WW needs more *cowbell*.

Interestly enough,, that skit was on TV the other day.

Hi,
I did not find the post where what_nick offered a reward for animating a car over the Golden Gate Bridge, so I'll post there :
i haven't the car, but someone told me an imperial shuttle was heading to Toulouse, France
He recorded a short sequence (flash, 8.6 Mb): http://www.ige.fr/3d/WW/MoveYourX/MoveYourX.en.php

I used a quickly made plugin to do this. It's not really finished, but I'm not sure i'll have time to polish it. Maybe i'll give the code "as is"...

[TomServo]

Wow, that is pretty damn cool

[withak]

Nice.

A model animator plugin could just be the movie recorder with the code that moves/orients the camera replaced with code that moves/orients the model.

[jp09]

Yes, Withak, that's it !
Except that you have to change some things : you may want the model to do things the camera cannot, for example heading upwards. But basically, that's the idea. for the moment, I did it very basci, and i'm not sure i'll have time to improve it. But if someone wants the code....


By the way, i noticed an overflow risk for the Z value (float), l. 120 (aprox.) : drawArgs.device.Transform.World *= Matrix.Translation(0,0,(float)drawArgs.W orldCamera.WorldRadius + (currentElevation * Convert.ToInt16(isElevationRelative2Grou nd) + Altitude)*vertExaggeration);
Multiplying the currentElevation by vertExaggeration can lead to float overflow, that has to be managed. The basic solution I porpose is :
float MyZ;
if ( drawArgs.WorldCamera.WorldRadius + (currentElevation * Convert.ToInt16(isElevationRelative2Grou nd) + Altitude)*vertExaggeration > float.MaxValue)
MyZ = float.MaxValue;
else
MyZ = (float)drawArgs.WorldCamera.WorldRadius + (currentElevation * Convert.ToInt16(isElevationRelative2Grou nd) + Altitude)*vertExaggeration;
drawArgs.device.Transform.World *= Matrix.Translation(0,0,MyZ);

A full .cs file will be handier for the merge. How would you like the movemensts coded into the model via worldwind XML ? Suggestions are welcome otherwise i am suggesting a simple lat,lon,alt + orientation list instead of a single position.

[jp09]

The movements, xia XML ? Wow, didn't think about it...
I was more thinking of a plugin, just like movie recorder (it's possible to use both at the same time).
what i was beginning to do is just as withak said, starting from the movie recorder basis (Mashi, where are you ?! Can't you come back I miss you !!! ;o)
And customizing to model behaviour : i kept the same sc scripts as a basis (sequence of WW uri), because it was easy to generate, copy-pasting positions in WW (but a linear path, shapefile-like would be great for further use), with a separate altitude control, orientation being customisable just as offset, but moderated by direction (set by the path way). and maybe the possibility to attach the camera to the object, just in order to be able to follow the object
I believe it would not represent much work to do it. I may contribute, but not much, as I'm doing it partly on working time.
A possibility to bind the model's displacement with the movie recorder would be great to generate nice movies, but i don't see exactly how it should work...

Okay, I'm ready to take the dive. What file am I looking for when the UI prompts for a plugin file to browse to? I checked the Satellite Tracker checkbox but I don't know the type nor the name of the file that I am supposed to enter.

Assuming you're trying to hit the "Install" button, you don't have to - if it's in the list, it's already installed. There should be a Satellite Tracker item in the Layer Manager (assuming you've loaded it) where you can check which Satellites you'd like displayed.
