The viral envelope is based on EMDB-1403.  The contour level was set to 3 in ChimeraX.  The model was remeshed in Pixelogic ZBrush, where a sphere was fitted to the membrane surface and all but the surface projections were deleted.

An illustration of the life cycle from PathogenAR is included, with the step associated with this model highlighted.

This model accompanies the  Hepatitis B: The Hepatitis B Life Cycle module in PathogenAR (https://www.niaid.nih.gov/research/pathogenar-mobile-app)
