IMOD

IMOD Image modeling program package.

View 3-D Graphic Data

IMOD reads and displays 3-dimensional graphic data in the MRC file format. Tools are provided for translating raw images, RGB files, and simple TIFF files into the MRC format.

The main window of IMOD shows slices of a 3-dimensional graphic volume along the X,Y and Z axis in three linked views. Selecting a point in one view will automaticlly find the point in the two other views. Each of the three views can be movied forwards or backwords.

Additional views include: a view of the selected point in a tilt series, a view of a slice through the 3-D graphic data, a view of a small sub volume of the 3-D graphic data, projected in real time. Image intesity graphs can be opened for the x, y and z axis.

Modeling

Models can be created manually using the mouse or segmented by using thresholding. Models are structured into objects for easy editing. Model files can be transfered to NFF, Wimp or SYNU data formats.

Models can be viewed in real time wire frame rendering with hidden line removal. Models can also be viewed in cross-eyed or wall eyed stereo. Control of rotation, translation, magnification and transparentcey is interactive. Image data inside of the contours can be colored and rendered into a movie rotating about the x, y or z axis. Volume and surface area calculations can be calculated from the model.

Presentation

A seperate viewing program allows easy slide and movie making cababilities. Titles and multiple text fonts can be added to images.

Requirements

IMOD has been tested on a Personal Iris 4D/20 and an Indigo R4000. Most of the programs require 24 bit graphics. There should also be enough memory to load the entire contents of a 3-D graphics file for best performance.

Availability

IMOD excecutable is available free to anyone who wants it.

IMOD source will be available free with certain restrictions.
