Freeware In 3D Modeling & Cad

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.

aeliom is not only a viewer. It is also a compiler, and allows user, via its language, to generate complete worlds. Finally, aeliom is a stand-alone renderer, that generates superb materials for each pixel.

Features:

• Aeliom is free for non profit use,
• compiler for the aeliom language (include a shader language),
• stand-alone high precision renderer,
• complex surfaces (high order, and Boolean ops),
• shadow generation,
• complex sky lighting,
• complex real time atmospheric volumetric effect (rays of light, fog, ),
• LOD for both the geometry and the materials,
• natural elements : water planes with ripples, volumetric clouds (with shadow projection), planar clouds, ...
• displacement mapping,
• view frustum culling (octree management), geometry coherency, portals, ...
• 3D sound environment,
• Ogg Vorbis codec support.

Download is also available for Windows 95/98/NT/2K. (6.1MB)

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.

A major advantage of Asymptote over other graphics packages is that it is a programming language, as opposed to just a graphics program.

Features:

• provides a portable standard for typesetting mathematical figures, just as TeX/LaTeX has become the standard for typesetting equations.
• inspired by MetaPost, with a much cleaner, powerful C++-like programming syntax and floating-point numerics;
• runs on all major platforms (UNIX, MacOS, Microsoft Windows).
• mathematically oriented (e.g. rotation of vectors by complex multiplication);
• LaTeX typesetting of labels (for document consistency);
• uses simplex method and deferred drawing to solve overall size constraint issues between fixed-sized objects (labels and arrowheads) and objects that should scale with figure size;
• fully generalizes MetaPost path construction algorithms to three-dimensions;
• compiles commands into virtual machine code for speed without sacrificing portability;
• high-level graphics commands are implemented in the Asymptote language itself, allowing them to be easily tailored to specific applications;

Features:

• Integrated GenBank search and viewing of sequences
• Multiple alignment of DNA, RNA, and proteins
• Open reading frame determination
• Translation from DNA to proteins (all genetic translation tables)
• Reports with residue composition, molecular weight and iso electric point (for proteins)
• Neighbor-joining and UPGMA phylogenies
• Restriction site analysis and viewing
• Other reporting and import/export facilities

Requirements:

• 256 MB RAM required
• 512 MB RAM recommended
• 1024x768 resolution recommended
