SNT's Reconstruction Viewer is a powerful OpenGL 3D visualization tool for both surface meshes and reconstructions

  • It can be used as a standalone program or from withing SNT
  • Features:
    • Advanced rendering supporting axes, transparency, color interpolation and path smoothing
    • Interactive scenes (controlled rotations, panning, zoom, scaling, animation, "dark"/"light" mode)
    • Tools for management and customization of scene elements
    • Ability to render both local and remote files on the same scene
    • Loading of surface meshes of several template brains (Drosophila and Allen CCF (Allen Mouse Brain Atlas))

Starting the Viewer

The Reconstruction Viewer may be used as either a stand-alone program or from within SNT. To open Reconstruction Viewer as a stand-alone program, go to Plugins › NeuroAnatomy › Reconstruction Viewer. To open the program from within SNT, use the "Open Reconstruction Viewer" option in the 3D tab of the SNT dialog. If there are any tracings currently loaded in SNT, they will be displayed in Reconstruction Viewer after opening. Note that, for performance reasons, some Path Manager changes may need to be synchronized manually from RV controls.
