Cone-spiked sphere ressembling a simplified Coronavirus shape
A detailed nanostructural model of the Coronavirus is illustrated here (static)
or here (animated)
. Realistic nanostructural size dimensions are: total diameter ~ 100 nm, length of the (approximately 100 per virion) spike-proteins (trimers) ~ 10 nm. Calculating the RG and V for the default model (rr=200, rc=10, rl=100, rs=20 and with the resulting distance of the center of gravity of the 18 inverted cones to the center of the sphere being 200 + 3/4*100 = 275, and of the 18 spike-spheres to the center being 200 + 100 + 20 = 320) these parameters are entered as input in the Rg-Calculator for composed solid shapes
as shown below.
