A slow WiFi network due to an older hotspot or many connections can increase the stream latency (delay). See the Connections section for more help. Another common case of long delays can be very large Rhino or Mesh models.
Optimising Rhino Models
- If you are working with a very large Rhino model (commonly curved by using curve piping, surfaces with high UV counts, or many objects) you may be creating and streaming very large meshes.
- You can control this by manually meshing the geometry you want to stream to the HoloLens. Use the Mesh command in Rhino and experiment with parameter values to create low polygon counts. See instructions below for working with mesh geometry in Fologram.
- If you are streaming mesh geometry in Rhino, you can select the mesh and type the "What" command to display a popup window with the polygon and vertex count. Very large meshes (>500,000 polygons or vertices) can take a long time to send over standard WiFi networks.
- Very large material texture files can also take a long time to send. Go to the Materials window in Rhino and check your textures to ensure you are using small files.
- You may be able to reduce the number of faces and vertices in your mesh without significant losses in detail by using the ReduceMesh command in Rhino. Experiment with different reduction values to find a good balance between detail and polygon count.
