QML (Quantity Modeling Language) is a "thing"-based language for scientific and mathematical data modeling.
Each "thing" is a quantity which may be associated with either a structure or physical phenomena.
Quantities, in turn, may hold other Quantities or values (numbers or strings). Higher-level data models, which associate or define meanings to various quantities (such as velocity or position), can be built from QML quantities.
The higher-level data model (XML) schema that inherits from QML may be understood, and its instance documents may be parsed into QML documents and objects by the QMLReader.
Enhancements:
- This release adds partial Xerces2 DOM support, and works with Java 1.4 and Java 1.5 (no JAXP DocumentBuilder/Factory support currently).
- The test procedure is a little less chatty.
- Support has been added for testing either/both Crimson/Xerces DOM support.
- (Note: Crimson support only works with Java 1.4, as Java 1.5 interfaces have DOM lvl 2 and 3, which crimson doesnt support).
- This release adds compilerargs, and better build support for different configurations to build.xml.

Misfit Model 3D is an OpenGL-based 3D model editor that works with triangle-based models. Misfit Model 3D supports multi-level undo, skeletal animations, simple texturing, scripting, command-line batch processing, and a plugin system for adding new model and image filters.
Complete online help is included. It is designed to be easy to use and easy to extend with plugins and scripts.
Misfit Model 3D was written and tested on Linux (2.4 and 2.6 kernels) and has been compiled and tested on most major Linux distributions.
It is not endian-safe so it is unlikely to run on non-x86 hardware platforms--this will probably not change soon unless I get requests for a version thats usable on big-endian archs.
Enhancements:
- The menus have been re-organized. There is a new command to make normals face outward. The texture coordinate window now has a rotate tool. Material support for COB has been improved. Many animation bugs have been fixed. A "File | Export" command has been added to indicate which formats have less reliable write support.

OMF (OpenBlueLab Modeling Famework) created by and for OpenBlueLab permit to configure easily the portal. Actually, we must use ArgoUML or the plugin ArgoEclipse with the IDE Eclipse. The goal is to create a specialized editor to create the diagrams needed by OpenBlueLab to configure the portal.
The main steps are :
- Transformation files generated by ArgoUML (XMI format) to the ECORE format.
- Transformation files from ECORE format to XMI format (or PIVOT format) to configure the portal.
- Creation of the editor.
Enhancements:
- This version integrates the transformation to UML2, and adds a dialog on comments in the class diagram.

Model3D::WavefrontObject is a Perl extension for reading, manipulating and writing polygonal Alias Wavefront 3D models.

SYNOPSIS

use Model3D::WavefrontObject;
my $model = Model3D::WavefrontObject->new;
$model->ReadObj(blMilWom_v3.obj);
$model->Rotate(x => 45, y => 15);
$model->Scale(135%);
$model->WriteObj(V3_modified.obj);

Model3D::WavefrontObject allows a polygonal Alias Wavefront Object file to be loaded into memory, manipulated, analysed, and re-output.

At this time the model only supports the polygon functions of the Wavefront Object format, not bezier splines, procedural surfaces, and so on. It is currently coded only far enough to support the sorts of Wavefront Object meshes that are also supported by the Poser 3D animation program, and of the sort exported by 3DSMax by using the HABWare exporter.

It supports groups and materials, but not multi-grouped polygons (only the first group is recognised if a polygon is declared to be in multiple groups).

Polygons with greater numbers of vertices are supported, even though these are not supported by the Poser software.

The models will also recognise (and support) the Region extension to the format as defined by Steve Coxs UVMapper and UVMapper Pro program. As a result, it may well be the only piece of code that writes Wavefront Objects without leaving these out.

OpenCSG project is a library that does image-based CSG rendering using OpenGL. OpenCSG is written in C++ and supports most modern graphics hardware using Microsoft Windows or the Linux operating system. OpenCSG-1.1.0 is the current version.
What is CSG, anyway? CSG is short for Constructive Solid Geometry and denotes an approach to model complex 3D-shapes using simpler ones. I.e., two shapes can be combined by taking the union of them, by intersecting them, or by subtracting one shape of the other. The most basic shapes, which are not result of such a CSG operation, are called primitives. Primitives must be solid, i.e., they must have a clearly defined interior and exterior. By construction, a CSG shape is also solid then.
Image-based CSG rendering (also z-buffer CSG rendering) is a term that denotes algorithms for rendering CSG shapes without an explicit calculation of the geometric boundary of a CSG shape. Such algorithms use frame-buffer settings of the graphics hardware, e.g., the depth and stencil buffer, to compose CSG shapes. OpenCSG implements a variety of those algorithms, namely the Goldfeather algorithm and the SCS algorithm, both of them in several variants.
Benefits:
CSG is often used as fundamental modeling technique in CAD/CAM applications. Here, image-based CSG rendering is the key to interactively manipulate CSG shapes. Since OpenCSG renders even complex CSG shapes fast, it can be advantageously used in such applications.
Raytracers such as PovRay have used CSG for shape modeling since long ago. Interactive modeling toolkits for such raytracers normally just ignore CSG commands, though. OpenCSG represents a valuable addition for such applications.
Overall, up to the present CSG rendering has been hardly used in interactive applications, since the necessary algorithms are complicated and error-prone. We hope that by providing a free library that is easy to use, fast, and versatile, CSG rendering can be made more mainstream than it currently is.
Usage:
The interface of OpenCSG is very easy to use. There is only a single abstract class called OpenCSG::Primitive. A Primitive object has an attribute Operation that denotes whether the primitive is intersected or subtracted. To use OpenCSG, create a derived concrete primitive class by implementing the render() method.
To actually do the CSG rendering, there is the function OpenCSG::render() that takes a std::vector as argument. The render function evaluates the CSG expression given by the array of primitives and initializes the z-buffer with the proper values for the CSG expression. The color buffer remains unchanged, so afterwards, you must shade the primitives in the array using a GL_EQUAL depth function.
Note that the render function does not evaluate a generic CSG tree that also would contain unions of CSG shapes. It has been shown that a generic CSG tree can be converted into an equivalent set of CSG expressions that the render function can handle. OpenCSG does not contain the functionality for this conversion since, after all, it is a rendering library.
Enhancements:
- OpenCSG can now use OpenGL frame buffer objects as an alternative to pbuffers to do the internal CSG rendering calculations.
- This potentially reduces the rendering overhead because no switching between different rendering contexts is required.
- Several other bugs have been fixed.

ACFTools project is an utility for manipulating X-Plane ACF and WPN files.

ACFTools is a utility for manipulating X-Plane flight simulator aircraft and weapon models without using its Plane Maker. It can decode both Apple and Intel ACF/WPN formats into plain text files with a syntax similar to C, which can be edited and then re-converted into binary data.

It is able to extract almost complete 3D models of aircraft (fuselage, floats, tanks, wings, stabs, propellers, engines) and write it in AC3D modeler format. Edited 3D parts can then be merged into plain text and consequently converted into binary ACF files.

Allows you to:
- export X-Plane (www.x-plane.com) aircraft data files to human-editable plaintext format and 3D mesh editable in AC3D modeler (www.ac3d.org).

- import plaintext/3D mesh back to ACF file.
