Re: [Meshlab-devel] quadric filters

[skunkwerk <sku...@gm...>]

could someone send me the minerva file as a collada?  maybe it won't crash
my machine that way.
i've tested the texture atlas on about 20 different models, and it worked
fine with all of them.  however, when a model has a lot of textures and I
have to increase the size of the texture atlas from the default, the
resulting model does not load the textures properly - i get this error in
meshlab:
QOpenGLPaintEngine: failed to create fragment programs
and the texture atlas image looks incorrect (has gaps in between, see
www.akbars.net/textureatlas.png)

Paolo, when you tried the minerva with the texture atlas, did you have to
increase the size of the atlas?  did you get the same error when loading the
saved file?
