Re: How I can convert this python line to clojure?
@Lars Nilson: You are right, I have take a look at vtkDataSetAttributes.java and there is not any reference to SCALARS. In vtk documentation they have included SCALARS. http://www.vtk.org/doc/nightly/html/classvtkDataSetAttributes.html#a156a8842bffd9139fa81193cca0d5bcbaefbcc1c766a1bad6e1e09d5be8388e3d And you can find SCALARS in the python example http://vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/Graphics/Python/SingleYoungsMaterialInterface.py Why is not included SCALARS in the java version?

Re: How I can convert this python line to clojure?
I would like convert this python line to clojure:
vtkCompositeDataSet.NAME()
When I read vtkCompositeDataSet.java I find this:
private native long NAME_16();
public vtkInformationStringKey NAME() {
long temp = NAME_16();
if (temp == 0) return null;
return
(vtkInformationStringKey)vtkObject.JAVA_OBJECT_MANAGER.getJavaObject(temp);
}
I have tried in clojure this, but it doesn't work :
user= (println (vtk.vtkCompositeDataSet$Attr/NAME))
#CompilerException java.lang.ClassNotFoundException:
vtk.vtkCompositeDataSet$Attr, compiling:(REPL:13)

Error converting an example written in C++, TCL, python to clojure
I would like to set up an initial centered view of a volume. I have different examples without errors of how to do it in c++, tcl and python. When I tried to translate in clojure I get errors. Where is the error in my clojure code? In C++ is as follow: ren-AddViewProp(volume); vtkCamera *camera = ren-GetActiveCamera(); double *c = volume-GetCenter(); camera-SetFocalPoint(c[0], c[1], c[2]); camera-SetPosition(c[0] + 400, c[1], c[2]); camera-SetViewUp(0, 0, -1); In TCL: ren AddViewProp volume set camera [ren GetActiveCamera] set c [volume GetCenter] $camera SetFocalPoint [lindex $c 0] [lindex $c 1] [lindex $c 2] $camera SetPosition [expr [lindex $c 0] + 400] [lindex $c 1] [lindex $c 2] $camera SetViewUp 0 0 -1 In Python: ren.AddViewProp(volume) camera = ren.GetActiveCamera() c = volume.GetCenter() camera.SetFocalPoint(c[0], c[1], c[2]) camera.SetPosition(c[0] + 400, c[1], c[2]) camera.SetViewUp(0, 0, -1) And this what I have written in Clojure (with errors): ren (doto (vtkRenderer.) (.AddViewProp volume) (- (.GetActiveCamera) (.SetFocalPoint (.GetCenter volume 0 1 2))) (- (.GetActiveCamera) (.SetPosition (.GetCenter volume 0 1 2))) (- (.GetActiveCamera) (.SetViewUp 0 0 -1)) ) -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Tree vaadin?
Harsha Sanjeewa has translated the vaadin example of the tree in clojure. The source is here https://github.com/hsenid-mobile/clj-vaadin. It is very useful to begin working with clojure and vaadin.

How to convert a VTK example from java to clojure?
I have tried to convert the example Cone5.java from VTK to clojure. I have
write this ... but it doesn't work. Do you have any suggestion?
*The original java:*
import vtk.*;
public class Cone5 {
static {
System.loadLibrary(vtkCommonJava);
System.loadLibrary(vtkFilteringJava);
System.loadLibrary(vtkIOJava);
System.loadLibrary(vtkImagingJava);
System.loadLibrary(vtkGraphicsJava);
System.loadLibrary(vtkRenderingJava);
}
public static void main (String []args) throws Exception {
vtkConeSource cone = new vtkConeSource();
cone.SetHeight( 3.0 );
cone.SetRadius( 1.0 );
cone.SetResolution( 10 );
vtkPolyDataMapper coneMapper = new vtkPolyDataMapper();
coneMapper.SetInputConnection(cone.GetOutputPort());
vtkActor coneActor = new vtkActor();
coneActor.SetMapper(coneMapper);
vtkRenderer ren1 = new vtkRenderer();
ren1.AddActor(coneActor);
ren1.SetBackground(0.1, 0.2, 0.4);
vtkRenderWindow renWin = new vtkRenderWindow();
renWin.AddRenderer( ren1 );
renWin.SetSize(300, 300);
ren1.ResetCamera();
ren1.GetActiveCamera().Azimuth(90);
vtkRenderWindowInteractor iren = new vtkRenderWindowInteractor();
iren.SetRenderWindow(renWin);
vtkInteractorStyleTrackballCamera style =
new vtkInteractorStyleTrackballCamera();
iren.SetInteractorStyle(style);
iren.Initialize();
iren.Start();
}
}
*
My modified version in clojure with errors:*
(ns project.core
(:import (vtk vtkConeSource vtkPolyDataMapper vtkRenderWindow
vtkRenderWindowInteractor vtkCamera vtkActor vtkRenderer
vtkInteractorStyleTrackballCamera)))
(defn main []
(let [cone (doto (vtkConeSource.)
(.SetHeight 3.0)
(.SetRadius 1.0)
(.SetResolution 10))
coneMapper (doto (vtkPolyDataMapper.)
(.SetInputConnection(.GetOutputPort cone)))
coneActor (doto (vtkActor.)
(.SetMapper coneMapper))
ren (doto (vtkRenderer.)
(.AddActor coneActor)
(.SetBackground 0.1 0.2 0.4)
(.ResetCamera)
(.GetActiveCamera.Azimuth 90))
renWin (doto (vtkRenderWindow.)
(.AddRenderer ren)
(.SetSize 300 300))
iren (doto (.vtkRenderWindowInteractor.)
(.SetRenderWindow renWin)
(.SetInteractorStyle vtkInteractorStyleTrackballCamera.)
(.Initialize)
(.Start))
]))
