Function Documentation

vec3 CreateWave	(	float	w,
		float	A,
		vec2	D,
		float	Q,
		float	phi
	)

Computes displacement for gerstner waves.

Parameters:

	w	the spatial frequency of the wave
	A	the amplitude of the wave
	D	the direction (i.e. wave vector) of the wave
	Q	the steepness of the wave
	phi	the temporal frequency of the wave

Returns:

the displacement vector

vec2 GetTexCoord

(

vec2

k

)

Computes texture coordinates.

Calculates texture coordinates for the noise texture for waves moving with wave vector k.

Parameters:

The

wave vector for the wave (i.e direction and speed of the wave)

Returns:

the calculated texture coordinates
