DomainSurface

DomainSurfaceStr computes the outer surface or edges of a structured grid.

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

Parameters

Name	Type	Description
angle	Slider	This scalar (slider) specifies a bounding for the angle between the face normal of two connected surface parts. If the angle between these normals is less than this parameter, the corresponding feature line is not shown. The angle must be given in radians.
vertex	Vector	Normal for back-face culling
scalar	Scalar	Threshold for back-face culling
double	Boolean	Check for duplicated vertices
optimize	Choice	Optimize for memory or speed

Input Ports

Name	Type	Description
requiredMesh	StructuredGrid RectilinearGrid UniformGrid	The structured grid or a set of structured grids.
optionalData	Float Vec3	Scalar or vector data.

Output Ports

Name	Type	Description
outputSurface	Polygons	The outer surface of the grid as polygons.
dependSurfDat	Float Vec3	If the optional input port is connected, the data on the vertices of the polygons of the outer surface are available at this port.
outputLines	Lines	Edge lines
dependLinesDat	Float Vec3	If the optional input port is connected, the data on the lines are available at this port.

Examples

Figure: covise/net/examples/DomainSurfaceStr.net

We use the map covise/net/examples/DomainSurfaceStr.net. The module GenDat generates a structured grid in shape of a torus. You can see the surface in the first Renderer output. The second Renderer output shows feature lines; the angle parameter is set to 0.01.
