Attributes

• rotatepace

  Specifies the amount of pan/tilt rotation relative to the mouse movement, as well as the rotate speed when pressing the cursor keys. Higher values make the panorama spin faster with less mouse movement.
  Values: sensible .01 - 2, defaults to .6

• rotateinertia

  Specifies how the camera's pan/tilt inertia: a measure of how fast the camera rotation speed decays after the mouse is released. If paninertia is set to 0, the camera stops panning immediately when the mouse is released. A value of 1 means that the camera continues rotating in the current speed and direction indefinately.
  Values: 0.0 to 1.0, defaults to 0.8

• zoompace

  Specifies how fast the camera zooms in out when the zoom keys are pressed, or when zooming using the right mouse button. Higher values make the camera zoom faster.
  Values: sensible 0.1 - 2, defaults to 1

• zoominertia

  Equivalent to rotateinertia for zoom.
  Values: 0.0 to 1.0

• panroll

  Slightly rolls the camera when panning around the scene.
  Values: -1.0 to 1.0, defaults to 0

History

• 19-May-09: Added panroll, which has been an undocumented feature since version 1.0
• 12-Feb-08: Changed zoomspeed to zoompace and rotatespeed to rotatepace to reflect changes in SPi-V 1.4.5
• 16-Oct-04: Updated default values
• 07-Apr-04: Initial version
