Basic Usage
Open/Add a dataset
A dataset can be either local or remote (e.g. provided by a ViSUS Server).
Local dataset
Two options are available to open a local dataset in the menu File:
- Open file... (open a single file, all the datasets in the current session will be discarded)
- Add file... (add a dataset to the current session)
Remote dataset
Two options are available to open a remote dataset in the menu File:
- Open URL... (open a remote dataset, all the datasets in the current session will be discarded)
- Add URL... (add a dataset to the current session)
Try, for example, to open the Gigapixel 2D dataset David using this URL: http://atlantis.sci.utah.edu/mod_visus?dataset=david
And zoom in as you like!
Save a scene
The current scene can be saved on disk using the File->Save scene... command. The scene will contain all the datasets and settings in the current session.
The current scene can also be saved as history that will contain also all the operation performed by the user in the scene (i.e. using File->Save history...).
Nodes/Filters
When you open or add a new datasets you will get a tree of nodes on your left sidebar that will allow to define analysis and visualization pipelines.
The default Nodes are the dataset node that provides information about the dataset and the time node that allows to move along the timesteps contained in the datasets.
The main types of Node that the user can add are:
- Slice Node, creates a slice selection of the dataset and related rendering pipeline
- Volume Node, creates a volume rendering pipeline
- Iso Contour Node, creates an isocountour rendering node allowing the possibility to change isovalue interactively
- Scripting Node, allows the user to define execute interactively an analysis code on the input data or use one of the predefined scripts
You can add a Node using the menu Add.
Configuration and Bookmarks
Configuration (i.e. mostly performance and platform specific related) and list of bookmarks (i.e. commonly used datasets) are contained in the ViSUS configuration file.
Collection of IDX datasets
Sometimes can be useful to define a collection of IDX dataset to use for interactive visualization or analysis. MIDX is file format that simply defines a collection of IDX files.
Here are some examples:
