Not working arrays for Facet. Why?

esp1001_f2672017e2

What wrong in this code? I'm try to get vertexes in current facet.

m_normIdx [4], m_uvwIdx [4] also don't working :(

var oNode = Scene.getPrimarySelection();
if( oNode ){
var oObject = oNode.getObject();
var oShape = oObject.getCurrentShape();
var oGeometry = oShape.getGeometry();
var oFacet = oGeometry.getFacet(0);
for( k = 0; k < 4; k++ ) {
var currentVertex = oGeometry.getVertex(oFacet.m_vertIdx[k]);
~~~~~~~~~~~~~~~
}
}

TypeError: Result of expression 'oFacet.m_vertIdx' [undefined] is not an object.

Edit - while I stand by my advice below, you should also check the type of oGeometry. I don't see getFacet() in the DS 3 scripting docs, and I don't see m_vertIdx as a member of any of the facet types which may be your biggest problem - it isn't defined by you either.

---------------------------------------------------

Try adding some error checking - I suspect you're being too trusting and not ending up with a facet.

var oNode = Scene.getPrimarySelection();
if( oNode ){
 var oObject = oNode.getObject();
 if (oObject) {
  var oShape = oObject.getCurrentShape();
  if (oShape) {
   var oGeometry = oShape.getGeometry();
   if (oGeometry) {
    var oFacet = oGeometry.getFacet(0);
    if (oFacet) {
     for( k = 0; k < 4; k++ ) {
      var currentVertex = oGeometry.getVertex(oFacet.m_vertIdx[k]);
                                                                      ~~~~~~~~~~~~~~~
     }
    }
    else {
     print ( "No facet" );
    }
   }
   else {
    print ( "No geometry" );
   }
  }
  else {
   print ( "No shape" );
  }
 }
 else {
  print( "No object" );
 }
}
else {
 print( "No node" );
}

Same result with checking :(

Script Error: Line 12

From last SDK documentation:

Array of vertex indices that make up the face. m_vertIdx[3] will be -1 if this is a triangle.

That's the SDK, not the Scripting kit - they are not the same.

My fault :)

Whether there is a fresh version of Scripting kit? In DazStudio 4.5 it seems any more polygons, only triangles and quads are supported?

There are a couple of samples related to mesh generation, which isn't of course what you are doing but it may be helpful:
http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/samples/geometry/generate_plane/start
http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/samples/geometry/generate_sphere/start

You can also use Rob's trick to see what members an object has:

var object = new DzWhatever; // or get an example of the object type from the scene
for ( var n in object) {
     print( n );
}

Have you solved the problem yet?
Recently,my problem was how to add a single arrow to only one facet. Recently I installed a new version of R:

platform i386-pc-mingw32
version.string R version 2.14.2 (2012-02-29) ggplot2_0.9.0

Here is the code example
xdf <- data.frame(x=rep(1:10,each=4)<br /> ,y=rep(1:10,each=4)*rep(1:4,10) +rnorm(40,0,1)
,g=rep(c("R","S"),20)
,z=rep(c("A","A","B","B"),10)
)
head(xdf)
# plot
xp <- ggplot(xdf,aes(x=x,y=y, group=g)) +<br /> geom_line() +
facet_grid(. ~ z)
xp
# location of the arrow: x=4, y=y+1 on the top of the first facet (A)
(f1x4 <- subset(xdf,x==4 & g=="R" & z=="A")$y)<br /> arrdf <- data.frame(x = 4, y = f1x4, z = "A", g = "R") # create new data.frame for annotations<br /> # add arrow and label
xp + geom_segment(data=arrdf,aes(x=x,xend=x,y=y+3,yend=y,z=z,g=g) # <-- see the z='A'<br /> , arrow=arrow(length=unit(0.4,"cm")
)
) +
geom_text(data=arrdf,aes(x=x,y=y+4, label="a",z=z, g=g))
