* Directional, sinusoidal wave effect.

|
* @param wave A 5-dimensional data structure describing the wave: first member is the amplitude,
|
1094
|
* second is the wave length, third is the phase (i.e. when phase = PI/2, the sine
|
1095
|
* wave at the center does not start from sin(0), but from sin(PI/2) ) and the next two
|
1096
|
* describe the 'direction' of the wave.
|
1097
|
* <p>
|
1098
|
* Wave direction is defined to be a 3D vector of length 1. To define such vectors, we
|
1099
|
* need 2 floats: thus the third member is the angle Alpha (in degrees) which the vector
|
1100
|
* forms with the XY-plane, and the fourth is the angle Beta (again in degrees) which
|
1101
|
* the projection of the vector to the XY-plane forms with the Y-axis (counterclockwise).
|
1102
|
* <p>
|
1103
|
* <p>
|
1104
|
* Example1: if Alpha = 90, Beta = 90, (then V=(0,0,1) ) and the wave acts 'vertically'
|
1105
|
* in the X-direction, i.e. cross-sections of the resulting surface with the XZ-plane
|
1106
|
* will be sine shapes.
|
1107
|
* <p>
|
1108
|
* Example2: if Alpha = 90, Beta = 0, the again V=(0,0,1) and the wave is 'vertical',
|
1109
|
* but this time it waves in the Y-direction, i.e. cross sections of the surface and the
|
1110
|
* YZ-plane with be sine shapes.
|
1111
|
* <p>
|
1112
|
* Example3: if Alpha = 0 and Beta = 45, then V=(sqrt(2)/2, -sqrt(2)/2, 0) and the wave
|
1113
|
* is entirely 'horizontal' and moves point (x,y,0) in direction V by whatever is the
|
1114
|
* value if sin at this point.
|
1115
|
* @param center 3-dimensional Data that, at any given time, returns the Center of the Effect.
|
1116
|
* @return ID of the effect added, or -1 if we failed to add one.
