Free 3d model view software for mac

This Audio Unit (AU) OSX plugin will please all musicians searching for warm classic echo effects to the strangest modulations and musical patterns.
Users can indefinitely "Model" their sounds and sequences with unlimited random modulation tweaks, powerful filtering and weird ring modulations.
Main features:
- Stereo to Stereo processing
- 1ms to 1000ms delay time.
- 5 types of modulators.
- Random generated patterns with smooth function
- Envelope follower
- Decimator
- Ring modulator
- Low & High shelf filter in feedback path
- Lowpass filter in crossfeedback path
- Parameters randomizer.
Enhancements:
- User defined modulation by drawing
- New modulation types (Chaosc, FM)
- Sound capture from the host
- Selectable number of random pattern steps
- New skin (thanks to Chad Tomlinson).

MODELLER is used for homology or comparative modeling of protein three-dimensional structures. The user provides an alignment of a sequence to be modeled with known related structures and MODELLER automatically calculates a model containing all non-hydrogen atoms.
MODELLER implements comparative protein structure modeling by satisfaction of spatial restraints, and can perform many additional tasks, including de novo modeling of loops in protein structures, optimization of various models of protein structure with respect to a flexibly defined objective function, multiple alignment of protein sequences and/or structures, clustering, searching of sequence databases, comparison of protein structures, etc.
Note: In order to use the program you need to register first.
Enhancements:
- Removal of limits on the number of pseudo atoms, segments, the length of file names and most other strings, and the number of parameters in parameter files.
- Removal of the read_restyp() command. To read a user-defined residue type file, set restyp_lib_file when creating an environ object.
- Bug fix: the correct VDW radii (as selected by topology.submodel) are now used for PSA calculations (previously the all-hydrogen radii were used in all cases).
- Improved error handling: almost all errors should be recoverable now (using the standard Python exception handling mechanism) and incorrect input should trigger an error rather than causing Modeller to crash (please report any crashes as bugs to the developers).
- SALIGN bug fixes, improved binning of access classes.
- Modeller scripts are now more like real Python scripts; the PYTHONPATH environment variable is honored, and additional command line arguments can be given to your scripts (accessible as sys.argv).
- Bug fix for alignment.segment_matching(): correct alignment scores are now written.
- Support for AMD64 and EM64T (Opteron/Xeon64) Linux machines.
- DOPE model assessment now returns only the DOPE energy itself by default, ignoring other energy terms.
- Bug fix for model.restraints.pick() when used with absolute position restraints; always allow 1-atom restraints to pass the residue_span_range check.

The Draggable View Cocoa example demonstrates how to allow a user to drag an image view contained in an NSScrollingView with the mouse.

Completly freeware for non-commercial use.

3DPlotterGL is a 3D plotting plug-in for pro Fit based on OpenGL.
3DPlotterGL lets you use OpenGL to produce 3D models of data and functions from within pro Fit by installing three commands in the "Prog" menu.
The commands allow to produce a 3D model of a surface plot or a scatter plot from data in a pro Fit spreadsheet, or directly from a function definition.
The 3D model can be interactively turned around and edited, and the result stored into a pro Fit drawing window.
Enhancements:
- This is a maintenance release of the 3D plotting plug-in for pro Fit. It corrects some bugs in version 1.2.5 and provides an additional choice of one-dimensional textures.

SMViewer is an utility to visualize 3D models saved in the DXF format.
SMViewer imports almost every DXF primitives :
- 3DFACE
- POLYLINE : be it a grid, a mesh or a polygon
- 3DLINE.
Enhancements:
- Works on Mac OS X 10.0 (This version wont run on Mac OS X Public Beta).
- Addition of a progress bar to make user wait while loading big DXF files (> 8 MB)
- Modification in the OpenGL code
- Cool icon for DXF files
- Correction on the Open Panel to keep the last used directory.
- Source code is available. For the moment, its a total mess in the way file are in 2 folders.
