Decreasing the ViewFieldAngle creates the appearance of zooming in even though the observer position is unchanged.

The default ViewFieldAngle is 55 degrees.

                           AutomationException

The roll angle in degrees.

Remarks

The RollAngle represents the angle, in degrees, of the camera about the line of sight between the observer and target. Angles will be reported in the range >=0 and <360. Angles can be given outside of this range but will be 'wrapped' to the equivalent value in the 0 to 360 range. For example -1 is the equivalent of 359 and 361 is the equivalent of 1.

A RollAngle of 0.0, the default, is straight up relative to the Z axis in the scene. Increasing the RollAngle will tilt the camera clockwise about the line of sight.

                        AutomationException

Indicates if the camera has valid parameters.

Remarks

Before doing something with a camera it is advisable to call IsUsable first. It's possible the camera has some properties which are undefined or is unable to perform certain requests. This happens when a camera is associated with an empty scene, the target/observer or other parameters has invalid values (not a number, for instance), or when the target and the observer share the same location etc.

                             AutomationException

The polar inclination of the observer relative to the target. When changed, the observer moves.

Remarks

The inclination represents the altitude angle, in degrees, of the observer relative to the target. When the observer is above the target the inclination is positive, when below it's negative.

The value given for inclination can be greater than -90 or less than 90. Values outside this range will be reset automatically to the closest positive or negative limit (e.g. 95 reset to 89.9999).

                         AutomationException

The polar azimuth of the observer relative to the target. When changed, the observer moves.

Remarks

The azimuth represents the compass direction, in degrees, of the observer relative to the target. At 0 degrees the observer is due north of the target, 90 degrees due east, 180 degrees due south, and 270 degrees due west.

Values exceeding the range 0-360 will be reset to the equivalent value that falls in this range (e.g. 365 gets reset to 5, -5 gets reset to 355).

                 throws IOException,
                        AutomationException

Updates the observer's location by given polar increments.

Remarks

The observer will be moved by the values specified in the arguments:

The distanceFactor resets the current ViewingDistance (distance between observer and target) by multiplying it by the given factor.

dAzimuth is added to the current azimuth.

dInclination is added to the current inclination. If the resulting inclination doesn't fall between -89.9 and 89.9 it will be reset so that it does unless bLimitInclination is set to False.

bLimitInclination when set to True ensures the modified inclination doesn't fall outside the -89.9 to 89.9 limit. If set to False and the limit is exceeded the azimuth will be changed 180 degrees and the UpDirection will be flipped.

The state of multi-phase rendering. When true, the scene depth can be divided into multiple passes to improve rendering quality.

Remarks

MultiPhaseRendering is only implemented in ArcScene. When set to True (the default is False), multiple drawing steps are enabled to avoid Z-buffer imprecisions when the ratio of far/near distance is too large, therefore layers with extreme extents may be seen throughout the scene. The far/near distance here refers to the distance between the observer and the far/near clipping plane in OpenGL terms.
