Aivia Software
Getting Started with IN Carta 3D Viewer
IN Carta uses Aivia to visualize data in 3D. To accommodate, Aivia is launched in a special mode that streamlines the application to features relevant to viewing your data from IN Carta. In this mode, the application is referred to as the “IN Carta 3D Viewer” instead of Aivia.
This page covers the basics of using the 3D Viewer and navigating its user interface. There are links to pages with more detailed information for specific features at the bottom of this page as well.
Navigation Basics
The computer mouse is the primary method for interacting with IN Carta 3D Viewer’s graphical user interface. You can hold down specific keys on your keyboard while clicking with the mouse for additional mouse interactions. Interactions involving the mouse only as well as the mouse and keyboard in combination are summarized in the table below.
Mouse interaction | Keys | Context | Function |
|---|---|---|---|
Left click and drag |
| 3D View | Rotates scene freely |
Scroll wheel click and drag |
| Zooms in or out smoothly | |
Double left click on image |
| Pans to the selected location and sets the location as the pivot point for rotation | |
Double left click on object |
| Zooms to the selected object and sets the center of that object as the pivot point for rotation | |
Right click and drag |
| Spins the camera | |
| Zooms in or out of the scene smoothly | ||
| Rotates the scene about the center of view |

3D View Toolbar
The IN Carta 3D Viewer is always open in 3D viewing mode, and the buttons in the toolbar have been simplified to match.
Name | Icon | Description |
|---|---|---|
Reset View |  | Resets camera position and orientation to the default |
Camera Viewing Axis | | Sets the camera to look at the image along the given axis |
Toggle Volume Bounding Box | | Toggles the display of the white bounding box that surrounds the displayed image |
Toggle Axis Display | | Toggles the display of 3D axes indicating the X, Y and Z directions |
Show FPS | | Toggles the scene frame rate display |
Set Maximum Volume Rendering Quality | | Specifies the maximum volume quality percentage; the default value is 70%, sub-sampling (which is experimental) is used above 100%, and the renderer does not downsample the image volume when the image volume is moved and the maximum quality is above 110% |
Toggle 3D Projection Mode | | Allows you to choose whether parallel planes in the image always appear parallel on the screen (ON) or parallel planes in the image converge/diverge such that objects "farther" from the observer/camera appear smaller than those of the same size that are "closer" (OFF) |
Toggle 3D Filtering Mode | | Toggles the use of interpolation for creating smooth transitions between voxels |
Set Backdrop Color | | Specifies the background color in 3D View |
Toggle Specular Lighting | | Toggles the display of highlights on meshes |
Toggle Dynamic Mesh Level of Detail | | Allows you to choose whether dynamic mesh level of detail (dynamic mesh LOD), where high-LOD meshes are shown for objects that are close to the observer/camera and low-LOD meshes are shown for objects that are far from the observer/camera, is used (ON) or high-LOD meshes are loaded for all objects (OFF) |
Open Mesh Visibility Options |
| Opens a menu of the following options for selectively showing/hiding meshes:
