Methods

Area

#Example
public static double Area(this MeshFace face, Mesh mesh, out Polyline boundary)
Parameters:
face (MeshFace)
mesh (Mesh)
boundary (out Polyline)

Area

#Example
public static double Area(this MeshFace face, Mesh mesh)
Parameters:
face (MeshFace)
mesh (Mesh)

Boundary

#Example
public static Polyline Boundary(this MeshFace face, Mesh mesh)
Parameters:
face (MeshFace)
mesh (Mesh)

EdgeRange

#Example
public static (double shortest, double longest) EdgeRange(this MeshFace face, Mesh mesh)
Parameters:
face (MeshFace)
mesh (Mesh)

EdgeTouchesVertex

#Example
public static bool EdgeTouchesVertex(this Mesh mesh, int edgeIndex, int vertexIndex)
Test whether a specific topological edge involves a specific vertex. This test checks whether any of the faces using this edge also use the vertex in question.
Parameters:
mesh (Mesh)Mesh containing edges and vertices.
edgeIndex (int)Index of topological edge.
vertexIndex (int)Index of regular vertex.

FindEdge

#Example
public static int FindEdge(this Mesh mesh, int vertexA, int vertexB)
Try and find the edge index which connects vertices A and B.
Parameters:
mesh (Mesh)Mesh.
vertexA (int)First vertex index.
vertexB (int)Second vertex index.
Returns: Index of edge connecting A and B or -1.

FindNeighbours

#Example
public static bool FindNeighbours(this MeshFace face, int vertex, out int before, out int after)
Find the vertices, if any, that come before and after a given vertex around the face. This method assumes the face is valid.
Parameters:
face (MeshFace)
vertex (int)
before (out int)
after (out int)
Returns: True if vertices were found, false if otherwise.

Shade360

#Example
public static void Shade360(this Mesh mesh, Vector3f light, float lit = 0.3, float shade = 0.3)
Apply a full shading to all the vertices of a mesh. This requires vertices already having false colours.
Parameters:
mesh (Mesh)Mesh to shade.
light (Vector3f)Direction *towards* the light source.
lit (float = 0.3)Amount of lightening towards light.
shade (float = 0.3)Amount of darkening away from light.

ShadeFlat

#Example
public static void ShadeFlat(this Mesh mesh, params Color[] palette)
Apply a flat shading to all the faces of a mesh. This involves unwelding *all* edges.
Parameters:
mesh (Mesh)Mesh to colour.
palette (params Color[])Palette of colours to apply randomly.

ShadeGooch

#Example
public static void ShadeGooch(this Mesh mesh, Vector3f light, Color warm, Color cold)
Apply a gooch shading to all the vertices of a mesh. This requires vertices already having false colours.
Parameters:
mesh (Mesh)Mesh to shade.
light (Vector3f)Direction *towards* the light sourc.
warm (Color)Warm gooch colour for tinting of lit areas.
cold (Color)Cool gooch colour for tinting of shaded areas.

ShadeGooch

#Example
public static void ShadeGooch(this Mesh mesh, Vector3f light)
Apply a gooch shading to all the vertices of a mesh. This requires vertices already having false colours.
Parameters:
mesh (Mesh)Mesh to shade.
light (Vector3f)Direction *towards* the lght source.

ShadeLambertian

#Example
public static void ShadeLambertian(this Mesh mesh, Vector3f light, float lit = 0.3, float shade = -0.3)
Apply a lamberian smooth shading to all the vertices of a mesh. This requires vertices already having false colours.
Parameters:
mesh (Mesh)Mesh to shade.
light (Vector3f)Direction *towards* the light source.
lit (float = 0.3)Amount of lighting to apply to fully lit vertices.
shade (float = -0.3)Amount of darkening to apply to fully shaded vertices.

Touches

#Example
public static bool Touches(this MeshFace face, int vertex)
Test whether any of the face corners equals the vertex index.
Parameters:
face (MeshFace)
vertex (int)
