChooser som poppar upp när man trycker på "importera HDR". Filen sparas i en variabel file och skickas sedan till readHDR. Statuspanelen uppdateras oxå... La även till ikoner till importeringsknapparna. /Tobias [Less]

ToneMapper is a Cocoa GUI application for Mac OS X, implementing most of state-of-art tone mapping operators for HDR images, as well as some novel approaches to tone mapping problem proposed in my Computer Science master's degree work.
