Top View

Top View (during cross-eye stereo use)

In the Side View, setting View to top shows the relationship between the viewer and the Chimera scene from the top. This Top View allows perspective and stereo parameters to be adjusted interactively. These and additional related parameters can be changed numerically in the Camera tool.

• The horizontal field of view is the angle formed by the lines emanating from the eye position when perspective is being used. This angle can be adjusted by dragging one of the red lines with the left mouse button or dragging the eye position horizontally with the middle mouse button. the eye position vertically with the middle mouse button.
  
  
• When stereo is on, the eye separation can be adjusted by dragging the eye position vertically with the middle mouse button.
  
  
• The vertical dashed line represents the plane of the screen (the so-called focal plane). When viewed in stereo, objects in front of the focal plane will appear to project from the screen and objects behind it will appear to recede behind the screen. Dragging the dashed line with the left mouse button moves the focal plane relative to the objects in view. At the same time, the eye position will adjust (changing the apparent scale) to keep the distance to screen constant.

The scale, camera mode, and global clipping planes can be adjusted just as in the standard Side View.
