7
8 - Two DataCollector instances needs to be created when two active scalars
9 are read from the same file.
10
11 - setScalarRange() and generateCotours() must be supplied with the same range
12 in order for the colors to turn out correctly when contouring is performed.
13
14 - setPlaneToXY(), setPlaneToXZ() or setPlaneToYZ() needs to be executed
15 whenever a plane cut is performed before a plane can be rendered correctly.
16
17 - If a surface map and legend is created, both must have the the same scalar
18 range. For instance, if the surface map's scalar range is set between 2 and
19 4, the same must apply to the scalar bar's scalar range. Otherwise, the
20 colors of the scalar bar and surface map will not be sync.
21
22 - Movie will create a temporary file called 'make_movie' and will delete it
23 once the movie has been generated if no parameter file name was specified.
24
25 - To modify the parameter_file (i.e. change frames/second or codec), one needs
26 to save the parameter file (by supplying a name when creating the movie
27 instance) and run it manually using the 'ppmtompeg' command.
28
29 - Movies cannot be generated from post script (.ps) files.
30
31 - .iv (open inventor) and .wrl (VRML) files does not support multiple
32 viewports.
33
34 - .iv files do suffer from some lighting problems when generated by VTK.
35
36 - On occasions, an inaccurate object may be rendered from cell data
37 even after conversion. As such, it may be a good idea to use escript
38 interpolation to get the node data.
