MATLAB Central Newsreader - resource intensive in PDF created from ezmesh

resource intensive in PDF created from ezmesh

Hi All,
I have been using ezmesh to generate 3-D plane plots and
have come to a problem when importing them into my thesis.
The PDF generated from the figure (e.g. ezmesh('2x+3y+4', [1
50 1 50])) gives a very high CPU load when viewing it in all
PDF viewers I tried(Acrobat, Kpdf etc).

Is it because the vector format is really complicated for
the planes, or is there other better/easy alternatives? SVG
doesn't seems to be supported at all in matlab unfortunately!

While the PDF is obviously working, I really don't want to
impose a mandatory coffee break whenever other people open
the PDF waiting for 50-100 of figures to be rendered!

Thanks for all input,
Abe

You're getting something like 3,600 polygons (plus edges) for
each figure. That's a lot more than you would typically see in
a figure in a PDF file. Your choices are to lower the resolution
or save it in a raster format. When the number of objects is
large, a high res raster format can sometimes actually be a
better choice than a vector format.

Ah, that's right. I tried to use less polygons and it's
significantly better... thanks...
just realized my topic doesn't make much sense haha :)
