Re: [opendx-users] FEA Grid Visulization
Glyph module supports a text glyph which displays the value of the data at its spatial location. Use carefully: a huge data set will generate a heck of a lot of text, which will then be unreadable unless you zoom way in. Think about ways to sample (like Sample) or otherwise constrain the area of interest (like Pick to select a cube, line, or position). Now, if you simply Mark(positions) and Glyph(text), you'd see the position vectors. If you don't already have a data component representing the position index, I'd probably use Inquire(items) (or other inquiries: see manual) to get the position count, then use that to drive Enumerate to make a list of 0..n-1, then Replace that into the field as position index, then Mark(position index) and Glyph. You probably have to add Options(dep, positions) to the output of Enumerate (prior to Replace) to make it behave like a proper data component.

Re: [opendx-users] FEA Grid Visulization
If by number the positions, you mean you want the number 1 to appear in the scene at the first position, 2 at the second, and so on, here's one way... To get n, Extract(positions) and feed to Inquire(items). Feed this to Enumerate to generate the integer list 1 .. n. Replace the data in the original field with this list. Send this to AutoGlyph; set the glyph type to text, and the ratio to 1.0. Color to taste. Cheers, Joel Jon Pitt wrote: Hi, I'm trying to visualize a grid generated by an FEA package.
