about updateData

[j3d]

I have method UpdateMyData, where I use external data from another class for updating geom. I call it from another class. But the result is bad - only one surface updates. What is wrong from your point of view?

For clearness:

So, I call method:

1   2   3   4

... for(int s =0; s<ldr.listOfSurfaces.size();s++) sh3d.UpdateMyData(s, ldr.getCoordsFace(), ldr.getCoordsFaceXYZ()); view.renderOnce(); ...

The body of method is:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29   30   31   32   33   34   35   36   37   38   39   40   41   42   43   44   45   46   47   48   49

public void UpdateMyData(int getSurface, int[] getCoordsFace,int[][][] faces) { System.out.println("Updating data..."); final int TMPsurff/*getSurface*/ = getSurface; final int[] TMPgetCoordsFace = getCoordsFace; final int[][][]TMPfaces = faces; geom[TMPsurff].updateData(new GeometryUpdater() { public void updateData(Geometry geometry) { System.out.println("Surff is: " + TMPsurff+" "); //проходим через все фейсы for(int ff = 0; ff<(TMPgetCoordsFace[TMPsurff]); ff++){ //point geom[TMPsurff].setCoordinate((ff*3)+2, new Point3f( ((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][0])))[0], ((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][0])))[1], ((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][0])))[2])); geom[TMPsurff].setCoordinate((ff*3)+1, new Point3f( ((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][1])))[0], ((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][1])))[1], ((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][1])))[2])); geom[TMPsurff].setCoordinate((ff*3)+0, new Point3f( ((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][2])))[0], ((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][2])))[1], ((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][2])))[2])); } } }); } public void updateData(Geometry geometry) { // only for:The type shape3dcreator must implement the inherited abstract method GeometryUpdater.updateData(Geometry) }

Im not sure about how the update should/could be made but have you tried the GeomDataInterface for setting the floats in the geometry.
If you check this http://xith.org/tutes/GettingStarted/html/more_fun_with_textures.html tutorial you see how its done in that way.
Its updating textureCoordinates, but im sure it works for all geometry data, at least all that i have tried ( coordinates, colors ).

So i geuss that instead of doing this

//point
geom[TMPsurff].setCoordinate((ff*3)+2,
new Point3f(
((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][0])))[0],
((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][0])))[1],
((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][0])))[2]));

geom[TMPsurff].setCoordinate((ff*3)+1,...

geom[TMPsurff].setCoordinate((ff*3)+0,...
...

you could try doing this

//point
GeomDataInterface coords = ((GeometryArray)geom[TMPsurff]).getCoordinateData(0);
coords.setFloats((ff*3)+6,
((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][0])))[0],
((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][0])))[1],
((float[])(((ArrayList)listOfSurff.get(TMPsurff)).get(TMPfaces[TMPsurff][ff][0])))[2]);

coords.setFloats((ff*3)+3,...

coords.setFloats((ff*3)+0,...
...


Hope it works

It disfigures geometry.

I will try to look at Xith docs closely. But the main problem is: it updates ONLY the last geom, that was loaded thought I pass all geoms.
