3-D Display

Introduction

Jim can display images interactively in a three-dimensional view. It can display various types of three-dimensional image information, and can combine all these types of view into a single composite display. It can display:

  • Three orthogonal planes through the data set.
  • An extracted iso-intense surface (iso-surface). You set the intensity of the surface you want to display.
  • A volume rendering. For visualising 3D internal structures by assigning colour and transparency (opacity) to each voxel.
  • Regions of interest - either as outlines in 3-D space, or as a rendered surface created from the ROIs.
  • Almost any object can be displayed if it is defined using one the 3-D solid object modelling formats. Various tools in Jim can create Virtual Reality Modelling Language (VRML97) object files, including the Brain Finder and the Fuzzy Connector. Here is a good starting point to find out more about VRML97.

You can add as many of these 3-D display elements as you wish (subject to computer memory limitations) to create the view that you want.

Below is an illustration of what can be achieved in just a few seconds.

To start Jim's 3-D display, select 3-D Viewer from the Toolkits menu: Launching the 3-D viewer

The empty 3-D Viewer frame will now appear, ready for you to add the elements you wish to display.

Now select the types of element you want to add from the File menu.
