Detailed Description

abstract superclass for non-linear cells

vtkNonLinearCell is an abstract superclass for non-linear cell types. Cells that are a direct subclass of vtkCell or vtkCell3D are linear; cells that are a subclass of vtkNonLinearCell have non-linear interpolation functions. Non-linear cells require special treatment when tessellating or converting to graphics primitives. Note that the linearity of the cell is a function of whether the cell needs tessellation, which does not strictly correlate with interpolation order (e.g., vtkHexahedron has non-linear interpolation functions (a product of three linear functions in r-s-t) even thought vtkHexahedron is considered linear.)

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkCell.

Reimplemented in vtkQuadraticEdge, vtkQuadraticHexahedron, vtkQuadraticLinearQuad, vtkQuadraticLinearWedge, vtkQuadraticPolygon, vtkQuadraticPyramid, vtkQuadraticQuad, vtkQuadraticTetra, vtkQuadraticTriangle, vtkQuadraticWedge, vtkTriQuadraticHexahedron, and vtkTriQuadraticPyramid.

◆ IsLinear()

int vtkNonLinearCell::IsLinear ( )
inlineoverridevirtual

Non-linear cells require special treatment (tessellation) when converting to graphics primitives (during mapping).

The vtkCell API IsLinear() is modified to indicate this requirement.
