Errata for “Animation of water waves on mesh surfaces”,

Computing in Science & Engineering, vol.8, no.5, pp.81-87, 2006.

In Figure 2(c) (pp.82), the special case for Figure 2(c) should be as follows*:

No matter v₁ and v₂ are saddle/boundary vertices or not, once the line o₁v₃ does not pass the segment v₁v₂, we shall use the configuration shown in Figure 2(c). In detail,

a) if the intersection of the line o₁v₃ and the horizontal axis is on the left of v₁, T(v₃) = T(v₁) + || v₁v₃ || ;

b) if the intersection of the line o₁v₃ and the horizontal axis is on the right of v₂, T(v₃) = T(v₂) + || v₂v₃ || .

* But not the original method introduced in the third paragraph in the right column on page 82.

* In our implementation for the paper, we use the above mentioned correct method.
