An example of LIC on a plane embedded in 3D shows figure2.31 on page 31. To explain why LIC is so successful and why so many papers havebeen published on LIC is, that it generates images easy to perceive and very similar tothe images from physics classes at school.• Pseudo – LIC (PLIC) [VVP99]One of the most important extension to LIC [CL93] is PLIC [VVP99]. The authorclosed the gap between LIC and stream line drawing algorithms. The resultsfrom PLIC mapped onto 4 wheels of an aeroplane landing gear are also shown infigure 2.31. This algorithm uses one unique 1D texture for each streamline andspeeds up LIC.Figure 2.30: LIC in 3D with cutting planes and regions of interest [CRE99].30
