[Opensim-users] Assets 101

[jon cundill]

Hi
Just knocked together a quick and dirty prototype for this, and using the
Terrain Upload/ Download for OAR files actually works quite well.

- Noticed Limitations

Viewer needs you to have .raw on the end of the filename. So you end up
downloading and uploading files named house.oar.raw rather than house.oar.

Maybe the Hippo Viewer people could do something about this if this goes
further.

It is slow, and little feedback is given to the user until it has completed,
so the 2.4 Mb house from the Free Assets page takes around 4 mins to upload
or download on a localhost standalone.

I have regions with 30Mb oar files - that would take nearly half an hour to
transfer, probalby longer across the internet.

You can probably send Estate Messages with some progress indication to
alleviate this.

As well as OAR files, this technique can also probably be used to
upload/download R32 or BMP type terrain file formats instead of LLRAW ones -
that might be useful.

If there is interest in pursuing this, and unless someone beats me to it,
I'll tidy up the code and submit a patch for review
