摘要
提出一种多维数据3D空间可视化方法。在二维径向坐标映射基础上,引入雷达图的面积特征作为第三维,构成三维径向坐标映射。基于超复数实现径向坐标在3D空间的计算。实验结果表明,三维映射较二维映射更能反映数据结构信息,有效处理了二维径向坐标映射中映射数据点易堆叠的问题。
A multidimensional visualization technique that creates a 3D representation of n-dimensional data is proposed. The area of radar chart is introduced to 2D radial coordinate visualization to expand it to 3D space. The projection of 3D radial coordinate visualization is computed by hypercomplex matrix. Compared to 2D projection, which visual cluttering and object occlusion are still a problem, the 3D projection conveys more information, giving the user more control of the visual representation.
