FieldAnimation in a nutshell¶

To use FieldAnimation in a real PyOpenGL application simply:

create a FieldAnimation instance

call its draw method in the main rendering loop

An example application is included in the package at fieldanimation.examples.app. This module can be executed as a script:

app¶

Field Animation example. Press “G” to display the GUI while running.

usage: app [-h] [-f]
           [-c {epole,Duffing's equation,Structurally stable system,Transcritical bifurcation,Reaction diffusion,Positive invariant set,Spiral ccw,Spiral cw,wind,gmod}]
           [-p] [-u] [-g] [-i IMAGE]

-h, --help¶: show this help message and exit

-f, --draw_field¶: Draw vector field as background image

-c {epole,Duffing's equation,Structurally stable system,Transcritical bifurcation,Reaction diffusion,Positive invariant set,Spiral ccw,Spiral cw,wind,gmod}, --choose {epole,Duffing's equation,Structurally stable system,Transcritical bifurcation,Reaction diffusion,Positive invariant set,Spiral ccw,Spiral cw,wind,gmod}¶: Choose field to animate

-p, --fps¶: Count Frames Per Second

-u, --use-fragment¶: Use fragment instead of compute shader

-g, --gui¶: Add gui control window

-i <image>, --image <image>¶: Load image as background texture
