Extension method: IEnumerable<VertexInfo[]> Extrude(this IEnumerable<IEnumerable<PointD>>, double, bool, bool)

• Declared in: RT.Modeling.Md

Declaration

public static IEnumerable<VertexInfo[]> Extrude(
    this IEnumerable<IEnumerable<PointD>> polygons,
    double depth,
    bool includeBackFace = false,
    bool flatSideNormals = false
)

Summary

Generates a 3D model by extruding a set of polygons, potentially with holes, from 2D space along the y-axis.

Parameters

this IEnumerable<IEnumerable<PointD>>	polygons	The polygons to extrude. Polygons going clockwise are assumed to be faces, polygons going counter-clockwise are assumed to be holes.
double	depth	The amount along the y-axis by which to extrude.
bool	includeBackFace	If true, a back face is also included.
bool	flatSideNormals	If true, the “walls” of the extrusion at all assumed to be flat (normal vectors will be perpendicular). Otherwise, they are assumed to be curves (normal vectors are averages).

Returns

A collection of faces.
