I’m trying to compute geodesic distances between vertices of a surface file using HCP workbench’s command `wb_command -surface-geodesic-distance`

. One part of the related official documentation is as follows (full doc here), but I’m still confused about what to put in the position of `<vertex>`

and `<metric-out> `

? should I specify the index of vertex for `<vertex>`

? (which will be an integer)?

COMPUTE GEODESIC DISTANCE FROM ONE VERTEX TO THE ENTIRE SURFACE

wb_command -surface-geodesic-distance

- the surface to compute on

- the vertex to compute geodesic distance from

- output - the output metric

```
[-naive] - use only neighbors, don't crawl triangles (not recommended)
[-limit] - stop at a certain distance
<limit-mm> - distance in mm to stop at
```
