Thread: [Ogoglio-developers] rendering problem?

Hi Trevor,

I seem to have some problem with rendering.

I create a space and add the "Default Land".obj and mtl.

When I enter the space I get a question mark.

Any idea what I'm doing wrong?

Thanks,

Gal.

Hey, Gal.

The question mark model is used when the client either can't get the
obj data or can't parse the data it gets.  You can manually check that
the obj data is being served by opening the following URL in firefox:

http://<host and port>/og/account/<username>/template/<template
id>/geometry/data/0

For example:
http://example.com:8080/og/account/library/template/1/geometry/data/0

If you get a 404, then the server can't find the template data, either
because it wasn't uploaded or it wasn't stored.  Double check that the
obj file that you uploaded is in your media directory in a file named
templateGeometry-<template id>-0, for example templateGeometry-1-0 for
template 1.

If you don't get a 404 and you do get the obj data when you hit the
URL, then I'm not sure what's going on.  Try debugging (or adding some
println's to)  the SpaceClient to check that it's getting the data.

For what it's worth, using the current trunk I just created a template
and loaded defaultLand.obj and defaultLand.mtl into a template and
they rendered in a space.  So, it could be a local change you've made.
 Double check that in the template editor UI you're uploading the obj
into the "lod 0 .obj" field and the mtl file into the "resource"
field.

OK, got the bugger....

It seems that when sending the gif zipped the client throws an exception. For 
now I commented out the lines and peace is back :)

                //if ("gzip".equals(request.getHeader("Accept-encoding"))) {
                //    response.setHeader("Content-encoding", "gzip");
                //    StreamUtils.write(data, new 
GZIPOutputStream(response.getOutputStream()));
                //} else {
                    StreamUtils.write(data, response.getOutputStream());
                //}

You don't want to disable gzip compression completely, because obj
models are quite large if they're not compressed so load times are
slow and bandwidth charges are increased.

The default landscape model uses the Grid.gif as a texture.  Did you
upload that to the template or perhaps it's trying to gzip nothing?
On OS X and linux we don't get that far when a template resource
doesn't exist, but perhaps there's something different about XP?

Hey, Gal.

Please put a println in J3DRenderer.SpaceListener.userAdded(...) to
see if you're getting the same user added more than once.

Thanks,

Hi Trevor,

Sorry... false alarm. I was accessing my local ip 192.168 instead of the 
domain name. I still haven't figure this out yet :( .

Any way, all is working fine.

Thanks,

Gal.
