[FieldTrip] ft_plot_topo3d crash

[Roemer van der Meij]

Hi Julian,

As a sort of last-resort workaround:
If you're not using it for publication quality figures, but for e.g. 
databrowsing, you could create a set of nasty looking figures by setting 
the renderer to zbuffer, instead of opengl. You can do it while creating 
a fig by figure('renderer','zbuffer'). Zbuffer doesn't work with 
transparency, which is essential for masking. If you don't use masking, 
it might actually look fine I think, but not entirely sure. At least you 
can get some workable figures now, maybe create publication quality on a 
different machine?

Hope it's a bit useful,

Cheers,
Roemer
