Yes but View engine is fast enough for creating 2D and even some simple 3D
games so why not implement collisions? I cannot see into the guts of View
engine but this wouldn't be so hard to implement imo. It the face has in
options word 'sprite then each visible pixel(or pixel of user chosen
color(s))of this face will be checked during rendering... But maybe I'm
wrong and the problematics is more complicated.
Regarding event sensing: Few moths ago I had a chat with Carl about that
feature at link conference. Carl put this into bug database at /Link
developers server so I thought this will be solved in any future release...

Great!! Sometimes, I'm puzzled when building effect block ;-)

nice 3D demo isn't it? ;-)
try to use cursor arrows to rotate....works great...
then try '+' an '-' keys on the keypad...when you zoom "out of the bounds"
/View will crash...
I think it is due some problem during creating of image datatype itself.
Looks like when you create new image and draw out of bounds...looks like we
can "draw" into unallocated memory or so?
I have found out that rebol crashes when usually "fill" into negative
coordinates but this is not a rule...

You don't know legendary "circle" bug? ;-)
try this:
view layout [box with [effect: [draw [pen red fill-pen red circle 50x50
20]]]]

Why not elipses when you have done circle? I thought It's question of one

I will be very happy even with rotation without anti-aliasing :)
Anyway, thanks for your comment. It put more light into the situation about
the way of the next View...
Last question, when we can expect next release of /View? ;-)
