Can Fortran be used to create a video of changing arrays?

Click For Summary
SUMMARY

Fortran can be utilized to create a video representation of changing arrays by writing the arrays to a text or data file. Users have encountered challenges with VMD for importing these files, suggesting that alternative methods may be necessary. A practical approach involves using terminal commands to display the arrays, employing ANSI screen codes to clear the display between snapshots. Implementing a for loop to control the display timing and array size variations from 10x10 to 100x100 is essential for effective visualization.

PREREQUISITES
  • Familiarity with Fortran programming and array manipulation
  • Understanding of ANSI escape codes for terminal control
  • Basic knowledge of video recording software or terminal screen capture tools
  • Experience with file I/O operations in Fortran
NEXT STEPS
  • Research terminal screen recording tools compatible with Fortran output
  • Explore advanced Fortran array handling techniques for dynamic sizing
  • Learn about ANSI escape codes for effective terminal display management
  • Investigate video editing software to compile snapshots into a cohesive video
USEFUL FOR

This discussion is beneficial for Fortran developers, data visualization specialists, and anyone interested in creating dynamic visual representations of array data in terminal environments.

Hi, using Fortran that writes a large amount of arrays to a text/dat file.

Is there some kind of software where I can create a video of these arrays changing from beginning to end?

I've tried using VMD, but cannot get dat/text files working on it.

Any input will be appreciated.

What is the size of the arrays?

It seems you could write them the terminal screen and blank the screen between snapshots to show them changing in place.
 
I need to change the size of the arrays each time I run the programme but they vary from 10x10 to 100x100.

Will I need to snapshot the screen manually? I can have over 100 arrays written to the file and it'll take a while to screen shot each one manually.
 
You could just record the video output depending on the graphics card you have.
 
Okay thanks and I'd need to do this in the terminal, is there a way of recording each array snapshot from a dat/text file?
 
I would use a for loop to control calculation and then display and then sleep for a second or less and then repeat.

Prior to each snapshot display I'd clear the screen using an ANSI screen code printed to the screen.
