Following our choice of base polyhedron, in this case the icosahedron, the portion of it, in this case the upper half, and the face pattern, in this case a pattern of 16 triangles to each face, we then have a variety of projection variations to choose from. Projection refers to the way in which our choice of now-patterned polyhedron is projected on to a surface, and also to the choice of surface. Here we shall be using projection outwards in all directions away from a chosen point, but we will be looking at projection on to a variety of different surfaces. |
