You can test almost all abilities of QwtPlot3D from within the
mesh2 example,
including:
- Colors, fonts, normal vectors, mouse handling etc.
- Grid and FEM data reading from files (in
data/*)
- Output to all pixmap formats supported by Qt
- Output to vector formats supported by gl2ps
- Plotting styles and resolution change on the fly
- Shading
The
example
demonstrates vector graphics output utilizing
gl2ps. That
means EPS, PS and PDF. See
here
for an
extensive discussion. gl2ps
uses optionally
zlib for
compression. This leads to
significant smaller EPS
& PDF output and is therefore recommended. The zlib switch in
qwtplot3d.pro turns compression on or off. The default setting is OFF
for Windows and ON for all other systems.
So, it would be a good idea to get this example project up and
running
