Free three dimensional software for mac

Clipboard Image Dimensions can quickly provide the width and height of an image held by the clipboard without leaving the current application.

It can be run with a script editor, from system-wide script menus, such as FastScripts and Apples script menu, and by other utilities that allow users to launch compiled AppleScript scripts.

Requirements:
Mac OS X 10.0 or later.

3 in Three 1.2 is the addictive puzzle game that you'll want to play again and again. One day in Corporate America, a freak power surge zaps the number 3 off her cozy spreadsheet home and into the heart of the computer where numbers don't count and the letters spell disaster.

Requirements: 256 colors

Requirements:
System 7.0 or later.

Requirements:
MacOS 8.0 or later or Decor. (control panel)

IsingCocoa provides an interface for running simulations of the Ising model of magnetically interacting spins on a 2-dimensional lattice. It is intended as a demonstration of the possibilities for interactive exploration of scientific models - the computing power available in modern machines is sufficient to perform sophisticated calculations on the fly as the parameters are changed.

In lesser words IsingCocoa simulates the Ising model of a ferromagnet

Particula Numerica in shortly Particula is an Gravitational N-Body Simulator. The software give you REAL-TIME three dimensional images for gravitationally interacting bodies, which are thought to be stars. REAL-TIME isnt meant real stellar time but you can see the MOTION of stars. The time indicated in the software is normalized time.

Particula can simulate the gravitational interaction of many bodies with certain initial conditions. You may set a simple homo-temperature spherical distribution model as an initial condition. The temperature and the number of the particles are able to be set. You can also use NEMO ASCII files as an initial data.

Particula provide you both two and three dimensional view. It shows you the overall 3D view of the particles. In 2D view you can see a trajectory of a certain particle and the temporal variation of potential energies (Kinetic/red and Potential/blue).

To update the 2D view you should click mouse with Ctrl key or the right mouse button. To change the line of sight in 3D view, just drag to rotate and shift-drag to zoom in/out.
