3D – These transformers create and modify three-dimensional surface and solid geometries.
CSGBuilder Creates Constructive Solid
Geometry (CSG) from pairs of
solid geometry features.
CSGEvaluator Replaces the geometry of a feature that has CSG.
Extruder Creates long, surface or solid
geometries with a fixed crosssectional
profile taken from the
original geometry of the feature.
FaceReplacer Replaces the geometry of a feature from donut or polygon to face. A
face is a planar area in 3D space. The planar structure can be a raster, a
polygon, or a donut.
SurfaceReverser Reverses surfaces and solids. On surfaces, it will reorder the coordinates
of the surface such that the normal of the output surface is the opposite
of the input surface. Vertex normals that exist on the surface will be also
be reversed. On solids, it will reverse the underlying surfaces, in effect
causing the solid to be turned inside-out.
CALCULATORS – These transformers calculate a value and supply it to a new attribute on a feature.
AngularityCalculator Calculates the angularity of a linear or area feature. Angularity indicates
the degree of curvature of a feature—the higher the value, the more
curved its geometry.
