Fig. 9

A tractography dataset with a group of segmented bundles (Dataset II), displayed with different visualization and illumination settings. The “Display Settings Bar” is also displayed at the bottom of the screen. A Line display with only ambient illumination (\(A=1\), \(D=0\), \(S=0\)). B Line rendering with high ambient, diffuse and specular illumination (\(A=0.8\), \(D=0.9\), \(S=14\)). C Cylinder rendering with a non-zero material reflection coefficient for ambient illumination (\(Ka=1\), \(Kd=0\), \(Ks=0\)), resulting in only an ambient light component. D Cylinder display with high ambient, diffuse and specular illumination (\(A=1\), \(D=0.9\), \(S=0.95\))
