IndexManifolds

You can choose a dimension and an index of a structured grid refering to this dimension. IndexManifolds calculates the surface of this area. If you work with uniform or rectilinear grids the result will be a plane.

IndexManifolds is available for COVISE version 4.5 and higher. It's available for all supported platforms.

Parameters

Name	Type	Description
DirChoice	choice of - direction x - direction y - direction z	Dimension the index is refering to.
xIndex	Slider	Index of structured grid area. The range of the slider is set acoording to the input grid.
yIndex	Slider	Index of structured grid area. The range of the slider is set acoording to the input grid.
zIndex	Slider	Index of structured grid area. The range of the slider is set acoording to the input grid.
Generate_strips	Boolean	Do you want to generate triangle strips?

Input Ports

Name	Type	Description
requiredGrid	UniformGrid RectilinearGrid StructuredGrid	The grid or sets of grids you want to use.
optionalData	Float Vec3	Data on grid points.

Output Ports

Name	Type	Description
outputSurface	Polygons TriangleStrips	Generated surface.
dependSurface Data	Unstructered_S3D_Data Unstructered_V3D_Data	Data on the surface.

Examples

Example 1:

Figure: Example 1 for IndexManifolds (Map)

We use the example map above together with the parameter settings as shown in the Control Panel. The module GenDat generates a structured grid in cylindrical shape. IndexManifolds displays the surface of one area. The result therefore is also a cylinder as you can see in the Renderer output below.

Example 2:

The second example (covise/net/examples/IndexManifolds.net) illustrates the usage of IndexManifolds for a rectilinear grid.
