Hi!
My problem is, I'm sure for you experts its very simple, but I can't find my
way out...
I use three buttons to control the rotation of an object (rotX, rotY, rotZ).
First it works fine, but after some "Button-Clicks" the object disappears.
Why??
Thanks
Norbert
sourcecode:
case ROTATE_Y:
trans.getRotationScale(getMatrix);
Matrix3d yMatrix = new Matrix3d(1.0, 0.0, 0.0, 0.0, 1.0,
0.0, 0.0, 0.0, 1.0);
yMatrix.rotY(Math.PI/4.0);
yMatrix.mul(getMatrix);
trans.setRotation(yMatrix);
trans.getRotationScale(aktMatrix);
transformGroup.setTransform(trans);
break;
case ROTATE_Z:
trans.getRotationScale(getMatrix);
Matrix3d zMatrix = new Matrix3d(1.0, 0.0, 0.0, 0.0, 1.0,
0.0, 0.0, 0.0, 1.0);
zMatrix.rotZ(Math.PI/4.0);
zMatrix.mul(getMatrix);
trans.setRotation(zMatrix);
trans.getRotationScale(aktMatrix);
transformGroup.setTransform(trans);
break;
case ROTATE_X:
trans.getRotationScale(getMatrix);
Matrix3d xMatrix = new Matrix3d(1.0, 0.0, 0.0, 0.0, 1.0,
0.0, 0.0, 0.0, 1.0);
xMatrix.rotX( Math.PI/4.0);
xMatrix.mul(getMatrix);
trans.setRotation(xMatrix);
trans.getRotationScale(aktMatrix);
transformGroup.setTransform(trans);
