Hello all,
I am new to the opendx software, and I am having trouble with glyphs. I
am trying to plot glyphs of a vector field and I have several questions:
1) I keep running out of memory. I changed the type of glyph, which
helped, but I would like to know how to plot only every tenth position or
so.
If your data is on a regular grid, just use Reduce. If it is
scattered data, then you will have to come up with some other
solution.
2) I would like to use the compute module (or any module which works) to
take the length of each vector in the field and output a scalar field.
Run your data through Compute and use the expression: mag(a)
3) If (2) can be accomplished, I would like to make the autoglyphs plot
vectors based on magnitude.
Not quite sure what you mean here. Once you have the magnitude, it is
a single number with no direction. How would you know which direction
for your vectors to point? Or is what your asking that you want them
all normalized to length 1?
David
Thanks in advance,
