I am using @napari to visualise images together with RNA molecule. The RNA molecules are visualised by plotting the centroid of the molecules as dots.
Everything has been working fine until we have been scaling up the number of genes, the number of molecules/gene and the sample area.
Napari is able to handle the plotting of the milions of dots but it takes forever and even a computer with decent amount of RAm can only plot a subset of the data.
I was just wondering if you have any suggestion on how we should tackle the issue. Should we somehow use an image-pyramid like approach? Should we load only a subset of dots depending on the level of zoom in?
We have been playing with Datashader before but now napari in an important part of our workflow and we would like to stick to it.
Thanks for the help!
