Detailed Description

Meshing routines for n-Manifold Geometry. This stuff is destined to be absorbed into nmg_fuse.c. "meshing" here refers to the sorting of faceuses around an edge as two edges sharing the same end points (vertex structs) are fused.

Function Documentation

int nmg_is_angle_in_wedge (  double  a, double  b, double  t )

N M G _ I S _ A N G L E _ I N _ W E D G E Determine if T lies within angle AB, such that A < T < B. The angle B is expected to be "more ccw" than A. Because of the wrap from 2pi to 0, B may have a smaller numeric value. Returns - -2 t is equal to a -1 t is equal to b 0 t is outside angle ab 1 t is inside angle ab Definition at line 70 of file nmg_mesh.c. References bn_twopi, and NEAR_ZERO.

int nmg_mesh_two_faces (  register struct faceuse *  fu1, register struct faceuse *  fu2, const struct bn_tol *  tol )

N M G _ M E S H _ T W O _ F A C E S Actuall do the work of meshing two faces. The two fu arguments may be the same, which causes the face to be meshed against itself. The return is the number of edges meshed. Definition at line 503 of file nmg_mesh.c.
