Render Settings
You can change the way a Render view looks by adjusting the settings under Render
Settings on the left side of the screen (see Fig 20-15):
•
Opacity – Specifies the transparency of a structure.
•
Thickness – Determines how far you can look into the volume.
•
Filter – Sets a threshold so that pixels that are not as bright as the threshold are
not displayed.
•
Luminance – Controls the brightness of structures within the volume. Moving
the slider to the left increases brightness.
•
Photorealistic – Adjusts the photorealistic parameter used in the rendering.
This can only be used on gray scale volumes.
Sculpting Tools
Sculpting tools let you remove unwanted data from a Render view. Sculpting tools
can only be used on gray scale volumes – when there is no color in the volume.
There are two sculpting tools:
•
the cutting tool (which you can use to cut away the outside of the volume or to
cut a hole inside the volume)
•
the shaving tool
To use the sculpting tools:
1 Click Remove under Sculpture on the right side of the screen.
2
Click to select Inside, Outside or Shave.
3
If you select Inside, you can adjust how deep you want to cut. Click Depth
under Sculpture and move the slider to adjust the percentage that is removed
when you move the cutting tool.
4 Use the different tools as described below.
When you select a sculpting tool, the cursor
on the screen changes, to a cutting tool icon
or a shaving tool icon.
