Some refactoring, standalone draw3d viewers. [message #3884] Tue, 02 June 2009 23:13 Go to next message

Hi everyone,

just a quick pointer that I have refactored some gef3d and draw3d code.
I have created a new plugin called org.eclipse.draw3d.ui, which you
need to check out (from eclipse.org) in order to compile everything the
next time you update (if you are using SVN Head).

This was neccessary in order to support standalone draw3d viewers with
a working camera without duplicating lots of code. I will check in
another project containing the base classes and an example
implementation of such a viewer soon.

I hope I haven't broken anything - it seems to work fine on my system.

Miles: I will work on shapes after I finished the draw3d viewer. I will
add cones and cylinders first. Is there anything in particular that you
need?

Oh, and I have implemented the 3.5 Graphics methods, but will not
commit this until 3.5 is out. If you need patches against current SVN
for this, let me know.

Best regards
Kristian

Nice.. The whole IEditPart vs. IViewPart thing is really a relic at
this point. I find views to be much more suitable for a lot of stuff.

I just wrote one as well, but it's tied into all of the AGF pieces.
Found it really simple to do though. Unfortuntaly I don't have my CQs
for initial contributions in yet so I can't point to the code. But see
below..

For camera all I needed was to

CameraTool camera = new CameraTool();
getEditDomain().setActiveTool(camera);

Thanks for asking. :)

One thing that I'd like though I don't know if it would be useful for
anyone else is the ability to supply a 2D figure and then either rotate
it or

The obvious hacks are working just fine.. I'm away for a week or so, btw..

I forgot to finish my sentance!

...just place it on an x, y or z oriented plane. Of course we already
have Z :) But this would allow the simple creation of "cutouts".

As far as actual shapes go, for now I'm just using the LGWL primitives
which works but as the render context isn't passed in and based on your
previous comments that won't be a good solution for future.

It seems that spheres are expensive in 3D graphics! Hemispheres would
be really useful as well and regular polyhedra.

I would expect a new plugin called org.eclipse.draw3d.examples for that
purpose? You could move my viewer part demo from the gef3 examples to
that new plugin (or remove it, if it is only a duplicate).

No, the viewer base class should go into draw3d.ui I think. It's not an
example, but a base class that everyone can use to implement their
viewer.

Okay!
