How to export to .obj all furniture seperately.
Hello,
what I am trying to do now (you can also see my previous question) is to export first the home with the walls and then one by one all the furniture. So, what I have changed is the script HomePane.java, first by setting 4 public variables.
// Used in the export public static int k = 0; public static int m = 0; public static int l = 0; public static String a;
and afterwards I have changed the following
/** * Exports the objects of the 3D view to the given OBJ file. */ public void exportToOBJ(String objFile) throws RecorderException { System.out.printf("Exporttoobj\n"); String header = this.preferences != null ? this.preferences.getLocalizedString(HomePane.class,"exportToOBJ.header", new Date()): "";
// Added from this point... // In the beginning k=0, l=0, m=0 // Count how many pieces of furniture are placed in the house during the first control objFile = ""; for (HomePieceOfFurniture piece : home.getFurniture()) { if (piece.isVisible()) { // In the end m shows how many furniture there are m++; } }
// A table used to save the names of the furniture with the "m" that we counted before String [] Furniture = new String[m];
a = ""; for (HomePieceOfFurniture piece : home.getFurniture()) { if (piece.isVisible()) { // "a" is used to save the name of the furniture piece a = piece.getName(); Furniture[l] = a; //System.out.printf(Furniture[m]); l++; } } // l is used for the array Furniture[m] l = 0;
//for(k=0;k<l+1;k++) //{ // Use a clone of home to ignore selection // For the room if(k==0) { objFile = "room"; //System.out.printf(objFile + "\n"); OBJExporter.exportHomeToFile(home.clone(), objFile, header); } if(k>0 && k<=m) { for (HomePieceOfFurniture piece : home.getFurniture()) { if (piece.isVisible()) { // "a" is used to save the name of the furniture piece String a = piece.getName(); Furniture[l] = a; objFile = Furniture[l]; OBJExporter.exportHomeToFile(home.clone(), objFile, header); //System.out.printf(Furniture[m]); l++; } //} } } }
/** * Export to OBJ in a separate class to be able to run HomePane without Java 3D classes. */ private static class OBJExporter { public static void exportHomeToFile(Home home, String objFile, String header) throws RecorderException { OBJWriter writer = null; boolean exportInterrupted = false; try { writer = new OBJWriter(objFile, header, -1);
List<Selectable> emptySelection = Collections.emptyList(); home.setSelectedItems(emptySelection); if (home.getWalls().size() > 0) { // Create a not alive new ground to be able to explore its coordinates without setting capabilities Rectangle2D homeBounds = getExportedHomeBounds(home); Ground3D groundNode = new Ground3D(home, (float)homeBounds.getX(), (float)homeBounds.getY(), (float)homeBounds.getWidth(), (float)homeBounds.getHeight(), true); writer.writeNode(groundNode, "ground"); } int i = 0; // The first time, we want to export the only the walls and the room if (k==0) { System.out.printf("Walls\n");
// Write 3D walls
for (Wall wall : home.getWalls()) { // Create a not alive new wall to be able to explore its coordinates without setting capabilities Wall3D wallNode = new Wall3D(wall, home, true, true); writer.writeNode(wallNode, "wall_" + ++i); } } System.out.println(m); i = 0; if (k>0 && k<=m) { //Write 3D furniture for (HomePieceOfFurniture piece : home.getFurniture()) { if (piece.isVisible() && a == piece.getName()) { System.out.print(k + "\n"); System.out.printf("Furniture\n"); // Create a not alive new piece to be able to explore its coordinates without setting capabilities // I set as home = null HomePieceOfFurniture3D pieceNode = new HomePieceOfFurniture3D(piece, null, true, true); writer.writeNode(pieceNode); k++; } } }
if (k==0) { // Write 3D rooms i = 0; for (Room room : home.getRooms()) { System.out.printf("Room\n"); // Create a not alive new room to be able to explore its coordinates without setting capabilities Room3D roomNode = new Room3D(room, home, false, true, true); writer.writeNode(roomNode, "room_" + ++i); k++; } } } catch (InterruptedIOException ex) { exportInterrupted = true; throw new InterruptedRecorderException("Export to " + objFile + " interrupted"); } catch (IOException ex) { throw new RecorderException("Couldn't export to OBJ in " + objFile, ex); } finally { if (writer != null) {
try { writer.close(); // Delete the file if exporting is interrupted if (exportInterrupted) { new File(objFile).delete(); } } catch (IOException ex) { throw new RecorderException("Couldn't export to OBJ in " + objFile, ex); } } } }
The result is that everything is exported, I mean all the furniture and the room seperately, but the saved file has kind: Document, according to info. Furthermore, I can open it with txt.

Re: How to export to .obj all furniture seperately.
So, what I finally did and it worked is:
I first added in the HomePane.java
// Used in the export public static int m = 0; public static int o = 0; public static String a;
public static String objFile
;
Afterwards, I changed the HomeController.java and especially exporttoObj
public void exportToOBJ() {
// Added from this point... // In the beginning k=0, l=0, m=0 // Count how many pieces of furniture are placed in the house during the first control //-------------------------------COUNT THE FURNITURE------------------------------------ HomePane.m = 0; HomePane.objFile = ""; for (HomePieceOfFurniture piece : home.getFurniture()) { if (piece.isVisible()) { // In the end m shows how many furniture there are HomePane.m++; } }
// I add one, so that I can store "Room" in it. HomePane.m = HomePane.m + 1; System.out.printf (HomePane.m + "\n"); //------------------------------------SAVE THE ARRAY------------------------------------ // A table used to save the names of the furniture with the "m" that we counted before String [] temp = new String[HomePane.m + 1]; temp[0] = "Room";
String [] Furniture = new String[HomePane.m]; int z; for (z = 0; z < HomePane.m ; z++) { Furniture[z] = temp[z]; }
// l is used for the array Furniture[m] and it will be used again HomePane.o = 0;
// For the room //-----------------------------------CALL THE FUNCTION---------------------------------- for (HomePane.o = 0; HomePane.o < HomePane.m ; HomePane.o++) { // System.out.printf (HomePane.o + "\n"); // System.out.printf(Furniture[HomePane.o] + "\n"); HomePane.a = Furniture[HomePane.o]; HomePane.objFile = Furniture[HomePane.o]; // System.out.printf(objFile + "\n"); // Use a clone of home to ignore selection final String objName = getView().showExportToOBJDialog(this.home.getName()); if (objName != null) { // Export 3D view in a threaded task Callable<Void> exportToObjTask = new Callable<Void>() { public Void call() throws RecorderException { getView().exportToOBJ(objName); return null; } }; ThreadedTaskController.ExceptionHandler exceptionHandler = new ThreadedTaskController.ExceptionHandler() { public void handleException(Exception ex) { if (!(ex instanceof InterruptedRecorderException)) { if (ex instanceof RecorderException) { String message = preferences.getLocalizedString( HomeController.class, "exportToOBJError", objName); getView().showError(message); } else { ex.printStackTrace(); } } } }; new ThreadedTaskController(exportToObjTask, this.preferences.getLocalizedString(HomeController.class, "exportToOBJMessage"), exceptionHandler, this.preferences, this.viewFactory).executeTask(getView()); } }
}
and then I changed the HomePane.java and especially private static class OBJExporter
private static class OBJExporter { public static void exportHomeToFile(Home home, String objFile, String header) throws RecorderException { OBJWriter writer = null; boolean exportInterrupted = false; try { writer = new OBJWriter(objFile, header, -1); // System.out.printf(objFile + "\n"); if (objFile.equals("./My_Home/Room.obj")) { System.out.printf(objFile + "\n"); List<Selectable> emptySelection = Collections.emptyList(); home.setSelectedItems(emptySelection); if (home.getWalls().size() > 0) { // Create a not alive new ground to be able to explore its coordinates without setting capabilities Rectangle2D homeBounds = getExportedHomeBounds(home); Ground3D groundNode = new Ground3D(home, (float)homeBounds.getX(), (float)homeBounds.getY(), (float)homeBounds.getWidth(), (float)homeBounds.getHeight(), true); writer.writeNode(groundNode, "ground"); } }
// Write 3D walls int i;
// The first time, we want to export the only the walls and the room if (objFile.equals("./My_Home/Room.obj")) { i = 0; System.out.printf("Bhka sto walls\n"); System.out.printf(objFile + "\n"); for (Wall wall : home.getWalls()) { // Create a not alive new wall to be able to explore its coordinates without setting capabilities Wall3D wallNode = new Wall3D(wall, home, true, true); writer.writeNode(wallNode, "wall_" + ++i); }
// Write 3D rooms i = 0; for (Room room : home.getRooms()) { System.out.printf("Bhka sto Room\n"); // Create a not alive new room to be able to explore its coordinates without setting capabilities Room3D roomNode = new Room3D(room, home, false, true, true); writer.writeNode(roomNode, "room_" + ++i); } }
i = 0; System.out.printf(objFile + "\n"); if (!objFile.equals("./My_Home/Room.obj")) { System.out.printf("Bhka sto Furniture1\n"); //Write 3D furniture for (HomePieceOfFurniture piece : home.getFurniture()) { if (piece.isVisible() && objFile.equals("." + File.separator + "My_Home" + File.separator + piece.getName() + ".obj")) { System.out.printf("Bhka sto Furniture2\n"); // System.out.printf(objFile + "\n"); // Create a not alive new piece to be able to explore its coordinates without setting capabilities // I set as home = null HomePieceOfFurniture3D pieceNode = new HomePieceOfFurniture3D(piece, home, true, true); writer.writeNode(pieceNode); } } } } catch (InterruptedIOException ex) { exportInterrupted = true; throw new InterruptedRecorderException("Export to " + objFile + " interrupted"); } catch (IOException ex) { throw new RecorderException("Couldn't export to OBJ in " + objFile, ex); } finally { if (writer != null) {
try { writer.close(); // Delete the file if exporting is interrupted if (exportInterrupted) { new File(objFile).delete(); } } catch (IOException ex) { throw new RecorderException("Couldn't export to OBJ in " + objFile, ex); } } } }

Re: How to export to .obj all furniture seperately.
hello I used the last code you posted and yes, everything is exported seperately but all the .obj are in blank, only with a header and i am confused about it, are you sure this code work allright???, please i need a solution.
