The Visualization Toolkit also provides some of its own file formats. The main reason for creating yet another data file format is to offer a consistent data representation scheme for a variety of dataset types, and to provide a simple method to communicate data between software. Whenever possible, we recommend that you use formats that are more widely used. ![]() Matlab Read Vtk File Format Serial Formats ThatThe simplest are the legacy, serial formats that are easy to read and write either by hand or programmatically. However, these formats are less flexible than the XML based file formats described later in this section. Matlab Read Vtk File Format Portable Data CompressionThe XML formats support random access, parallel IO, and portable data compression and are preferred to the serial VTK file formats whenever possible. Simple Legacy Formats The legacy VTK file formats consist of five basic parts. This part contains the single line: vtk DataFile Version x.x. This line must be exactly as shown with the exception of the version number x.x, which will vary with different releases of VTK. Note: the current version number is 3.0. Version 1.0 and 2.0 files are compatible with version 3.0 files.) The second part is the header. The header consists of a character string terminated by end-of-line character n. The header can be used to describe the data and include any other pertinent information. The file format describes the type of file, either ASCII or binary. The geometry part describes the geometry and topology of the dataset. This part begins with a line containing the keyword DATASET followed by a keyword describing the type of dataset.Then, depending upon the type of dataset, other keyworddata combinations define the actual data. This part begins with the keywords POINTDATA or CELLDATA, followed by an integer number specifying the number of points or cells, respectively. It doesnt matter whether POINTDATA or CELLDATA comes first.) Other keyworddata combinations then define the actual dataset attribute values (i.e., scalars, vectors, tensors, normals, texture coordinates, or field data). An overview of the file format is shown in Figure 1: vtk DataFile Version 2.0 (1) Really cool data (2) ASCII BINARY (3) DATASET type. POINTDATA type. CELLDATA type.
