Math

Math Library (MathLib)

Graphite includes a built-in math library for 2D/3D visualization and scripting. It provides essential types and functions for geometry, plotting, and mathematical operations.

Main Classes

Point

Point class is used inside script for drawing single point. It is than added to plot.

namespace Graphite::Math {
	class Point {
		Point(std::array<float, 2> pos, std::array<float, 3> color);
		std::array<float, 2> getPos();
		void setPos(std::array<float, 2> pos);
		std::array<float, 3> getColor();
		void setColor(std::array<float, 3> color);
	};
};

Main Features

• 2D/3D point representation.
• Color management for points.

Plot2D

Plot is our 2D canvas where we draw elements. We add others Math classes to cells.

namespace Graphite::Math{
class Plot2D{
public:
  std::unordered_map<std::string, Graphite::Math::Point> point_cell;

private:
  void drawPoint(Graphite::Math::Point point);

public:
  Plot2D();
  ~Plot2D();

  void draw();

};
};

Main Features

• Creating plot and adding points.

};

};

Extending MathLib

You can add your own math types and functions by creating packages (in future) or extending the library in your scripts. Also you can add any header files to scripts.
