示例1: colorAt
# 需要导入模块: import Helper [as 别名]
# 或者: from Helper import normalize [as 别名]
def colorAt(self, ray, t, objectlist):
sp = ray.pointAtParameter(t) # Schnittpunkt am Objekt
d = ray.direction
n = self.normalAt(sp)
Ca = np.array(self.color)
c_out = 0
for light_source in helper.light_sources:
light = helper.normalize(sp - light_source) # Vektor vom Licht zum Schnittpunkt
lr = light - 2 * np.dot(n, light) * n
lightV = helper.normalize(light_source - sp)
c_ambient = Ca * helper.ka
c_diffus = helper.Cin * helper.kd * np.dot(lightV, n)
c_spec = helper.Cin * helper.ks * math.pow(np.dot(lr, d), 32)
