Simulation Research for Petal Color

The petal color was represented by parametric equation and the parameters were in connection with parametric equation of petal shape. The initial petal shape was represented by a rectangle parametric equation. Combining the petal shape feature, we changed the rectangle equation into petal parametric equation. According to the parameters in petal equation, we may get the model of flower garland and flower costal to control hue, intensity and saturation (HIS). These color models may be combined to form complex flower color. The model can be realized quickly and two kinds of flower simulation result show that the method is effective.
