MathAnimation VS KeenWrite

https://github.com/ambrosiogabe/MathAnimation

If you’ve ever tried to make a mathematical animation (think 3Blue1Brown), it’s a real pain. I was using manim for awhile to make animations for my YT channel, but the whole iteration process felt very slow and repetitive. So I thought I would recreate manim over the weekend, except with a GUI and real-time feedback. It’s been a year and a half and I’m hoping this weekend will be done soon so I can move on and start making videos again.

So far, it does a lot, but it still needs a lot of polish and refinement. The readme gives some gifs and a better idea of the feature set right now.

Win32 definitely has some stinkers. But, video encoding APIs definitely take the cake for me. I've only tried a couple of FFmpeg's APIs and AV1's API, but my God, these are the worst API's I've ever had to deal with.

Just as an example, all I wanted was an API like this[0] for FFmpeg. In order to implement that API (which in my opinion is reasonable), I had to write this monstrosity[1]. It took me a solid week to find an example of how to do this, then another few days of fiddling until I finally just barely got something working. Then I threw in the towel even though the performance was horrible. I tried again a year later and spent another month wrestling with AV1 :/

The amount of leakage going on in these APIs is absolutely insane. I shouldn't have to know the intimate details of how video encoding works to use your library. If I do, then I may as well write my own encoder at that point.

I just so happen to be working on a real-time Gui first replacement for manim :)

It still has a ways to go, but I was able to create one video with it so far and I'm working on all the pain points I ran into while using it. Feel free to check it out if you're interested!

I'm using C++ for a minecraft clone that I've been tinkering on for the past year[0]. I also plan on using embedded lua for scripting, and I'm using RML UI for game HUDs, ImGui for development tools, and OpenGL for graphics. I use premake for my build system but plan on switching to CMake.

I'm also using it for an animation tool[1]. I've been using 3Blue1Brown's Manim (written in Python) which is amazing, but it lacks real-time editing and proper 3D blending. It also lacks audio synchronization, 3D texture support, and some more complex features that I'd like to add :)

KeenWrite is my free, open-source, cross-platform desktop Markdown editor that can produce beautifully typeset PDFs. I started working on it years ago to help write a novel that has a complex timeline and I couldn't find a text editor that would allow me to integrate a character sheet with the story itself.

Here's what I mean by using variables directly:

CommonMark doesn't propose a standard for bibliographic references. Would anyone find the editor more appealing if it had cross-references and citations?

My cross-platform desktop text editor, KeenWrite, allows users to define variables in an external YAML file. The editor calls out to Kroki[1] to convert text-based diagrams to SVG. The diagrams can reference variables and are rendered using EchoSVG[2].

KeenWrite[3] can produce PDF documentation from Markdown documents that has PlantUML diagrams with elements stored in an external, machine-readable file. Here are screenshots showing variables on the left, diagram text in the middle, and a real-time render on the right:

KeenWrite supports all diagrams offered by Kroki, which includes "diagram-plantuml".

Although not interactive, I've created a video series that shows advanced usage of Markdown. Namely R, external variables, diagrams, math, annotations, and a different approach to metadata:

Tutorial 4 shows basic Markdown:

The top-right of each video shows keyboard and mouse clicks to help follow along.[1] My desktop text editor, KeenWrite[2], is used in the tutorials.

My template script provides a way to make user-friendly shell scripts. In a script that uses the template, you define the dependencies and their sources:

I didn't create the fork, nor am I affiliated with the project. I use it in my text editor, KeenWrite to rasterize SVG.

KeenWrite Themes[1] are instructions that tell ConTeXt how to typeset XHTML documents (content) into PDF files (presentation). I made a tutorial that shows how my FOSS desktop text editor, KeenWrite[3], allows users to write in Markdown to typeset a document against a particular theme.

Before it can be used for scientific papers, it needs cross-references, which, unfortunately, aren't part of the CommonMark specification.

I posit that the vast majority of LaTeX users don't grok how to separate content from presentation. When I asked a question on TeX.SE about how to adjust the line spacing between enumerated items (spanning a couple dozen enumerated lists), the vast majority of people voted for the answer of using `\itemsep0em` to tweak each list ... individually.[4] The correct answer, IMO, is to fix the problem globally, and not waste time tweaking individual lists.
