I wrote a Python script to generate the frames then composed the images in Blender. I’ll put some effort to clean up the script and will share it when I get some free time…

Hi,

Sorry for the late reply - I’ve been down with the flu.

The runners parameter just specifies a bunch of points where the trail should end - they correspond to the bright doors on the video. They do not generate a sequence of images. If you want a sequence, you need to run the script multiple times, each time with the runners moved a few points ahead.

It’s a bit tricky. However, I have written another tool that can be help generate any kind of movie - you can check it here:

The easiest way to make an animation is to project the GPS data, export it to X3D format, load it in any 3D animation tool (like Blender, free) then animate any way you want:

The visualization in the video was done with Blender (freeware 3D modeling tool). GPSMash was used to load GPS tracks, clean-up the data, and combine them into a single .X3D file, suitable for 3D modeling.

RM87: Thanks for the information. I’ve tested it only with GPS data from my GPS device and from a friend’s, so this kind of information is exactly what I am looking for.

Can you send me a sample GPX? If you can e-mail it to me at avtanski at gmail dot com, I would be very grateful - with some luck I’ll be able to fix it immediately.

I just got a sample file without the tag and updated the script accordingly to handle it. Alv shouldn't have any problems anymore.

Hi Alv,

Thanks for the debugging - if you can mail me a short segment of a GPX file, this will be great. All I have here is GPX produced by my Garmin eTrex Vista Cx.

Skorasaurus' problem turned out to be different - he assumed that the script will traverse the subfolders of the folder he specified recursively, searching for scripts - it doesn't yet. When I have some free time I'll add this.

Regards,

You mean like this one - http://youtu.be/b_5IcRVIL-w ? :-) (Don't forget to turn on the audio.)

Can you send me a sample GPX file?

UPDATE: Thanks for the feedback. I updated the README.TXT to list the correct parameter (SRCDIR instead of INPUT) and included in the zip file on the site a sample script that uses ImageMagick to produce the halo effect.

Hello. Yes, I used ImageMagick - to produce the fuzzy glow effect. I merged the video from the images using VirtualDub.

Regarding the INPUT parameter not working - oops, my bad. The parameter is actually "SRCDIR". I'll update the README.TXT. Thanks for the tip.
