i tried pose estimation for my augmeted reality.  i used solvepnp opencv
this is the code
Code: [Select]
TargetPoint = new MatOfPoint3f();
TargetPoint.alloc(4);

return result;
and i rotate my model using
object.setRotationMatrix(result); but the model rotate all over place

and i tried to rotate camera using
camera.setBack(result); i got result like object rotate.

rotation gone wild all over screen. and blinking when rotate.

is there anyone know where my problem?

what should i do if i want to export multiple mesh ogre to bones?

"jmeOgre2Bones -out bone.bones -in mes1.xml mesh2.xml" like this giving error number of vertices differ

my model in 1 blender file

you procedural animation saved me. my finger now can move.

can i select a mesh from animated group? example i want to select my fingertip. can i select fingertip mesh?

thank you. i already can move my finger to my desire location. Can but parent mesh not follow the object rotation. how can i calculate the rotation to make the parent mesh like follow the child? and is the skeleton helper can move the joint and follow by the parent joint?

So how i can move the joint? Ex: i want to move my joint to (240,200,10) this is my marker position.

Code: [Select]
   Joint pointing  = currentPose.getSkeleton().getJoint(15);
final Joint parentJoint = currentPose.getSkeleton().getJoint(pointing.getParentIndex());
final Matrix global= new Matrix(pointing.getBindPose());
global.translate(x,y,z);
global.matMul(parentJoint.getInverseBindPose());
currentPose.getLocal(pointing.getIndex()).setTo(global);
currentPose.updateTransforms();
skeletonDebugger.update(currentPose);
global.translate giving different position from object3d.translate()

is matrix translate different form object 3d translate?
when i used matrix translate and object3d translate with same value, giving different output.
can i cast matrix to object 3d? because i want to make augmented reality, that my object translate where my marker position.

in the picture my marker is the white circle. if i use matrix translate, i cant move to the white circle.
but if i use .obj file with object3d translate , i can move to white circle.

any idea?

i already solved the model . And now i can tranlate and rotate the skeleton with this code.

Code: [Select]
Joint pointing  = currentPose.getSkeleton().getJoint(15);
final Joint parentJoint = currentPose.getSkeleton().getJoint(pointing.getParentIndex());
final Matrix global= new Matrix(pointing.getBindPose());
global.translate(10,10,10)
global.matMul(parentJoint.getInverseBindPose());
currentPose.getLocal(pointing.getIndex()).setTo(global);
currentPose.updateTransforms();
skeletonDebugger.update(currentPose);

the joint at index 15 stretch. but my mesh not. i want the parent joint following, like seymour neck in ProceduralAnimationSample.
how i can do like that? i don't know where the mistake, in the program or my model.

thank you. i followed ProseduralAnimationSample.java.
but my skeleton  and my mesh model not in same position.
my skeleton a bit lower form my mesh model.
in blender my model and my armature is okay.

i have bones file. i want to select 1 part of my file to rotate.
how i can get access to my bones joint?
how can  i cast animated group to animated 3d?
