可视化工具包支持五种不同的数据集格式:结构化点(structured points)、结构化网格(structured grid)、直线型网格(rectilinear grid)、非结构化网格(unstructured grid)和多边形数据(polygonal data)。具有隐式拓扑的数据(结构化数据,例如vtkImageData和vtkStructuredGrid)的顺序是x增长最快,然后是y,然后是z。 这些格式如...
1.1 Dataset Format _ 定义几何/拓扑数据和关系 VTK支持5种数据集格式:structured points, structured grid, rectilinear grid, unstructured grid, and polygonal data. 这里只描述非结构化网格,其他不说,用不到. 1.2 Unstructured Grid 非结构化网格数据集由任何可用的单元类型的任意组合组成(比如四六面体混合).非结...
I would like to render scalar data on a structured grid that pass a certain threshold (for example, see below) I have tried with vtk. See the following snippet below for my code grid.SetPoints(points) grid.SetDimensions(nx,ny,nz) grid.GetPointData().SetScalars(scalars) threshold ...
