Function Documentation

void Draw_sea

(

)

Draws the sea.

Once initialization with wave_init() is done, and after each call of wave_z_compute(), this function can be called to actually draw the sea. The code of this function contains OpenGL code.

void free_wave_variables

(

)

Free sea data memory.

Free memory allocated by wave_init().
