Input/Output

readFile(Type, filename::String)

Read a Gismo object from a file.

Arguments

• Type: The type of object to read (e.g., BSplineBasis, TensorBSpline{2}, Nurbs, etc.)
• filename: Path to the file to read

Returns

An object of the specified type read from the file

Supported Types

• Basis types: BSplineBasis, TensorBSplineBasis{1/2/3}, NurbsBasis, TensorNurbsBasis{1/2/3}
• Geometry types: BSpline, TensorBSpline{1/2/3}, Nurbs, TensorNurbs{2/3}

Examples

# Read a B-spline surface
surface = readFile(TensorBSpline{2}, "surface.xml")

# Read a NURBS curve
curve = readFile(Nurbs, "curve.xml")

# Read a basis
basis = readFile(TensorBSplineBasis{2}, "basis.xml")

Details

Reads Gismo XML format files containing geometric or basis function data.

writeParaview(geo::gsGeometry, fn::String; npts=1000, mesh=false, ctrlNet=false)
writeParaview(basis::gsBasis, fn::String; npts=1000, mesh=false)
writeParaview(basis::gsBasis, indices::Vector{Int}, fn::String; npts=1000, mesh=false)

Export TinyGismo geometries and bases to Paraview VTK files.

Arguments

• geo: Geometry to export (B-spline or NURBS)
• basis: Basis to export (B-spline or NURBS)
• indices: Basis function indices to export (1-indexed)
• fn: Output filename
• npts: Number of sampling points (default: 1000)
• mesh: Plot parameter mesh (default: false)
• ctrlNet: Plot control net (geometry export only, default: false)

Details

• Geometry export writes the shape with optional mesh and control net.
• Basis export writes all basis functions, or only the specified indices.

writeParaviewBasisFnct(i::Int, basis::gsBasis, fn::String; npts=1000)

Export a single basis function to a Paraview file.

Arguments

• i: Index of the basis function (1-indexed)
• basis: The B-spline or NURBS basis
• fn: Output filename
• npts: Number of sampling points (default: 1000)

Details

Exports a single basis function as a curve/surface in VTK format.

• X, Y, Z: 1×n coordinate arrays for structured point sets
• V: 1×n scalar values for each point (optional)
• fn: Output filename

Details
