Art of Illusion is a free, open source 3D modelling and rendering studio. It is written entirely in Java, and should be usable on any Java Virtual Machine which is compatible with J2SE 1.4 or later.

Art of Illusion is powerful enough to be used for serious, high end animation work. Many of its capabilities rival those found in commercial programs. Some of the highlights include subdivision surface based modelling tools, skeleton based animation, and a graphical language for designing procedural textures and materials.

Iris is a software that offers numerous and powerful functions of image processing in the field of the digital astronomical images. Iris is particularly optimized to exploit the images that come from CCD cameras.

Iris will load and save pictures in the formats FITS, PIC (proprietary format), raw or BMP. Iris can read also the images of the Buil-Thouvenot Atlas, a CD-ROM which contains 4649 images of 6600 objects of the deep-sky.

From the Command window you can execute numerous commands in on-line mode. The on-line mode of Iris is extremely practical, notably to make repetitives operations. When you will master it you will have a powerful productivity tool in hand.

Finally, Iris possesses functions helping the Audine CCD camera construction. The project Audine was developed by the Association of the Users of Electronic Detectors (AUDE). Iris is a part of this project.

Version 5.53 now supports the 48-bit FITS format (true color, 3 x 16 bits), as well for input and output. The functionality available in the PIC format proprietary PIC are also now available with the FITS. The PIC format retains some an advantage in terms of disk loading and saving speed.

Astrometric calibrated FITS images are now compatible with WCS (World Coordinates System). WCS can map pixels in the image to right ascension and declination on the sky.

What's New in version 5.55:

• Improved Lumenera camera acquistion (addition of 12-bits video).

DeleD is a 3D modeler and level-editor combined into one and is specifically designed to create static objects/worlds. It unites the functionality needed to create complex 3D scenes with an easy-to-understand userinterface: build entire worlds within an hour!

The concepts behind DeleD are simple. Draw and manipulate 3D objects like cubes, polylines, spheres, rectangles, grids, pyramids, cylinders and more. Combine them into new 3D objects and use those to create complete scenes. Then use various types of lights like spotlights, directional lights or pointlights to bring your scene to life!

Anything you create with DeleD, either by using the LITE or the PRO version is license free. This means that you can use whatever you make with DeleD for your own purposes, whether commercially or not. No license fees, no legal strings.

Whatever you create with DeleD, is yours to use.

Download the free Autodesk DWF Viewer to easily view and print 2D and 3D drawings, maps, and models in DWF— the ideal way to share data-rich design files. Only DWF is purpose-built for distributing CAD files and 3D models so the fidelity and intelligence of designs can be communicated securely, including object and mass properties, sheets, and layers. Often at 1/10 the size of other formats, DWF files are easy to distribute and post online. Plus, with one-click publishing from AutoCAD software and other design applications, and the free Autodesk DWF Writer, there’s no need to buy additional software.

New features include the ability to view and print 3D models from 12 Autodesk design applications including Autodesk Inventor, AutoCAD, Autodesk Architectural Desktop, Autodesk Revit, and 3Dsmax. Also included is a new print preview feature to see how the drawing will print before hitting "print", tight integration with leading large format printer suppliers, HP and Oce, including new HP Instant Printing feature to optimally print to a connected HP Designjet printer, and greater support for design intelligence including block attributes and properties from AutoCAD, and new MapBooks from Autodesk Map 3D.

20-sim is an advanced modeling and simulation package for Windows. With 20-sim you can simulate the behavior of dynamic systems, such as electrical, mechanical and hydraulic systems or any combination of these. 20-sim models may use iconic diagrams, bond graphs, block diagrams as well as differential equations. Used in mechatronics, control engineering, robotics, mechanical engineering, hydraulics etc.

This is the full demonstration version of 20-sim 3.2 Pro! This demonstration version is a free full-working viewer. This means that all 20-sim toolboxes and libraries are available, and there are no restrictions on the number of submodels or states. This viewer allows you and your collegues to view and simulate 20-sim models. Get the functionality of Simulink from the same lab as Tutsim.

A general purpose 2-dimensional CAD program. It supports industry standard DWG/DXF drawing formats. With A9CAD you can draw shapes such as line, rectangle, circle, poly-line, text and dimension; performing drawing modifications like move, scale, rotate, explode, trim, fillet and mirror; edit color, fill mode, line type and line width; change entity attributes via properties window. Manage drawing styles and settings and configure drawing environments.

Version 2.2.1 includes minor bug fixes.

Google SketchUp is an easy-to-learn 3D modeling program that enables you to explore the world in 3D. With just a few simple tools, you can create 3D models of houses, sheds, decks, home additions, woodworking projects - even space ships. And once you´ve built your models, you can place them in Google Earth, post them to the 3D Warehouse, or print hard copies.

A complete 3D modeling application for computing aided drafting in three dimensions. AutoQ3D can be used by anyone who wants an easy way to imagine, create, and publish in 3D. It is ideal for you to use as modeling editor for your home additions, game design, math geometrical education or whatever your imagination tells you.

Visual Terrain Maker is a 3D-Modeling program that allows to visually create landscapes (maps) for games or other purposes. Works in XP/NT/2000/2003. The program can export to Direct X® file format(*.x). The program is not critical to the video adapters and drivers. Suitable for Dark Basic developers.

Alibre Design Xpress is a rich and capable 3D solid modeler for creating mechanical parts, assemblies and 2D drawings. Alibre Design Xpress equips the person needing basic 3D design capabilities. The genius of Alibre Design Xpress lies in its inherent ease-of-use. Those that are new to 3D will find the tutorials, help and user interface intuitive to learning how to build 3D designs.

DesignBots is a design environment for robotics. It will function as a 3d game development environment as well. Or you can just use it for basic 3d CAD.

Linear and rotational motors are supported. You can use as many unmotorized parts as are required in your design as well. You can create reusable parts composed of subparts which are parts composed of subparts to any complexity.

While constructing your robot you indicate which parts are motorized and simulate motor motion to ensure your design is functioning properly. When you are done, bot will search through your design to gather information on all the motors you´ve installed and presents you with a ´Control Motors´ interface that allows you to manipulate any motor position and see the graphical result.

The design is provided with the download as an example. Manipulating the values in the ´Control Motors´ form allows you to graphically simulate motor motion and test your design. The ´Spin Value´ form increments values to so you can animate your design with the mouse.

VectorEngineer is a 2d cad system originally developed as a technical drawing program to produce working drawings for engineering projects. It´s perfect for quickly drawing out your idea or making complicated drawings of that future HoverBoard your going to build. If you´re like me, my paper drawings look more like a five year-olds picture of a whale then plans for a HoverBoard. This program makes it super easy to be neat and organized, by allowing you to set up a customized grid that the mouse can snap-to. If your looking for a 3D CAD program that requires training to use, then look elsewhere; But if your looking for an easy and effective CAD program for the average-Joe, then you need this program.

Create 3D models, edit color, create and animate almost anything. This software is free with no spyware, adware, trojans - just freeware. Once a very expensive program, but has been made free.
