[Repast-developer] RepastJ: Two VectorDisplays possible?

[Pimin K. K. <spa...@gm...>]

Dear All,

I have to types of objects that i want to visualize in RepastJ 3.
object A (human agent) implements Drawable, the object B (road
segment)implements NonGridDrawable.

To visualize objects A, I use a Multi2DGrid/MultiObject2DDisplay combo,
To visualize objects B, I have used a VectorSpace/VectorDisplay combo.

My problem is 1) getX() for Drawable is in grid coordinates, while
getX() for NonGridDrawable is in screen coordinates. What I would like
is objects A and B to be displayed on top of each other (each have
geo-coordinates that a "in sync").

I have a running temp solution that uses a RasterSpace/Value2DDisplay
to display the roads in a cellular fashion, but this gives a lo-res
image of the road-segments, and is obviously not what i want.

Question 1: Would you recommend using something like the
OpenMapDisplay, and reimplementing the agents?

Question 2: Would you recommend that I implement a custom space for my agents?

Question 3: I HAVE tried using a vector space for both the agents and
the roads(both implementing NonGridDrawable), but for some reason my
Repast will only displays the roads, and not the agents. Should this
approach be possible, or is it just not possible to use two
VectorDisplays?

Any suggestions would be much appreciated.

By the way, running repast simulations on the web with Java Web Start
is really cool. I've made a small testcase at
