sort_mesh - Procedure

Sort mesh faces


Description

Returns an array of indexes to mesh faces sorted with respect to their largest X, Y or Z-coordinate. The three vertices of each face are compared to find the vertex with the largest coordinate. These vertices are then sorted in increasing order and the indexes of their faces returned. For each face it's max and min coordinate is also computed. Sorting and max/min calculation is done relative to theVARKON  BASIC coordinate system.

Syntax

getvertex(id, dir, facelist, min, max)

REF	id;
STRING	dir;
INT	facelist(n_faces);
FLOAT	min(n_faces);
FLOAT	max(n_faces);

Principal parameters

id	- Global identity of a mesh
dir	- "X", "Y" or "Z"
facelist	- Array of integers to recieve the indexes of the faces sorted
min	- Array of floats to recieve the min values
max	- Array of floats to recieve the max values

Optional parameters

None.
