Function
Creates triangle connections for a field of scattered positions.
Syntax
output = Connect(input, method, normal);
Inputs
| Name | Type | Default | Description |
|---|---|---|---|
| input | field or vector list | none | field with positions to be connected |
| method | string | "triangulation" | connection method to be used |
| normal | vector | [0 0 1] | normal to the projection plane |
Outputs
| Name | Type | Description |
|---|---|---|
| output | field | connected field |
Functional Details
The triangle connections created by this module form a surface.
input | should be (1) a field with a 2- or 3-dimensional component or (2) a list of 2- or 3-dimensional vectors. In the second case, the vectors are interpreted as positions. |
method | specifies the method of connection. At present, Delaunay "triangulation" (involving Voronoi tesselation of a plane) is the only method supported. |
normal | specifies the plane to which 3-dimensional positions are projected before triangulation is computed. Note that the output positions will be the original 3-dimensional points. |
Degenerate triangles (i.e., those with colinear vertices) are not included in the output object.
Components
Adds a "connections" component. All components that depend on the "positions" component are unchanged in the output.
