Overview
Display Options
The program renders stacks of images in back-to-front order, combining them using alpha blending or maximum intensity projection (MIP) and user-defined transfer functions. A single image stack may be rendered, or a set of stacks from a time-lapse study may be sequentially rendered (aka 4D microscopy). While rendering is occurring, you may modify the transfer functions (i.e. color and opacity tables),viewpoint (i.e. rotation, scale, translation), or rendering mode (i.e. alpha or MIP). And rendered images may optionally be displayed using anaglyph stereo (which requires the user to wear red-cyan or red-green glasses).
 
File Formats
The program can load and display multi-channel 8-bit image stacks from Bio-Rad PIC, Zeiss LSM, Metamorph STK, TIFF, and raw/binary files. Higher precision (e.g. 12 bits per channel) images are not supported in this release, but we hope to have this in the next release. In the meantime, there are free tools available to convert your data into 8-bit image files for rendering using Voxx. Screen images can be saved in TIFF, PNG, or raw file formats, and movies can also be stored in uncompressed AVI files.
 
User Interface
The program does not (yet) use a conventional menu bar. It instead uses context-sensitive (aka pop-up) menus and 2-3 button mice. Clicking the right button on the mouse while the cursor is in a Voxx window will display the relevant menu. Mac users must hold the Control key down when clicking the button on an Apple mouse to emulate the right button, or buy a Mac-compatible 2-3 button mouse. Dialog boxes generally behave as expected, except for the File Open dialog (due to the need to sometimes load several files representing multiple channels and/or multiple time points)
