The analyze stage of each of the various healing phases determines recommended tolerance values to be used. These tolerance values provide good results and optimal performance for most models. However, you may need to change some tolerances for particular models. The tolerances you may want to change include:
|
|
|
Geometry simplification tolerance
|
|
|
Minimum and maximum stitching tolerances
|
|
|
Geometry building tolerances
|
|
|
The tolerances are stored in attributes attached to the body. They can be modified in
C++ using methods of the attribute classes, or in Scheme using Scheme extensions.
|
|
|
HEAL provides a set of callback functions that are called after each analysis stage of the healing process (e.g., after stitch analysis). These callback functions can be used for such things as redefining the default tolerances set by
HEAL. Refer to the Scheme file
scm_ah.cxx for an implementation example.
