Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
There is no specific hard-coded limit in the visualization, but I think what's happened is that you're hitting the limitations of round-off errors in the visualization code.
I have indeed reproduced your problem in all three of OpenGL, HepRepFile and RayTracerX.
I know from seeing some of your past research that you are engaged in very interesting problems at the DNA scale, so I very much would like to help find a solution. My guess is that the solution lies in changing Geant4's internal length unit from its usual mm to something more appropriate to your work. I understand that this is something that can be done, but I haven't done it myself. I'll try to get us some advice on this.
I understand that you have structures to visualize on the nm scale. What is the other end of the length scale that you need, that is, what are the largest structures that you need to visualize?
