Node weights in path calculation

August 21, 2015

We have updated path finding functionality and path calculation. Now it is possible to change the weights of navigation nodes in 3D Wayfinder floor plan editor.

Path-finding application calculates automatically the shortest route from the starting node to the required location. In mobile applications, the Kiosk node can be your position inside the building. With 3D Wayfinder, the shortest route is calculated in a 3 dimensional room, which means the shortest path through all the floors.

Now it is possible to change the weights of the connection nodes. With this way finding application calculates optimal route, which doesn’t have to be the shortest. For example when you would like to guide your visitors to use the path inside the building instead of going around the building, you can set the weight for outdoor nodes higher. The weight is basically virtual length that will be added to the route, when passing the navigation node with a weight.

To use the weights you have to select the navigation node in 3D Wayfinder floor plan editor and change the node weight from the text box. By default all the weights are 0.

For example lets, say that waiting for the elevator takes usually 3 minutes. Lets assume, that visitors are moving with a speed of 3 km per hour, which is 50 meters per minute. So with waiting the elevator, visitor can pass 150 meters (3*50). If we would like to take account this in path calculation, we can add weight of 150 to the navigation node, that is marked as elevator.

Pathfinding functionality comes bundled in an add-on you can order from 3D Wayfinder Administration panel. It is also included in the Pro plan.
