| Abstract: | The solid texture based on random noise and perturbation is used to realize the random texture with easy parameterization for non-planed object. The fractal iteration is introduced into the specific perturbation algorithm. In order to improve the calculation speed for practical use, the Parlin noise function is simplified and the render algorithm with ray follow-up is used to give a better result. |
