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)
