Math Anim

This is a tool I use to create animations for my videos on my YouTube channel. You can see an example of a video created using this tool here. My goal is to have nearly identical animations to those produced by Manim, except in realtime with a GUI+audio preview to enhance the editing process.

This is a small GIF showcasing some of the capabilities of this tool:

Supported Platforms

Windows

Compiling on Windows

Requirements

CMake 3.16 or later (download here)
YASM Assembler version 1.2.0 or later
- Download the yasm exe from the following link
- Rename yasm-*-win64.exe to yasm.exe
- Copy yasm.exe into a location that is in the PATH environment variable

First clone the repository and the submodules by running:

git clone --recurse-submodules -j8 https://github.com/ambrosiogabe/MathAnimation

NOTE: Depending on what version of Git you have installed, the command above may or may not initialize all the submodules correctly. If you run into errors when running CMake, make sure each submodule has been cloned properly, and if not try running git submodule update --init --recursive.

Compiling

NOTE: Make sure that you have installed the requirements listed above.

Run the following commands in the project root:

mkdir build 
pushd build 
cmake ..
popd

Then open the project build/MathAnimationsPrj.sln or compile it from the command line using the MSVC developer's prompt.

NOTE: If you want to build the project without launching Visual Studio run msbuild MathAnimationsPrj.sln in a command prompt for Visual Studio.

Gizmos are available in this view to drag objects around
You can click on objects here to pull up their properties in the inspector
Mouse scroll wheel to zoom
Click mouse scroll wheel to pan

Animation View:

Final rendered view of the current scene
Press play/stop to start the animation
- Press space at any time to play/stop the animation as well

Export Video:

Export the final animation as an mp4 file

Timeline (can be found in the Timeline tab):

- Red means it's on, white means it's off
Reset zoom by pressing the Undo-All button to the right of the zoom bar
Create new timeline tracks by right-clicking the left panel
Add/Remove audio waveform preview by right-clicking the left panel
Drag/drop animations onto the timeline
Drag cursor by clicking the ruler and dragging
Delete clips by selecting and pressing Delete on your keyboard
Resize clips by clicking edge of clips
Move clips by clicking and dragging the clips

Animations (can be found in the Animations tab):

Move To animation (moves an object to the specified position)
Create Animation (renders the outline of the object/children and then fills in the shapes)
Un-Create (Create in reverse)
Fade In
Fade Out
Replacement Transform (morphs one object/children into another object/children)
Rotate To (NOT IMPLEMENTED)
Animate Stroke Color (NOT IMPLEMENTED)
Animate Fill Color (NOT IMPLEMENTED)
Animate Stroke Width (NOT IMPLEMENTED)
Shift (BROKEN)
Circumscribe (plays an animation where a line surrounds the object/children then disappears)
Animate Scale

Scene Tab:

Object is green if it's animating, gray if it's inactive, and white if it's active
Right-Click to add animation object
Select object and press Delete on your keyboard to delete it
Rearrange the scene heirarchy by clicking and dragging the objects around

Animation Objects (can be found in the Scene tab):

Camera
Text Block (add text using any font installed on your machine)
LaTeX Object (add LaTeX as an object in the scene)
Square
Circle
Cube (STATUS UNKNOWN)
Axis (NOT IMPLEMENTED)
SVG File Object (import SVG files as objects in the scene)
Script Object (drag scripts created in the assets panel here to generate custom objects)
Code Block (like text block, except it highlights the code with the language/theme selected)
Arrow

Animation Object Inspector:

Click on any object in your scene tab to pull up its properties here
If there is a button with a Copy symbol to the right of it, clicking that will apply the change to all children
SVG scale determines the resolution to render to the SVG cache. Increasing this increases the fidelity, but you have limited space so don't increase it too much.

Animation Inspector:

Click on any segment in your Timeline to open its properties here
Anim Objects dropdown allows you to add animation objects to this animation. Just drag the animation object from your Scene panel into the drop area after pressing Add Anim Object
Change the animation curve or whether an animation is Synchronous or Lagged

App Metrics:

If you feel like the app is being slow, open this to get more detailed information such as FPS and the load on the app

Editor Settings:

Change the scene view from wireframe/filled
Adjust editor camera sensitivity
