I used a different method to get teh color coding to work. :mrgreen:

1. Shaded Area Terrain

2. Line Terrain (In the real VSD, it's not shaded so I'm gunna' stick with this)

Image

I'll also replace the WAypoint IDs with Waypoint VNAV Altitudes and make lines across with the Waypoint IDs on top (like in the real one) :)

Did some more work on the VNAV Altitudes :D

Image

I'm done with that for now... Once we get a working lateral TCAS, we'll try to implement that in vertical mode. At the moment, the VSD is embedded into the 787's MFDs' NAV page (which explains the lateral navigation lines of code)... To generalize it, do I separate it with just the screen area? And, should I change all /controls/navigation props to /instrumentation/vsd :?:

Looking great!
What about the issues you mentioned (indexing, floating point)?
Do you still want me to look at the code?

Regarding generalization, I suggest the following:
  • use separate VSD specific property tree branches, otherwise people would inevitably need to adopt the same ND, too - right?
  • it should be possible to instantiate multiple VSDs at the same time, i.e. PF/PNF (copilot,captain)?
  • it would probably make sense to make some more settings configurable (such as horizontal range/vertical scale)?
  • changing those settings for one VSD shouldn't affect the other VSD, right?
  • the modified code I sent you, also put the sampling interval into a variable, this would allow listeners to be used, so that these variables can be easily updated (property tree)


BTW: TCAS -even in real life- is currently limited to vertical evasion maneuvers, lateral TCAS is work in progress: http://en.wikipedia.org/wiki/Traffic_co ... imitations

If you want me to take a look, you can either send me an archive containing the implemented aircraft/instrument, or just use a gitorious merge request so that I can pull your changes.

Thanks & all the best,

How do I do that exactly? I have git installed (using FG git too) and stuff and I know how to pull, but not to send a merge request.. As it is, what am I going to merge it to? The 787 (one I'm working on) doesn't even have a complete FDM, just systems, models and a temporary FDM. :oops:

And, If you could wait a day, (it's midnight here) I can separate the VSD from the rest of the ND and upload it (or if I find out how, then merge into git).

Merge requests are documented here: http://wiki.flightgear.org/Merge_request#Merge_requests

But, I suggest to do this only AFTER backing up all your important FG-related data, to ensure that you don't lose any data.

Finally, I found a way around the floating point issue! :D

I shoulda' thought of this before, all I did was replace the animations where the x.5 doesn't result with x.49999999999999.

Code: Select all
<animation>
      <type>textranslate</type>
      <object-name>elevation21.5</object-name>
      <property>/controls/navigation/vert-profile/nm21.49999999999999</property>
      <factor>0.00001115</factor>
     <axis>
        <x>0.0</x>
        <y>-1.0</y>
      </axis>
</animation>


Works now :)

Now, you don't have to be afraid of this anymore... just look at the VSD when you fly. :lol:

I guess we no longer can fly as we see fit (C-FIT). :wink: :lol:

Great work by the way (I've honestly only looked at your screen shots and read the topic though). :D 8)

(Addressing Hooray's question of whether we could pass cloud position between the cloud subsystem and wxradar)

The short answer is Yes. Unfortunately, it would require a bit of coding - at the moment we basically convert the cloud location into OSG-space and then forget about it.

I haven't looked at the wxradar code at all, but rather than making the cloud locations available to wxradar, it might in fact be easier for the wxradar to query the cloud information for a given span, convert that to OSG-space to pick up any collisions.

I'm not in a position to volunteer to do that right now though :(.
