How to display all particles' Identifier?
« on: October 11, 2017, 12:52:11 PM »
Hi everyone´╝ü
    I  have some problems while using OVITO.
    1. how to display all particles' identifier on viewports?
    2. what's the utility of 'show up  to current time only' in trajectory display?
    3. how to visualize and output the animation of trajectories line as Figure 9 in Manul? I created trajectory lines according to the Manul,but just get some static lines on viewports?
    4. how to select particles of specific identifiers efficiently?
    Hope to get your replies!
    Thanks and best regards!
    Sunny

Dear Sunny,

1. Do you mean showing the IDs as labels next to each particle in the interactive viewports? That is not possible, sorry.

2./3. The option "Show up to current time" is what you need to produce animated trajectory lines. By default, OVITO shows static trajectory lines that reflect the motion paths of particles over the entire simulation from beginning to end (including the "future" part of the motion, so to say). If you activate this display option, however, OVITO will render the lines only up to the current position of the particle that is generating the trajectory line, leaving out the "future" part.

4. There are two places in OVITO where you can select particles by numeric ID: The Expression Select modifier allows you to create a dynamically updated selection of particles (based on IDs or other criteria). This selection set may be used as input to subsequent operations such as coloring the particles. The second tool in OVITO which allows you to select particles is the Particle inspection utility. This is only meant as an interactive inspection tool, which allows you to look at the properties of certain particles of interest. However, it doesn't provide a way to modify these particles.
