Visit the official Blender website.

Blender is an advanced 3D graphics modeling program capable of producing high quality animations, performing rendering, post-production, interactive creation and playback. It is the only 3D creation suite which allows the artist to model, texture, animate, render, and export the finished product in a package less than 10 MB.The active development community is steadily adding new features and extensions such as the superb Yafray rendering engine for generating photo-realistic effects. Blender natively exports to a multitude of 3D formats such as VRML, Cal3d, AC3D. With the powerful and easily extensible Python plugin support, you can write your own extensions or choose from a range of existing plug-ins.3D modeling remains a complex computing task, with the result that Blender is an extensive application with a steep learning curve.

Visit the official Dia website.

Dia can be used to draw a variety of diagrams to suit your needs, such as entity-relationship models, UML diagrams, flowcharts, network diagrams, and simple circuits.

It can load and save diagrams to a custom XML format, and export diagrams to a number of formats including EPS, SVG, XFIG, WMF and PNG. You can also print diagrams, including those that span multiple pages.

Visit the official GIMP website.

The GIMP (or GNU Image Manipulation Program) is suitable for those wanting to manipulate digital photographs, design and export graphics for the web, convert images from one file format to another, or even produce complex high-resolution compositions for print. The GIMP features a number of paint tools with sub-pixel sampling for high quality anti-aliased brush strokes, a powerful gradient editor and blend tool, layers and layer masks with over 20 blending modes, support for importing and exporting in a myriad of image formats, unsharp mask, levels and curves tools for enhancement of digital photos and much more!

The GIMP is a feature-packed program which may seem overwhelming at first. We suggest referring to the manual and tutorials available from the Gimp web site.

The GIMP uses the GTK+ library which is also available on OpenDisc. It won’t work without it, so ensure to install GTK+ first.

Visit the official Inkscape website.

Inkscape is an easy to use vector graphics editor that uses the Scalable Vector Graphics (SVG) file format. Supported SVG features include shapes, paths, text, markers, clones, alpha blending, transforms, gradients, patterns, and grouping. Inkscape also supports Creative Commons meta-data, node editing, layers, complex path operations, bitmap tracing, text-on-path, flowed text, direct XML editing, and more. It imports formats such as JPEG, PNG, TIFF, and others and exports PNG as well as multiple vector-based formats.

You can use Inkscape to create diagrams for reports and projects. Because Inkscape uses “vector” rather than “raster” graphics editing (which is mostly used by the GIMP), you can always go back later to reposition items and change font sizes. More importantly you won’t end up with blocky graphics because with vector graphics you can enlarge the images to any size without losing quality.

Visit the official Nvu website.

Nvu is a fully featured What-You-See-Is-What-You-Get (WYSIWYG) web page editor, enabling you to create compelling web pages without having to devote months to learning HTML.
