Help with demispherical dome mesh mapping

[arnabiswas]

Hi all, I am new to bonvision and bonsai. I am trying out the mesh mapping guide here https://bonvision.github.io/demos/demos_006_MeshMapping/ we have a similar setup. I am having an issue where I am not able to see the grid once I run the workflow and hence unable to proceed with the calibration.

I am running this workflow https://github.com/bonvision/examples/blob/master/ScreenCalibration/MeshMapping/MeshMapping_generate2023.bonsai

I am using the latest version of bonsai (2.8.5) and bonvision - if that is relevant. When I run the workflow I get a notification that the workflow has been updated to work with the version of bonsai I am using.

I have tried this on multiple PCs and cannot get the grid to display. So I am assuming that it is something basic that I am getting wrong. The guide mentions " If you cannot see the grid, select the visualiser for the DrawGrid node. You may need to restart the workflow/assign the first point before the grid appears." I tried doing this by right clicking on the DrawGrid node and changing the visualizer. It did not help.

Any help with this appreciated! Thank you!
