Tracking Scans (HoloLens Spatial Mesh)
The Track Scan component outputs the HoloLens Spatial Mesh data as a list of meshes that you can use in your parametric model. You can use the Request button on the component to request this data from the headset, or parametrically request the spatial mesh using the Prompt input. There is often a short delay between requesting the spatial mesh data and receiving it in Grasshopper as meshes can be very large (>100mb).
The HoloLens builds the spatial mesh using the long range depth data on the Headset and will update the geometry every few seconds. For this reason it is uncommon to need to request Spatial Mesh data at a high frequency (unlike tracking device or hand positions).
