Here you can define the appearance of the 3D volume. With the reset button on top of the sections of the tab, you can reset the parameters to their default values.

Light

Parameter

Description

Brightness

Sets the brightness of the light source.

Enable Tone Mapping

Activated: Enables tone mapping during the rendering of the image data. Tone mapping refers to the compression of the dynamic range of high contrast images (HDR). The contrast range is reduced in order to display digital HDR images on output devices with a more limited dynamic range. In most cases, tone mapping increases brightness and contrast of the rendering result and makes colors more vibrant.

Enable Directional Light

Activated: Enables full lighting for volumetric rendering. A directional light illuminates all structures in a scene with parallel light rays from a specific direction, similar to sun light. The light disregards the distance between the light itself and the structures, so the light does not diminish with distance.

Azimuth

Only visible if Enable Directional Light is activated.
Sets the angle of the light source above the virtual horizon. Alternatively, you can use the control to the left to set the Azimuth together with Elongation manually.

Elongation

Only visible if Enable Directional Light is activated.
Sets horizontal angle of incidence for the light source. Alternatively, you can use the control to the left to set the Elongation together with Azimuth manually.

Projection

Parameter

Description

View Angle

Adjusts the view angle of the projection.

Scale Z

Adjusts the scaling in z, i.e. the height of the displayed z stack.

Reverse Z-Axis

Activated: Reverses the z axis for displaying the image.
Deactivated: Uses the z axis direction that is automatically detected by the software.
