Shadow Projection - Zeiss Lightsheet Z.1 Operating Manual

Carl Zeiss Center Screen Area / Image Containers - Display and Image Analysis
Series:
3D Data can be visualized online by simply grabbing and turning the data stack with the mouse. In
addition to this interactive way of interacting with the data, 3D VisArt is able to perform render series
where the dataset is turned around one of the axes, along a freely defined position list, or a freely
definable start and end point. The resulting series can be saved as movie files for presentations. A
preview of the render series is available in the position list mode.
Measurements:
Measurements of distances, angles, and polylines can be measured using the Measure panel in 3D VisArt.
Settings:
In the Settings panel, global settings for the 3D VisArt Module can be found.

CHAPTER 4 - SYSTEM OPERATION
4.8.1
In the Shadow render mode (Fig. 305), the
structures in the image are illuminated by a virtual
light source.
The volume is viewed as if looking through the
eyepieces of the microscope and the light source
projects a shadow onto a background plane.
This gives the data a reference in space, making
visualization much easier. The rendering effect
itself consists of a combination of light reflection
and opacity (degree of transparency).
The display in this mode is calculated by the main
processor (CPU) of the computer (Voxel mode).
The different modes can be accessed by clicking on
the pull down symbol at the right hand side of the
Shadow button (Fig. 306).

With a click on Front, the 3D reconstructed image
is displayed in a shadow projection where it is
illuminated at a 45° angle from the front left.
A click on the Back button creates the same
projection with illumination from the back left.
Detailed settings for shadow projection can be
accessed via the Appearance tab.
