摘要
几何模型技术在动漫制作中占据极为重要的地位,为进一步提高水墨动漫场景的图画质量,基于几何模型技术设计了三维水墨动漫场景设计方法。通过选择模型基准点计算平均曲率,得到均方根曲率值,再根据均方根曲率值与设定阈值的关系,判定某点是否能够作为模型基准点。建立动漫场景典型空间坐标系,获取三维点云模型空间原点的位置,计算欧氏距离,获取坐标转化规律。设计基于三维点云模型的场景构造算法,得到动漫场景构造设计方法。验证实验结果显示,在6个场景图像中,设计方法的信噪比(Signal-to-Noise Ratio,SNR)值高于50 dB,画面质量较好。在鲁棒性测试中,设计方法在不同攻击指标下的客观参数值较低。由此可见,通过设计方法可以得到图像效果较好的三维水墨动漫场景。
Geometric model technology plays an important role in animation production.In order to further improve the picture quality of ink animation scenes,the design method of 3D ink animation scenes is designed based on geometric model technology.Select the model reference point,calculate the average curvature,get the root mean square curvature value,and determine whether a point can be used as the model reference point according to its relationship with the set threshold.Establish a typical space coordinate system of animation scene,obtain the position of the three-dimensional point cloud model space origin,calculate Euclidean distance,and obtain the coordinate transformation rules.Design the scene construction algorithm based on 3D point cloud model,and get the animation scene construction design method.The experimental results show that the Signal-to-Noise Ratio(SNR) value of this method is higher than 50 dB in six scene images,which shows that the image quality is good.In the robustness test,the objective parameter values of this method under different attack indicators are low,so it can be seen that 3D ink animation scenes with good image effects can be obtained through this method.
