Title: Object rotation
Post by: penprakash on July 30, 2013, 01:01:34 pm

Hi,

 i have added the code to display object in jpct-ae

 model.align(camera)

 when i move the direction the whole object is moving / rotated. How to place the object in static position with camera?

align() only affects rotations, not translations. If you want the object to stay in front of the camera, try something like this (untested, might contain errors):

Code: [Select]

SimpleVector pos=camera.getPosition();
SimpleVector x=camera.getZAxis();
x.scalarMul(50);
pos.add(x);
obj.clearTranslation();
obj.translate(pos);
obj.align(camera);
