I work in the aesa of visualization and have been using VRML as a way of
sending results
from the visualization process across the WWW. This requires information about
the visualization
process to be sent with it such as values used in the viz process and colour
legends to allow
the mapping of colour back to values. It is very important for this information
to be viewed
alongside the object and for it not to move when the user changes camera
position.
I am currently using a 'feature' of Inventor which is unspecified in the
current VRML spec which
I described in an earlier posting ('Static objects in VRML Scenes' but which
received little attention).
This feature wouldn't be especially computationally expensive to implement,
having rendered the stationary
bits once, they could simply be rendered on top each frame update. This feature
is important for
the scientific vizualization community and I feel that to ignore it would mean
we would have to cesate
non standard VRML scenes and distribute our own browser to be able to view it
correctly. This is not at
all in the spirit of VRML and not a road I wish to go down.
I would propose extending the above node to allow the original rendering of the
objects beneath it
(yes objects, its not just text) to remain constant after any subsequent camera
change.
