3D KML add height for display

[davidoesch]

Hi

as discussed with @gjn
ask c2c for support on how to make a plain kml line drawn or imported (only x y no z) in map.geo.admin.ch work in 3d view by adding on the fly alti information to it make it artificially clamp to ground ( or at least 2, above ground) as in map.wanderland

this is a workaround for
#3374
and
#3017

@oterral do you see a way to do that ?

[oterral]

Here an example of the Cesium hack for Polyline:

1. Click here
2. Drop the file (PatrouilledesGlaciersPOI.txt) in it
3. Go to 3d

You see a small line of 30m width because the 2d line was 30 pixel width

The idea would be to improve this hack if possible and do the same hack in ol3-cesium.

[davidoesch]

this is what we need...

any review on this approach by @gberaudo @gjn

• side effcts, limitation etc?

[oterral]

Just saw, if we get the corridor object. We can modify the width of the corridor on-the-fly

[davidoesch]

when do we have an ETA for this?

hi oli
Question, having wandern.ch working in 3D https://www.wandern.ch/ewalc/images/ewalk2/1200/geodata/geodata_de.xml
which changes do need be made?1 seems not to work cc @cedricmoullet

[oterral]

Just put <tessellate>1</tessellate> instead of <tessellate>0</tessellate> and it works

[davidoesch]

If did a find and replace of 0 to 1 but no success for the file above

[oterral]

That's what I did and it works

[oterral]

You can't load via GIST because it returns a bad-formed XML file with text at the beginning.

[oterral]

I make it work with another KML.

[oterral]

Remove the line in file:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<!--  Generator: OCAD Version 12.1.1  -->

[davidoesch]

did not change anything

[oterral]

Remove also the <script> tag in it.

[oterral]

@davidoesch it works without <script> tag, see

[oterral]

@davidoesch @gjn draw clamped to ground see

with openlayers/ol-cesium#437

[davidoesch]

When will this be in prod? next deploy?
