ADD_WEIGHTED

#define ADD_WEIGHTED	(		x,
			y,
			z
	)

Value:

weight = 1.0f;\
  xC = modFast128(midX + (x));\
  weight *= w[0][(x) + 1];\
  yC = modFast128(midY + (y));\
  weight *= w[1][(y) + 1];\
  zC = modFast128(midZ + (z));\
  weight *= w[2][(z) + 1];\
  result += weight * data[(zC * NOISE_TILE_SIZE + yC) * NOISE_TILE_SIZE + xC];

ADD_WEIGHTEDX

#define ADD_WEIGHTEDX	(		x,
			y,
			z
	)

Value:

weight = dw[0][(x) + 1] * w[1][(y) + 1] * w[2][(z) + 1];\
  result += weight * neighbors[x + 1][y + 1][z + 1];

ADD_WEIGHTEDY

#define ADD_WEIGHTEDY	(		x,
			y,
			z
	)

Value:

weight = w[0][(x) + 1] * dw[1][(y) + 1] * w[2][(z) + 1];\
  result += weight * neighbors[x + 1][y + 1][z + 1];

ADD_WEIGHTEDZ

#define ADD_WEIGHTEDZ	(		x,
			y,
			z
	)

Value:

weight = w[0][(x) + 1] * w[1][(y) + 1] * dw[2][(z) + 1];\
  result += weight * neighbors[x + 1][y + 1][z + 1];
