Light Tab

Brightness

Sets the brightness of the light source (from 0 - 100 %).

Azimuth

Here you can enter the angle of the light source above the virtual horizon.

Elongation

Here you can enter the light source's horizontal angle of incidence.

Light source

As an alternative to the slider or input field, you can set the Azimuth and Elongation together by using the mouse to move the point within the light source display.

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.

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.

Reset

Resets all parameters to the original values.
