Hi AC3D plugin users :-) Recently we've had a few submissions of modifications to the ac3d plugin that try to fix texture repeat/clamping behaviour or their own sets of models that they encounter. The problem is that we now have multiple interpretations of what the ac3d plugin should do w.r.t texture repeat/clamping and these conflict, apply one patch and your fix models from source A, but break models from source B, apply another patch and your fix the models B, but break models A. Arggg.....
So what I'd like to properly resolve this matter. Ideally online descriptions of the format would answer this once and for all: http://www.inivis.com/ac3d/man/ac3dfileformat.html But the following: *texrep %f %f Optional - default 1.0,1.0 . The texture repeat values for the tiling of a texture on an object's surfaces. But it doesn't really say anything about the how the texture wrap modes map to this, if at all. And here lies the problem, the ac3d format doesn't really tell us enough about what OpenGL state to set for textures, one has to guess at what the settings are in ac3d and how they relate to items like texrep, or perhaps there are extra docs hidden away that provide the definitive settings for it. On the ac3d website's sources page it does have an example loader/viewer, perhaps it might be definitive? http://www.inivis.com/resources.html I suggest that we collect together a set of .ac files that demonstrate models where texture repeat is certainly intended and also models where clamp wrapped modes are intended. The mailing list has a limit of 300k per post, so if you can keep your post underneath this then you could post them here, but it'd be better if you can post them online for others to download and test. It'd be great if you could also provide screenshot of how the models should looked if perfectly rendered. Thanks in advance, Robert. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
