hello people, i'm a 3d modeler and animator, and i have a question regarding triangles. this is a polyomavirus, http://www.brown.edu/Research/Atwood_Lab/assets/images/home/SV40_particle.jpg it has a icosahedral geometry and 72 capsomeres (the flower things) arranged on its triangles, like this picture: if i pick a triangle, i can see that it has one capsomere in each vertex and three arranged inside the polygon. my question is how to properly arrange these 3 capsomeres in each triangle. if you take a closer look at the picture, you'll notice that each vertex' capsomere has 5 others capsomeres around it, and the other capsomeres (those arranged inside the triangles) have 6 others. they have to be distanced equally from all the capsomeres surrounding them. thank you in advance!
