 3VO - the
new viewer for Slicer Dicer
The new viewer for Slicer Dicer, 3VO, is a
major improvement provided by Slicer Dicer v5. Click on either of the
links below to view a simple flash tutorial that provides a brief description
of 3VO.
Low Resolution
(600 pixels across)
High
Resolution (900 pixels across)
Here are some of the features available in
the 3VO window:
 |
Realistic 3D projection - precise control
over camera field-of-view and
distance. |
|
Interactive zoom - drag the cursor to
increase or decrease the scale. |
|
Virtual-trackball interactive rotation -
drag the cursor to rotate and/or
spin the scene. |
|
Multiple lights - ambient plus any number
of directional lights. |
|
Realistic surface light-reflection model
- adjust diffuse and specular
reflection coefficients for individual surfaces. |
|
Surface representation options - points,
wireframe, or solid. |
|
Translucent surfaces - set opacity
for any surface from 0% to 100%. |
|
Export 3D model data to a file - 3ds,
cob, dxf, pov, and other formats
are supported. |
The last feature in this list, 3D model
data export, is distinct from the others in that it is unrelated to
interactive viewing. You can use this feature to export your scene to a
file in any of several standard formats that are used in the 3D modeling
industry. This makes it possible to extract 3D objects from your data set
and merge them into other modeling environments. For example, the exported
model-data file could be read by a stereolithography machine, or other
rapid prototyping device, to produce a physical replica of a structure of
interest extracted from your data.
NetCDF Large File Support
| NetCDF "Large File Support" (LFS) is now
included in Slicer Dicer. Previous versions were linked to v3.4 of the
netCDF libraries from Unidata (UCAR). This version is linked with
netCDF v3.6, which adds LFS.
The following is quoted from the FAQ
entitled "What is Large File Support?" on the Unidata web site
(http://my.unidata.ucar.edu):
"Large File Support (LFS) refers to operating system and C library
facilities to support files larger than 2 GiB. On many 32-bit
platforms the default size of a file offset is still a 4-byte signed
integer, which limits the maximum size of a file to 2 GiB. Using LFS
interfaces and the 64-bit file offset type, the maximum size of a file
may be as large as 2**63 bytes, or 8 EiB. For many current platforms,
large file macros or appropriate compiler flags have to be set to
build a library with support for large files. This is handled
automatically in netCDF 3.6."
NetCDF datasets with LFS can be created on 32-bit Windows platforms
(using netCDF v3.6). Now, both LFS and, older,
non-LFS netCDF files can be successfully opened.
