How to sample a 3D raster along a 3D path (or 4D raster along 4D path)?

[المشرف العام]

I have a 3d raster dataset of atmospheric variables (lat x lon x altitude). I would like to sample this raster dataset along a 3d path.

Any idea how I can achieve this, preferable with qgis or postgis or rasdaman?

Edit: Actually, my data is 4d (time x lat x lon x altitude), but having a 3d solution would already be great.
