operations to manipulate the camera position, view direction and
orientation in the scene.

AllowRotationOverConstrainedUpAxis |
When true, the viewer can rotate over the
constrained up axis. For example, the viewer is able to flip over
the North Pole and view the globe upside down.
|
|
|
Axes |
The camera's axes of rotation.
|
|
|
ConstrainedUpAxis |
Constrain the up vector to the plane the
vector is in.
|
|
|
FarNearPlaneRatio |
The ratio of the far plane distance to the
near plane distance for a frustum. Multiple frustums will be used
for rendering based on the near and far plane distances, as well as
this ratio. A lower far to near ratio will result in better z
buffer precision bu???
|
|
|
FarPlane |
The distance, in meters, from the viewer to
the far plane.
|
|
|
FieldOfView |
The field of view, in radians, in the screen's
y axis. The default is 35 degrees. Wide fields of view create
bigger view frustums, with more potentially visible objects but can
look distorted.
|
|
GetDirection(IAgGxAxes) |
Returns a normalized vector representing the
direction the camera is looking, defined in the requested
axes.
|
|
|
GetPosition(IAgGxReferenceFrame) |
Returns the position of the viewer, in the
requested reference frame.
|
|
|
GetUp(IAgGxAxes) |
Returns the normalized up vector representing
the orientation of the camera, defined in the requested axes.
|
|
|
LockViewDirection |
When true, the viewer can only zoom in and
out. That is, only the viewer's position can change, not direction
or up vectors. If ConstrainedUpAxis is ConstrainedUpAxisNone, the
viewer can also twist, which changes the up vector.
|
|
|
Move(IAgGxConstantCartesian) |
Translates the viewer's position by the
specified offset.
|
|
|
NearPlane |
The distance, in meters, from the viewer to
the near plane.
|
|
|
SetDirection(IAgGxConstantCartesian) |
Modifies the direction the viewer is looking
by setting it to the specified direction.
|
|
|
SetNearFarPlanes(Double, Double) |
Sets the distance, in meters, from the viewer
to the near and far planes.
|
|
|
SetPosition(IAgGxConstantCartesian) |
Modifies the viewer?s position and explicitly
sets it to the specified postion.
|
|
|
SetPositionAzimuthElevation(Double, Double) |
Modifies the viewer's position using azimuth
and elevation angles. Azimuth is an angle from the positive x axis,
to rotate around z. Elevation is an angle to rotate from the xy
plane toward z. This is commonly called after ViewExtent.
|
|
|
SetPositionRadius(Double) |
Modifies the viewer's position so a sphere of
the specified radius at the current reference point is completely
within the view frustum. This is commonly called after View or
ViewDirection to move the viewer back so an entire object is
visible.
|
|
|
SetUp(IAgGxConstantCartesian) |
Modifies the up vector of the viewer to the
sprecified direction. This won't do anything unless
ConstrainedUpAxis is set to None.
|
|
|
Snapshot |
Provides functionality for taking snapshots
from the camera.
|
|
|
Speed |
The zooming speed in meters per second, if the
camera is in untethered mode. Otherwise, the speed is zero.
|
|
|
Update () () () |
Clears any cached values for axes, points or
vectors that are used in the current camera view. This should be
called if the underlying objects are changed.
|
|
|
VideoRecording |
Provides functionality for recording and
taking snapshots from the camera.
|
|
|
View(IAgGxPoint, IAgGxPoint, IAgGxConstantCartesian, IAgGxAxes) |
Views from a point to a point. Sets the
viewer's position and the reference point the viewer is looking
at.
|
|
|
ViewCentralBody(IAgGxCentralBody, IAgGxAxes) |
Zooms to a central body and use the specified
axes for rotation. The reference point is set to the center of the
central body and the viewer's position is set so the entire central
body is visible.
|
|
|
ViewDirection(IAgGxPoint, IAgGxVector, IAgGxConstantCartesian, IAgGxAxes) |
Views from a point to a direction. Sets the
viewer's position and the direction vector indicating where the
viewer is looking.
|
|
|
ViewExtent(IAgGxCentralBody, Double, Double, Double, Double) |
Zooms to a rectangular extent on the globe.
The camera will be looking straight down at the extent, with the up
vector pointing toward local north. The axes of rotation is an
east-north-up axes.
|
|
|
ViewExtentUsingExtent(IAgGxCentralBody, IAgGxConstantExtent) |
Zooms to a rectangular extent on the globe.
The camera will be looking straight down at the extent, with the up
vector pointing toward local north. The axes of rotation is an
east-north-up axes.
|
|
|
ViewMode |
Returns the view mode. ViewModeNormal is
returned unless the camera was put into untethered mode by calling
ViewUntethered.
|
|
|
ViewOffset(IAgGxPoint, IAgGxConstantCartesian, IAgGxConstantCartesian, IAgGxAxes) |
Sets the camera's reference point ? the point
the viewer is looking at. The viewer's position is the reference
point translated by the offset.
|
|
|
ViewOffsetDirection(IAgGxPoint, IAgGxVector, IAgGxConstantCartesian, IAgGxAxes) |
Sets the camera's reference point ? the point
the viewer is looking at. The viewer's position is the reference
point translated by the direction vector.
|
|
|
ViewUntethered(IAgGxPoint, IAgGxVector, IAgGxConstantCartesian, IAgGxAxes, Double) |
Sets the view to untethered, which allows the
viewer to move freely in space. Sets the viewer's position and
initial direction they are looking. Zooming speed is in meters per
second.
