Step2: Move a viewpoint
Output of the sample program
Move a viewpoint from the center of anterior/vental side of the body
horizontally and vertically around a focal point by 45 degrees, respectively.
The focal point is the center of the body.
Explanation of the sample code
See also Javadoc for details of each methods.
line 18-22： Set a viewpoint, which consists of a reference point and offsets from it along horizontal/longitude and vertical/latitude direction in degrees, respectively.

| Reference point of a viewpoint |
Set either front, left, right or back as the rough position of eyes (viewpoint).
The viewpoint is on the equator of the bounding sphere of a whole body or specified organs.
"front" (the anterior/vental side of a human body, (longitude、latitude)=(0,0))
"right" (the right side of the body, (lng, lat)=(90,0))
"back" (the posterior/dorsal side of the body, (lng、lat)=(180,0))
"left" (the left side of the body, (lng、lat)=(270/-90,0)) |
front |
setViewpoint("front") |
| Offset from the reference point (horizontal/longitude) |
Offset from the reference point along the horizontal/longitude direction.
Right/east direction is positive. Unit is degree.

setViewpointOffsetHorizontal(-45) |
| Offset from the reference point (vertical/latitude) |
Offset from the reference point along the vertical/latitude direction.
Upper/north direction is positive. Unit is degree.
