Class Method Details

.clerp(min, max, weight) ⇒ Object

# File 'lib/kawaii/helpers.rb', line 7

def self.clerp min, max, weight
	weight2 = (1.0 - Math::cos(weight * Math::PI)) / 2.0
	min * (1.0 - weight2) + max * weight2
end

.lerp(min, max, weight) ⇒ Object

# File 'lib/kawaii/helpers.rb', line 3

def self.lerp min, max, weight
	min + (max - min) * weight
end

.smooth_step(y0, y1, y2, y3, mu) ⇒ Object

# File 'lib/kawaii/helpers.rb', line 12

def self.smooth_step y0, y1, y2, y3, mu

	mu2 = mu*mu
	a0 = y3 - y2 - y0 + y1
	a1 = y0 - y1 - a0
	a2 = y2 - y0
	a3 = y1

	(a0*mu*mu2+a1*mu2+a2*mu+a3)
