VADIAVisionX V4 NAME

vadia − compute diameters of a triangular mesh model.

SYNOPSIS

vadia if=<vectorfile> layer=<modellayer> division=<modeldivision> xres=<> yres=<> zres=<> of=<diametervector>

DESCRIPTION

vadia

vadia takes in a vector file containing the representation of a triangular mesh model (output from vamea) and computes the diameter for each ring of the model. The input if contains coordinates of the vertices in the triangular model as well as which triangular ring the vertices belong to. Diameter is computed based on the estimated perimeter of each ring.

CONSTRAINT

Input file if is output (of3) from vamea. It contains the vertices coordinates and the number of ring they belong to. layer and division are the same as in vamea. They are the configuration parameters for the triangular mesh model. xres, yres and zres are the resolutions. The output of is a vector file, each element of which contains the diameter (mm), x, y and z coordinates of the center of a ring in the model.
