Introduction
Reports volume and other statistics of a wireframe model.
Note that the NOSID parameter will have an effect on wireframe volume calculations.
TRIVOL supports the following recently-added parameters:
The ZONE field -------------------- TRIVOL now supports alpha ZONE fields of up to 10 characters long. Records with absent ZONE values are counted and reported as a warning but a volume is still calculated for absent ZONES. The name of the input triangle file to TRIVOL is now recorded in an implicit field in the output results file produced by TRIVOL. |
