Well, I don't know anything about DirectX, but I may have to learn. We have some contractors doing some coding work for us, but pulling one of them off of a project to look at this may or may not happen. I will probably just have to try to follow the WMS fix example and see it it can be applied to the shapefile loader.

V1.4 does a lot better job of loading KML files, at least as far as speed is concerned. For some reason it is much faster. We use that to display aircraft plots. I'd love to have that, but we also use the shapefiles to display theoretical radar coverages. right now anywhere that has overlapping coverages looks like a black blob. Until that gets fixed we will have to stay with the current version.

Hey I found a workaround.

You can specify opacity via the color in the xml instead of the layer properties.

Code:

    <PolygonColor>
      <Red>255</Red>
      <Green>0</Green>
      <Blue>50</Blue>
      <Alpha>150</Alpha>
    </PolygonColor>

Good deal! That should work nicely. I'll give it a try first thing tomorrow...
Thanks!

The only drawback would be that you can't change opacity set this way from the gui, you would have to edit the alpha values in the xml and reload.

James_In_Utah · 02-11-2007, 10:49 PM

Using the current loader, there doesn't seem to be any way to edit the shapes anyway. If I want to change the color, I edit the xml, and then reload the whole earth. It would be great if the whole shapefile layer could be reloaded without restarting WW or reloading the earth.

If the shapefile layer is second in the tree from the Layer Manager, if you turn that off and on it will that reload it? I'm finding that with another few renderable objects...

withak · 02-12-2007, 01:38 AM

It doesn't re-read the xml when you do that.

Chade · 02-12-2007, 05:08 AM

Read the post, dammit Chade. Editing the xml! >.<

Anyway, wouldn't deleting and loading the xml (again) be faster than restarting WW or reloading Earth...?

There doesn't seem to be a good way to unload the shapefiles currently. I actually added logic that allowed me to "Delete All" entries under a layer in the layer manager, and then I could use the shapefile loader dialog to reload the xml files, but it had lots of bugs. Once V1.4 is out I will probably try migrating my changes forward.

A File -> Load... dialog will almost certainly be in 1.4.1. The code was there in 1.4 but it wasn't tested enough. Right-click -> Delete... does works in 1.4. Unfortunately it doesn't permanently delete shapefile layers because the loader doesn't include the xml filename in the the RO metadata like it does for regular layer; so all it can do is remove them from the LM until you restart.
