BME_JEKV

JOIN EDGE KILL VERT: Takes a an edge and pointer to one of its vertices and collapses the edge on that vertex.

Before: OE KE ------- ------- | || | OV KV TV

After: OE --------------- | | OV TV

Restrictions: KV is a vertex that must have a valance of exactly two. Furthermore both edges in KV's disk cycle (OE and KE) must be unique (no double edges).

It should also be noted that this euler has the possibility of creating faces with just 2 edges. It is up to the caller to decide what to do with these faces.

Returns - 1 for success, 0 for failure.

	)		`[read]`

BME_JFKE

JOIN FACE KILL EDGE:

Takes two faces joined by a single 2-manifold edge and fuses them togather. The edge shared by the faces must not be connected to any other edges which have Both faces in its radial cycle

Examples:

A B ---------- ---------- | | | | | f1 | | f1 | v1========v2 = Ok! v1==V2==v3 == Wrong! | f2 | | f2 | | | | | ---------- ----------

In the example A, faces f1 and f2 are joined by a single edge, and the euler can safely be used. In example B however, f1 and f2 are joined by multiple edges and will produce an error. The caller in this case should call BME_JEKV on the extra edges before attempting to fuse f1 and f2.

Also note that the order of arguments decides whether or not certain per-face attributes are present in the resultant face. For instance vertex winding, material index, smooth flags, ect are inherited from f1, not f2.

Returns - A BME_Poly pointer

FLIP FACE EULER

Changes the winding order of a face from CW to CCW or vice versa. This euler is a bit peculiar in compairson to others as it is its own inverse.

TODO: reinsert validation code.

MAKE EDGE EULER:

Makes a single wire edge between two vertices. If the caller does not want there to be duplicate edges between the vertices, it is up to them to check for this condition beforehand.

SPLIT FACE MAKE EDGE:

Takes as input two vertices in a single face. An edge is created which divides the original face into two distinct regions. One of the regions is assigned to the original face and it is closed off. The second region has a new face assigned to it.

Examples:

Before: After: ---------- ---------- | | | | | | | f1 | v1 f1 v2 v1======v2 | | | f2 | | | | | ---------- ----------

Note that the input vertices can be part of the same edge. This will result in a two edged face. This is desirable for advanced construction tools and particularly essential for edge bevel. Because of this it is up to the caller to decide what to do with the extra edge.

Returns - A BME_Poly pointer
