The form of the multiplier disturbance in the ocean file disturbance section is
grid_type multiplier_grid
n_points_x 1536
n_points_y 1536
dx 0.1
dy 0.1
detail_file multiplier_field.dat
position_x 0
position_y 0
orientation 0
velocity 100
direction 0
And the form for the additive Height grid is:
grid_type height_grid
n_points_x 1536
n_points_y 1536
dx 0.25
dy 0.25
detail_file height_field.dat
position_x 0
position_y 0
orientation 20
velocity 0
direction 20
These disturbances have nearly identical forms in the ocean file. In the referenced detai files, the differences are more critical:
For the multiplicative height fields, the detail file is:
RenderWorld_data_file multiplier_grid 1 1
multilplier_file wake2.img
number_of_scaling_key_times: 1
time scales
0. 0.
end
The hdf file wake2.img contains a single array representing the multiplicative factor to be applied to the oceans surface. The scaling factor listed here as changing over time affects the ocean surface as an exponent power on the data. The hdf file is rescaled by raising the multiplier value to the scale power.
For the height disturbance in the example below, the scaling parameter is now applied direct to the height_grid as a multiplicative factor.
RenderWorld_data_file height_grid 1 1
height_file_name: wake2.img
number_of_scaling_key_times: 4
time scale
0 0
1 1
2 3
4 0
