The Setup window provides a 3D view of the plaque and patient anatomy. The 3D model acts like a "trackball". To rotate the 3D model of the eye simply click anywhere on the eye (except on the plaque) and drag. To position the plaque on the eye, simply click on the plaque and drag. In addition to the buttons in this window, numerous other setup parameters are adjustable from the Eye, View, and Setup menus which appear on the menu bar any time this window is frontmost.

The buttons on the left of the Setup window (from top to bottom) control various setup parameters:

• Eye - selects left or right eye.
• Target - rotates the model for best view of the tumor base.
• Mode - switches between 3D surface and wireframe rendering.
• Translucent - controls the translucency of rendered elements.
• Lock - prevents the plaque from being moved when rotating the eye in "trackball" mode.
• Autotrack - forces the transecting 2D dosimetry surface to move with the plaque.
• Plaque rotation - rotates the plaque around its central axis. The arrows on this control rotate the plaque clockwise or counter clockwise in 1 or 90 deg. increments. You can enter the plaque angle from the keyboard by double clicking on the text field at the center of the control. You can also drag the indicator.
• Plane position - this pair of directional controls immediately below the plaque rotation control adjust the position of the active 2D dosimetry surface selected in the Dosimetry window. The surface can be either a transecting or equatorial plane. The transecting plane rotates around the Anterior-Posterior (AP) axis of the eye. The equatorial plane is perpendicular to the AP axis and can be moved between the two poles.
• Rotate model - this group of six green directional controls rotates the 3D model around the indicated coordinate axis.

The buttons along the bottom of the Setup window (from left to right) adjust the 3D camera:

• Far - moves the 3D camera away from the eye.
• Near - moves the 3D camera towards the eye.

The buttons along the right side of the Setup window (from top to bottom) determine which anatomic and geometric elements are rendered in the 3D model:

• Sclera - Renders scleral surface.
• Retina - Renders retinal surface.
• Cornea - Renders corneal surface.
• Nerve - Renders the optic nerve.
• Lens - Renders the lens.
• Muscle - Renders the approximate locations at which muscles attach to the eye.
• Fundus - Textures the retinal surface using a digitized fundus photo.
• Tumor - Renders the tumor volume.
• LandMk - Renders digitized landmarks such as blood vessels.
• Plaque - Renders the plaque.
• Plane - Renders the current 2D dosimetry surface.
• Points - Renders all point-dose calculation positions.
• Axes - Renders the x,y,z coordinate axes.
• Ret. Dose - Renders dose to the retinal surface.
• 3D Dose - Renders a 3D isodose surface.
