Not having time to write a 3-D viewer myself, I have been using ISurface to view
some surface data. I have successfully texture-mapped data onto the surface and
added a second, semi-transparent surface.
Now to my questions and problems. This is IDL 6.1 on OS X 10.4.1.
1. I would like to add a title within the plot window, not just in the title
bar of the window. Clicking on the text annotation tool gets me a text-insert
cursor, but typing produces no text. (The straight line tool does not work, but
the other drawing tools do.) In any case, I would prefer to add text
programmatically, not interactively. (Text that does not rotate with the 3-D
model.) Is there a simple way to do that?
2. When I print, the graphic appears with a green background, not white as on
the screen. The surface itself is draw in solid black, and the texture map is
about half the size of the surface. That is, the texture map no longer lines up
with the surface. This is printing to an HP Color LaserJet PS. Any advice?
The graphic is also not scaled to the page. Is there some implicit dpi
conversion going on?
3. Is there any way to capture the window in a bitmap (e.g., TVRD)? Preferably
programmatically.
Sorry for the elementary questions. I don't find the docs to be very helpful.
