Hi All, I'd like to pick your collective brains for a moment in regards to search paths for files within OSG. I'm currently working on the 3DS plugin for OSG, looking at a little problem. The scenario is as follows.
I have a 3DS file whose material table references a texture. When this model was created the texture resided in the same directory as the model, and hence no path information was stored - at least I guess that's why there is no path information for the texture referenced. Now when I want to load this model, the 3DS loader tries to locate the texture in the directory that the model resides in - using the findfileindirectory function - but as the texture is no longer in this directory, the function fails to find the file, and the 3DS reader decides not to put a texture on the geometry. Now, the thing is, I do know where the texture is relative to the model. Its in a parallel directory. In fact, if I ignore the result of the find file, and merely just try and load the image, my readfilecallback handler amends the path to the file, and the image loads. So, what I was wondering was whether there already exists a way by which I can "direct" the findfileindirectory function to take account of a custom search algorithm? I've had a look and I can't spot one, but wondered if others might know differently? On the assumption that no such methodology exists, my thoughts were that I could amend the existing function to call a custom defined function on the user supplied readfilecallback - if one has been supplied - in the event where the readfileindirectory function has failed. Any thoughts ? Thanks for any assistance/comments. Kind regards, Neil. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
