Vector Functions with OpenGL/C++

This project can be use as C++ library or as graphic interface, in this moment, we just use as library.

Examples

F(x,y)=(-y,x)

F(x,y)=(cos[-y],sin[x])

F(x,y)=(-x,cos[y])

Compile

OpenGL and Glut

You must have OpenGL and Freeglut in your pc

Make

Follow the next instructions

make build
make

the executable file is in build/Examples.

Call in C++

void display(){
  glClear(GL_COLOR_BUFFER_BIT);
  glColor3f(0.0f, 0.0f, 0.0f);
  Field Func("+y^2","-x");            //Call the function
  Func.SetXYMaxMin(10, 10, 0.05f);    //Range of x and y, and vector size
  Func.SetXYVectorsQuanty(0.5, 0.2);  //Number of vector into the x and y range

  glutSwapBuffers();
}

List of posible equations

• f(x,y) = (x,y) write "x" or "y"
• f(x,y) = (x²,y²) write "x^2", "x*x" or "y^2", "y*y"
• f(x,y) = (x³,y³) write "x^3", "x*x*x" or "y^3", "y*y*y"
• f(x,y) = (x⁴,y⁴) write "x^4", "x*x*x*x" or "y^4", "y*y*y*y"
