Algorithm (Workflow)
This function, VLFLcat2, is designed to concatenate two sets of vertex and facet lists. It is part of the SolidGeometry library and is used to append one vertex list and one facet list to another without performing any checks.
Input Parameters
- V1: The first vertex list. It is a matrix where each row represents a vertex in 3D space.
- F1: The first facet list. It is a matrix where each row represents a facet, defined by indices pointing to rows in the vertex list
V1.
- V2: The second vertex list, similar in structure to
V1.
- F2: The second facet list, similar in structure to
F1, but pointing to rows in V2.
Output Results
- VL: The concatenated vertex list, which is a combination of
V1 and V2.
- FL: The concatenated facet list, which combines
F1 and F2, with the indices in F2 adjusted to account for the additional vertices from V1.
Algorithm Steps
- Check the size of
V1 to determine if it is empty. If V1 is empty, the function returns V2 and F2 as the concatenated lists.
- Concatenate
V1 and V2 vertically to form the new vertex list VL.
- Concatenate
F1 and F2 vertically to form the new facet list FL. Adjust the indices in F2 by adding the number of vertices in V1 to each index, ensuring that the indices in F2 correctly reference the combined vertex list.
