Step 1: Load
|
BioVis3D supports all standard image file formats. These images can be obtained from a digital camara attached
to a microscope or from a tomograph.
BioVis3D supports loading images with different resolution within the same model in case you need to focus on a
specific area of interest with higher detail.
BioVis3D also includes a mosaic feature that allows you to use compound images comprised by several independent
images adjacent to each other.
Once loaded, each image can then be viewed and manipulated independently to create an accurate 3D model.

Step 2: Align
|
In general, due to the acquisition process, it may be necessary to correct small displacements among slices.
BioVis3D offers the necessary tools to align sections spatially. Slices can be translated, rotated and made
semi-transparent to help with this registration process.
Object contours may remain visible during slice movement to make this task easier and, once again, all these tools
can be used with an appropriate zoom factor. The images of the sequence may be taken with different resolutions.
BioVis3D handles multi-resolution images and shows a consistent view of the slices to the end user.

Step 3: Contour
|
The objects of interest can be detected with a simple semi-automatic procedure.
The object is roughly delimited by the user and BioVis3D detects the exact contour
applying a refinement algorithm.
The resulting contour can always be edited by the user if the final result must be adjusted.
Both the automatic detection and the manual contour edition tools work with any zoom factor to adjust to the appropriate level of
detail.

Step 4: Go 3D
|
Once the slices are aligned and the object contours are detected, the object of interest is ready to be built and
visualized.
These objects are presented in a 3D scene where objects can be shown and hidden individually or by
categories.
All morphological details can be appreciated moving objects spatially, making some objects semi-transparent, and
cutting a whole scene.
All scenes are exportable to standard formats that can be included as pictures or videos in
publications, congress presentations and web pages.
