ALIGN POINTS SCRIPT - Help need
« on: May 13, 2011, 05:39:48 pm »

Hi Guys,

so i have this script for many time,
its work for me, but i think then can be better. :)

i show example:


i need..


here the script:
Code: [Select]
/*
  *Name: Aling points to (x,y,z)
  *CopyLeft: 2010
  *Author: Neirão
  *Date: 03/03/10
  *Description: based in Vytautas_alinhar_pontos_line_points_v1
  *Parameters:  *= width;  *= height;  *= width_divisions;  *= height_divisions;
  */

/***** Init *****/
#command("object");
object $object;
shape $shapes[0];
shape $shape;
int $shape_count;
point3 $points[0];
point3 $point;
int $point_count;
int $i;
int $j;
int $direction;

if (GUI.Xenabled) $direction = 0;
else if (GUI.Yenabled) $direction = 1;
else $direction = 2;

if (GUI.Xenabled && GUI.Yenabled && GUI.Zenabled) $direction = 3;

meshdata $mesh_data;
$object = project.curObject;
$shape_count = $object.GetShapes($shapes);

/*** Get all selected points from all the shapes ***/

for $i = 0 to $shape_count - 1 do{
$shape = $shapes[$i];

/* If shape is a mesh.. */
if($shape.GetKind() == SHAPE_KIND_MESH){

/* i try this..but dont work.. :( --> || $shape.GetKind() == SHAPE_KIND_SUBDIVISION */

/* Get the shape point number */
$point_count = $shape.GetNumPoints();

for $j = 0 to $point_count - 1 do{
if($shape.GetPointSelected($j)) {
$point = $shape.GetPoint($j);
if($direction == 0){
$point.x = 0;
}
if($direction == 1){
$point.y = 0;
}
if($direction == 2){
$point.z = 0;
}
/* TODOS XYZ ATIVADOS alinha todos para  */
if($direction == 3){
$point.x = 0;
$point.y = 0;
$point.z = 0;
}
$shape.SetPoint($j, $point);
}
}
}
}

can someone maker this correction??! ::)
thanks !

Neirao,
Below is your code with the changes you requested:
Code: [Select]
/*
  *Name: Aling points to (x,y,z)
  *CopyLeft: 2010
  *Author: Neirão
  *Date: 03/03/10
  *Description: based in Vytautas_alinhar_pontos_line_points_v1
  *Parameters:  *= width;  *= height;  *= width_divisions;  *= height_divisions;
  */

/***** Init *****/

shape $shape;
int $shape_count;

point3 $point;
int $point_count;
int $i;
int $j;
int $direction;

/* added by NickE */
point3 $sel_max,$sel_min,$sel_center;

/* end of added by NickE */

if (GUI.Xenabled) $direction = 0;
else if (GUI.Yenabled) $direction = 1;
else $direction = 2;

if (GUI.Xenabled && GUI.Yenabled && GUI.Zenabled) $direction = 3;

meshdata $mesh_data;
$object = project.curObject;
$shape_count = $object.GetShapes($shapes);

/*** Get all selected points from all the shapes ***/

for $i = 0 to $shape_count - 1 do{
$shape = $shapes[$i];

/* If shape is a mesh.. */
if($shape.GetKind() == SHAPE_KIND_MESH){

           {
              $point = $shape.GetPoint($j);
              if ($point.x > $sel_max.x) $sel_max.x = $point.x;
              if ($point.y > $sel_max.y) $sel_max.y = $point.y;

$point.x = 0;
$point.y = 0;
$point.z = 0;
}
$shape.SetPoint($j, $point);
}
}
}
}

Some things to think about:
1) Do you really want the center, or do you really want the average?
2) This script works on the actual coordinates of the points, so if a mesh is moved or rotated, it still operating on the underlying point coordinates rather than the transformed coordinates.  This may give different results than what is expected.
