Spacial Events Plugin for krpano

This plugin enriches your hotspots with some extra events and properties, and provides some extra useful krpano actions related to the spacial environment.

Online demo: https://krpano.kri-soft.be/spacial/

Do something when (not) looking at hotspots

<hotspot name="myhotspot" lookatrange="30" onlookat="dosomething()" onlookout="dosomethingelse()" />

Where:

lookatrange: the angle on when the actions should be triggered (value: 0-180)

onlookat: action to execute when view enters the range

onlookout: action to execute when the view leaves the range

Do something when the hotspot becomes (not) visible

<hotspot name="myhotspot" hittest="true" onvisiblein="dosomething()" onvisibleout="dosomethingelse()" />

Where:

hittest: perform hittesting for this hotspot (true/false)

onvisiblein: action to execute when hotspot becomes visible from the current camera view (not blocked by 3D geometry)

onvisibleout: action to execute when the hotspot becomes invisible from the current view (blocked by 3D geometry)

Do something when you get far/close to a hotspot

<hotspot geofencedistance="750" ongeofencein="dosomething()" ongeofenceout="dosomethingelse()" />

geofencedistance: the distance to the camera

ongeofencein: the action to execute when the viewer is entering the geofencedistance from the hotspot

ongeofenceout: the action to execute when the viewer is leaving the geofencedistance from the hotspot

Additional properties available for the hotspot:

When lookatrange > 0, these are set:

• hotspot[name].lookstate: 0/1: 0: the hotspot is currently not in range of the view, 1=the hotspot is currently in range of the view
• hotspot[name].anglefromcam: the current angle for the hotspot as seen from the camera (0-180)

When hittest is true, these are set:

• hotspot[name].inview: 0/1: 0=the hotspot is currently not visible, 1=the hotspot is currently visible

when geofencedistance > 0, these are set:

• hotspot[name].geofencestate: 0/1: 0 = the viewer is currently not within the geofence, 1 = the viewer is currently within the geofence
• hotspot[name].distancefromcam: distance between viewer and the hotspot

Extra actions available in krpano:

• getdistancebetweenpoints(x1, y1, z1, x2, y2, z2): calculates the distance between 2 given pointsusage example:set(distance, calc(getdistancebetweenpoints(x1, y1, z1, x2, y2, z2)));
