This tag allows one to specify the direction that a camera is pointing toward.
Values
The possible values are similar to the "Angles and cardinal directions" values for the direction=* key:
| Value | Description |
|---|---|
| <number> | The given number specifies the heading in degrees from 0 to 359 for which direction the camera faces, where 0 is equal to northward, using clockwise rotation. |
| <abbreviation> | One of the cardinal directions, ordinal directions, or secondary intercardinal directions, specified as its abbreviation using uppercase characters [NWSE], e.g. NE means north-east. See the image below for all possible values and their meaning.
|
| <value>-<value> | Two of the above values, separated by a hyphen, indicates a range that the camera may turn. The sense of rotation is always clockwise. That is, 90-270 or E-W means that the camera can turn to view anything in a 180 degree span covering the south, between pointing east and pointing west, but could not point to the north. Whereas 270-90 or W-E would mean that the camera can turn to view anything to the north between east and west, but could not point to the south. The values 0-359 and 0-360 both mean the same thing: that the camera can point in any direction.
|
A single number or abbreviation may only indicate a typical direction for the camera points in. That is, while a camera marked as camera:type=fixed will likely always have a single value, cameras which are camera:type=panning or camera:type=dome might have either a single value for a typical direction (with the full range of motion not specified), instead of a range that indicates the full set of possible directions that it could be pointing.
Examples
| Value | Meaning |
|---|---|
| 45 | Camera typically points toward the northeast. |
| NE | Camera typically points toward the northeast. |
| WSW | Camera typically points toward the west-southwest. |
| 315-45 | Camera can point anywhere in a 90° span centered on north, that is, between northwest and northeast. |
| NW-45 | Camera can point anywhere in a 90° span centered on north, that is, between northwest and northeast. |
| 45-315 | Camera can point anywhere in a 270° span centered on south, that is, anywhere between northeast and northwest (including east, south, or west), but cannot point north. |
| 0-359 | Camera can point in any direction. |
| 0-360 | Camera can point in any direction. |
