LME

Animation engine for Mathematical simulations in C++. This project is highly inspired from 3b1b's Manim. LME is built with C++17 on Visual Studio 2019 and Windows 10 platform. It can be used for making Math videos as the animation is converted to videos on the fly. It consists of wide range of animation classes that can be used for Mathematical Simualations.
NOTE: This project is highly under production.

Use Cases

• It can be used as Graphing Application to plot mathematical functions and parametric equations.
• For Data Visualization as it has all tools built in or can be extended.
• For Data Structure and Algorith visualizer.
• It can used as svg rendering engine.

Example

class TestScene : public laal::Scene
{
public:

	void Construct() override
	{
		laal::Line ln(Point(-1, 0, 0), Point(1, 0, 0));
		ln.StrokeColor(laal::ORANGE_RED);
		Add(&ln);

		auto func1 = [](double t)
		{
			return t;
		};
		auto func2 = [](double t)
		{
			return (1.0 / gmtl::Math::TWO_PI) * gmtl::Math::sin(t * gmtl::Math::TWO_PI);
		};

		laal::ParametricCurve pc(func1, func2, -1, 1);
		pc.StrokeColor(laal::BLUE_VIOLET);
		Add(&pc);

		laal::Arrow ar(Point(0, 0, 0), Point(0.5, 0.0, 0.0));
		Add(&ar);

		laal::ShapeGroup sg;
		laal::Dot dt;
		dt.Translate(0.5, 0.0,  0.0);
		sg.Add(&dt);
		laal::Line ln1(Point(0.0, 0.0, 0.0), Point(0.5, 0.0, 0.0));
		ln1.StrokeColor(laal::WHITE);
		sg.Add(&ln1);
		Add(&sg);

		laal::FollowPath fp(&sg, func1, func2, -1, 1, 3.0, 0);
		fp.EaseFunction(laal::EaseInOutExpo);
		Add(&fp);
		fp.Begin();
		Play();
		Wait(0.5);
	}
};
