Frequently Asked Questions
- I have a function and want to compute its level set. How do
I get my function added to the list of models that Pisces knows about?
- You will have to write a C file containing the definition of
your function, and then compile this model into Pisces. This
process is explained in the documentation section on
installing a new model into Pisces.
- I'm not comfortable programming in C. Can't I just type my
function into a parser?
- Pisces does not yet have a parser. However, you do not have to be
fluent in C in order to
install a new model! We provide templates
for you and complete line-by-line instructions.
- I've computed a curve and can see it in the view window. But when I use
the postscript panel to print the curve, it looks smaller (or larger)
than it looks in the view window. Why?
- The postscript panel uses the current
bounding box to determine
in what region to plot the level curve. The view window, on
the other hand, has its own independent box, called the
To insure that the level curve displayed by the postscript panel is
the same as that in the view window, try choosing the option
Actions->Viewport->BBox from the menu-bar
on the view window.
- How can I use the postscript panel to print directly to a printer?
- This option is not currently available.
- I used the Animation Panel to animate a family of functions, but
only got one level set. Why?
- If your parameter ranges between two integer values (say, from 0 to 1),
then you need to explicitly use decimal points (say, 0.0 and 1.0)
in order to prevent Pisces from using integer division instead
of floating point division.
- Are there any "keyboard shortcuts" to Pisces? That is,
can I open panels or clear data without using the mouse?
- Not at the present time.
