Setup Appearance

Setup Appearance Window

The setup appearance window is opened by clicking the appearance button located along the bottom of the Setup window. In this window you can customize the appearance of the model and adjust the opacity settings for many of the components of the 3D model.

Ocular anatomy group

The buttons of this group switch between 3D surface and edge (ie wireframe) rendering.

Edges - Only the edges of the triangles that
form the surface of the eye will be rendered.
This is also known as 'wireframe' mode.
Surface - The triangles that form the surface
of the eye will be rendered as a solid surface
according to the selection below:

Translucent - The eye will be rendered
translucently.
Opaque - The eye will be opaque.

Edges (wireframe)

Translucent

Opaque

Other objects group

The menus and buttons of this group modify the appearance of the Setup window in ways which may be of interest when preparing figures for publication and/or screen captures for educational purposes.

Plaque - selects the 3D rendering method of the plaque.
Slots - selects the 3D rendering method of the slots in a plaque.
Sources - selects the 3D rendering method of the radionuclide sources.
Placeholders - selects the 3D rendering method of the source placeholders. Options include as a cylinder or as lines with pen widths of 1, 3 or 5 pixels. The placeholder cylinder width is a slot editor parameter. Lines and 2D projections are slightly faster to draw on less powerful cpus, while cylinders are sometimes easier to see.
Retinal dose - provides additional control over rendering of dose to the retinal surface.
3D dose - provides additional options for 3D rendering of isodose surfaces.
Autoradiograph - provides additional options for rendering of simulated autoradiographs.
Tumor - provides additional options regarding the shape and appearance of the tumor.

Show tumor margin - plots the PTV expansion margin (e.g. 2mm) around the tumor base.
Show 3D bounds - renders each plaque's 3D bounding box for 3D dosimetry.
Show 3D matrix - renders each plaque's 3D dose matrix.
Show pseudo color margin - plots the pseudo coloring margin surrounding the tumor base for spheroidal surface reconstructions.
Diagram meridians - plots meridian lines on the retinal and ciliary surface with tick marks corresponding to the meridians found in the retinal diagrams.
- 1 mm - Tick marks are spaced at 1 mm of arc increments working posteriorly from the limbus.
- 5 deg - Tick marks are spaced at 5 degree increments of lattitude from the equator.
- Posterior range - In the anterior hemisphere (or hemi oblate spheroid) meridians lines are plotted from the limbus to the equator. In the posterior hemisphere, the meridians are plotted from the equator over the specified range of lattitude. The default is to plot the meridians between the equator and 60 degrees posterior lattitude.

e.g. tissue voxels for lens, tumor and anterior chamber.

Voxels group

Show voxels - Displays the voxels associated with certain anatomic regions of the 3D model. These voxels are used to approximate volumes and ray trace distances across tissues with differing physical properties such as density and effective atomic number.

Cornea - Cornea (approximates the anterior chamber).
Lens - Lens.
Vitreous - Vitreous humor.
Sclera - Scleral shell.
Tumor - Tumor "GTV".
Nerve - First few mm of optic nerve and sheath.
Muscles - Muscle attachments.
Air - Air in front of eye.

Voxel dimensions - The voxel dimensions default to 0.4 x 0.4 x 0.4 mm cubes covering a volume of 40 x 40 x 40 mm surrounding the eye origin. The voxel dimensions can be customized here using the popup menu and/or as a preference setting in the Model Preferences Eye controls group.

Planar surfaces group

Meridian plane - shows the meridian CT image.
Coronal plane - shows the coronal CT image
Axial plane - shows the axial CT image.
Equatorial plane - shows the equatorial CT image.
Sagittal plane - shows the sagittal CT image.
Nerve plane - shows the nerve (coronal) CT image.
Misc. plane - shows the user customizable plane and its CT image.
Autoradiograph plane - shows the autoradiograph plane.
Miscellaneous plane - shows the miscellaneous plane (meridian with offset from eye center).
Use MPR for miscellaneous - reconstructs the miscellaneous plane from CT if available.
Air plane - shows the air-tissue boundry plane.
Ora plane - shows a cornal plane through the ora-serrata.
Sliders - the sliders adjacent to each plane's enabling checkbox determine the displayed range in mm of the reconstructions.

Labels group

Some labels are rendered statically, their orientation is fixed with respect to an object in the scene, such as the plaque. Most labels are billboarded, their orientation always faces the viewer.

Eyelets - adds static labels to the plaque eyelets.
POI - adds labels to points of interest.
Profiles - adds labels to profile lines.
Muscles - adds labels to the muscle insertion markers.
Ru meas. - adds static labels to the BEBIG measurement points.
Ru anneal - adds static labels to the BEBIG surface annealing points.
Reverse - reverses the orientation of static labels such as plaque eyelet labels.
Optic nerve - displays additional optic nerve dosimetry points and dose.

Suture guidance group

Show - plots meridian lines and chords illustrating the suture eyelet guidance coordinates.

AL - Chord from eyelet A to the limbus.
AM - Meridian through eyelet A.
AB - Chord from eyelet A to eyelet B.
BL - Chord from eyelet B to the limbus.
BM - Meridian through eyelet B.

e.g. opaque plaque, translucent sources and tumor, suture guidance meridians and chords enabled.

Points group

Ru measurement - plots the BEBIG surface measurement points.
Ru annealing - plots the BEBIG surface annealing points.
Rx point distance - draws a vector from nearby inner sclera to the Rx point.

Spheroidal surfaces group

Reconstruction - texture the spheroidal reconstruction surface.
Transparency - makes black in the reconstruction transparent and enables cutplanes.
- Left - hides spheroidal reconstruction to the left of the horizontal cutplane. The cutplane location is expressed as a percentage of the image width or height.
- Right - hides spheroidal reconstruction to the right of the horizontal cutplane.
- Above - hides spheroidal reconstruction above the vertical cutplane.
- Below - hides spheroidal reconstruction below the vertical cutplane.
Fundus - texture the retinal surface with the fundus imaging.
Transparency - makes one color (by default black) of the fundus imaging transparent and enables cutplanes.
- Left - hides fundus to the left of the horizontal cutplane. The cutplane location is expressed as a percentage of the fundus image width or height.
- Right - hides fundus to the right of the horizontal cutplane.
- Above - hides fundus above the vertical cutplane.
- Below - hides fundus below the vertical cutplane.
Iris - texture the iris surface.

Sliders - the sliders adjacent to each plane's enabling checkbox determine how much of the CT image surrounding the eye is displayed.
