Breaking changes

• #1521: Improve Animation docs

  • Improve documentation of the Animation class.

  • Unify the signature of get_all_mobjects. Now it always returns a sequence of Mobjects. This breaks using FadeTransform.get_all_mobjects as Group.

• #1470: Drop support for Python 3.6

  Manim won’t work on Python 3.6 anymore.

Highlights

• #1447: Added PolarPlane for polar coordinates.

• #1490: Added Polygram, rework the polygon inheritance tree, and add Star

  • Add Polygram, a generalized Polygon that allows for disconnected sets of edges.

  • Make Polygon inherit from Polygram.

  • Add regular_vertices()

  • Add RegularPolygram.

  • Make RegularPolygon inherit from RegularPolygram.

  • Add Star.

• #1462: OpenGL: Added Shader, Mesh, and FullScreenQuad

  Add Shader and Mesh objects

• #1418: Added project management commands

  • manim init - quickly sets up default files for a manim project.

  • manim new project - lets the user set project settings. It also creates the project inside a new folder of name <project_name>

  • manim new scene - used to quickly insert new scenes into files. If file name is not provided main.py is used as default.

Deprecated classes and functions

• #1598: Update examples to use Axes and deprecate GraphScene

  GraphScene has been deprecated and its functionality has been shifted to Axes. See the updated example gallery for sample usage.

• #1454: Fading module enhancements

  Moved functionality of all Fading classes to FadeIn and FadeOut. All other fading classes have been deprecated.

• #1375: Deleted the deprecated ShowCreation in favor of Create

New features

• #1566: Added the ability to add gridlines to a Rectangle

• #1548: Added ArcBrace, a subclass of Brace.

• #1559: Update VGroup to support item assignment (#1530)

  Support indexed item-assignment for VGroup

• #1518: Allow fading multiple Mobjects in one Animation

• #1422: Added override_animation() decorator

• #1504: Color module enhancements

  • Replaced BLUE_E with what was previously DARK_BLUE and removed DARK_BLUE

  • Added alias LIGHTER_GRAY for GRAY_A

  • Added PURE_RED, PURE_BLUE and renamed GREEN_SCREEN to PURE_GREEN

  • All gray colors are now also available using British spelling (including GREY_BROWN)

  • Replaced color example in the docs. It can now be used as a quick reference for all color names.

• #1272: Implement metaclass approach in geometry module to make mobjects compatible with cairo and opengl rendering

• #1404: Added two deprecation decorators

  Added two function decorators deprecated and deprecated_params as a consistent way of deprecating code.

Enhancements

• #1572: OpenGL compatibility via metaclass: TracedPath, ParametricFunction, Brace, VGroup

• #1472: Porting methods from GraphScene to CoordinateSystem

• #1589: OpenGL compatibility via metaclass: ValueTracker

• #1564: Add extra notes for TeX compilation errors

• #1584: Added a check for 0 in round_corners()

• #1586: Add OpenGLMobject support to all isinstance occurrences

  This PR increases the support for OpenGL in the remaining animation classes and in other places where appropriate.

• #1577: Added new metaclass ConvertToOpenGL (replacing MetaVMobject), restore IntelliSense

• #1562: Improved VectorField’s Nudge Accuracy Per Step

  Implemented the Runge-Kutta algorithm in VectorField’s nudge function. This increases the accuracy as an object moves along a vector field. This also increases efficiency as the nudge function requires less loops to achieve accuracy than the previous implementation.

• #1480: Add logging info to tex errors

• #1567: Compatibility Fixes with ManimPango v0.3.0

  • ManimPango v0.3.0+ is required for Manim now.

• #1502: Added center parameter to Sphere and point parameter to Dot3D

• #1486: Update of rate_functions

  Changed the picture for the non standard rate functions.

• #1495: Ported value_tracker to OpenGL

  Added more documentation and inline operators to ValueTracker and ComplexValueTracker. Brought coverage for value_tracker.py to 100%. Removed ExponentialValueTracker.

• #1475: Add SVG elliptical arc support

Fixed bugs

• #1574: Fixed error when processing SVG with omitted elliptical arc command

• #1596: Fix indexing for non-whitespace tex arg separator
