Hello,
I made a simple app with a simpleUniverse. After testing it and using
picking (worked fine).
I decided to implement the real app. The real app has to be in Ortho
projection and have tranformations on the viewbranch.
So, I implemented the a class extending virtualuniverse. I did
everything "by the book" I think and everything worked fine as for the
visual aspect, object showed up in the right place and the view was
right.
Now, I'm trying to use pickcanvas but it doesn't work at all :(
I've search a lot on the web and I already saw that there some kind of
problem with the pickcanvas pickshape for the customized
virtualuniverse.
In fact, the PickShape orign point, direction and start point don't
seem to make any sense at all.
(my objects have about 100 of size and the camera is ver faraway, and
the pickshape point is about (-0.07767107179733918,
-0.2967893129673346, 0.4174332443807395) although it changes - though I
don't understand how and why)
My universe has only a Locale. A world branch where I have my objects
and a view branch with my viewplataform and where I apply my
tranformgroup to change the camera point of view.
I use...
projection2.ortho(0, _width, 0, _height, -BACK_CLIP_DISTANCE,
BACK_CLIP_DISTANCE);
Transform3D cameratransf= new Transform3D();
this.getTransformGroup().getTransform(cameratransf);
projection2.mul(cameratransf);
view.setLeftProjection(projection2);
.... to have a ortho projection.
Any tips.. plz ?? :D
Thanks!
