6.9.12 Options
XY Textures only : Instead of working with three
texture stacks per dataset in transparent render
mode, the system will only use one texture stack.
This will result in faster renderings. Looking at the
dataset from aside although will make the
individual z-planes visible.
Inner surface lighting
: If checked, illuminates the
inside of a surface rendered volume. If unchecked,
the inside is dark. If one views the inside of a
volume by flying or zooming into it, the inside
illumination is helpful. This option is only available
for the
Surface
mode.
Lit front and back side : With activated Inner surface lighting , this check box colors the inside lighting
with a bluish hue. This makes distinguishing inside from outside easier. This option is only available for
the
Surface mode.
Draw border triangles
: When displaying the data touching the six sides ("borders") of the Z-Stack in
3D, the triangles used to do this are all located in one plane and orientation. This can cause artifacts,
therefore the display of those border triangles can be switched off.
Texture switch angle : This parameter influences the volume angle, upon which the next set of 2D-
Textures will be loaded into the graphics card (value range 1 to 100 degree). Depending on the object
orientation, the number of z-slices and the chosen render settings this loading process can be visible and
may be disturbing especially when rendering a series for movie export. Changing this angle can postpone
or even avoid this switch during a series rendering. This option is only available for
Transparency and
Maximum modes.
Image Rotation with mouse
: Activates a method to rotate the dataset interactively with the mouse. In
addition to rotating it freely, when clicking and dragging at the sides of the image window the dragging
rotates the data around one axis only. Just like the wheels on the 3D window frame.
Mouse Sensitivity
: Influences the mouse sensitivity (value range: 1 to 200). Small values make the
mouse actions precise but slow, large values less precise but faster.
Texture Opacity : With this slider the
α
-values of the dataset can be adjusted. The rendering is getting
more or less transparent using this setting.
Reset : Sets all render settings back to the factory standard settings.
Renderer Options:
Renderer
: OpenGL Software is rendering the 3D
data with the CPU; OpenGL Hardware uses the
Graphics card to do this. Especially when having
trouble with non Zeiss-certified graphics cards it is
sometimes useful to switch to a pure CPU based
rendering.
Palette textures : This feature is an optimization
feature not supported by modern graphics cards
any more. It used to optimize display of single
channel images.
