[Solved] Picking woes....

[Kashank]

Ok I've heard alot on the forum about this and I've searched but I can't seem to come across what I'm looking for. I found a forum topic where a guy was able to turn off picking within his select listener... however.


I have not included a select listener within mine. Is there specific code to turn off picking?

or even code that alows me to "select" and object without being able to move it?

Not sure what you are asking for... turn picking off for what? terrain, imagery layers, icons, surface shapes?

To be able to select an object, that object must have gone through the pick pass and registered at least a PickableObject with the DrawContext. Whether you just consider it 'selected' or handle some sort of dragging is the application choice.

I apologize.

I read that by turning picking off of polylines that it will increase the performance of the application.

I wasn't able to figure out how to turn off the picking for my polylines, but I saw that you can just go and do a

layer.setPickEnabled(false);

to turn off picking for the layer that the polylines were added to. But this didn't seem to help the performance at all.

I guess you are using terain following polylines with a renderable layer. Did you try SurfacePolyline in a SurfaceShapeLayer?

How many vertices do you try to render?

Nah I can't use terrain following. I need the elevation parameter for the polylines. So surfacepolyline's are out for me

ha ha the vertices are a little ridiculous.... somewhere around 70,000.

I'm not expecting to have it run perfect, cause I know it's gonna suffer performance issues. I just want to make sure I can make it run as good as possible. I've already dumbed down the polylines with these lines of code.

Polyline.setPathType(Polyline.RHUMB_LINE );
Polyline.setAntiAliasHint(Polyline.ANTIA LIAS_FASTEST);
Polyline.setNumSubsegments(0);
Polyline.setFollowTerrain(false);
Polyline.setLineWidth(1);
Polyline.setStippleFactor(0);

and that helped my performance ALOT.
