bone_octahedral_smooth_normals

static

Initial value:

    {float(M_SQRT1_2), 0.0f, float(M_SQRT1_2)},

NOTE: This is not the correct normals. The correct smooth normals for the equator vertices should be {+-0.943608f * M_SQRT1_2, -0.331048f, +-0.943608f * M_SQRT1_2} but it creates problems for outlines when bones are scaled.

Example: triangle {2, 1, 0} is adjacent to {3, 2, 0}, {1, 4, 0} and {5, 1, 2}. {2, 1, 0} becomes {0, 1, 2} {3, 2, 0} becomes {3, 4, 5} {1, 4, 0} becomes {9, 10, 11} {5, 1, 2} becomes {12, 13, 14} According to opengl specification it becomes (starting from the first vertex of the first face aka. vertex 2): {0, 12, 1, 10, 2, 3}
