- #1347: Restructure vector_field module and add documentation
:class`~.VectorField` is renamed to
ArrowVectorFieldand a new class
VectorFieldis added as a superclass for
AnimatedStreamLinesis removed. It’s functionality is moved to
StreamLines. Added a lot of new options when working with vector fields.
ShowPassingFlashWithThinningStrokeWidthwas moved to the indication module.
- #1161: Upgrades to CoordinateSystem and graphing.
Breaking changes were introduced to
NumberLineAll the above now use lists to construct their ranges as opposed to explicitly defining these values. x_range has replaced x_min, x_max and defining the step is much easier with x_step –>
[x_min, x_max, x_step]. There were also many upgrades to these classes which improve their functionality and appearance.
NumberLineOldwas introduced to continue support for
GraphScene, although we are moving away from GraphScene and intend to deprecate it in a future release.
- #1013: Refactored the Command Line Interface to use Click instead of Argparse
This change breaks the CLI API to organize the structure of Manim Community’s commands, options, and arguments.
To be more in line with POSIX compliant CLI conventions, options for commands are given BEFORE their arguments. In Argparse:
manim basic.py -p -qlWith Click:
manim -p -ql basic.py
Although this is primarily a refactor and most of the common options are still there, some options have been added/removed. Use the
--helpoption, or simply run the command without providing options/arguments to view the help page with the full list of subcommands/options/arguments.
--frame_rateoption which allows for custom fps that don’t have to be integer (i.e. 29.97, 23.98, etc.). Users no longer have to specify the FPS from within a config file. Additionally, the
--webgl_renderer_fpsoption has been removed. Use
--rendereroption which you can use to select your choice of renderer (e.g.
--renderer=opengl). There are currently THREE renderers to choose from!
--background_coloroption. Reassigned the
Removed the deprecated render quality flags, in particular:
--soundoption. It lost support long ago with the removal of SoX.
