    OpenGL
    § Write a short programming segment that draws the triangle fan shown
    below.
    You do not have to worry about setting projections, opening windows,
    setting the camera, transformations, …. Just the code to draw the triangle
    fan. Make sure triangles are in counterclockwise order
    (0,1)
    (-3,3)
    (-1,5)
    (1,4)
    (3,2)

    Mesh Data Structure
    § Store values in the mesh data structure to define a right-angled triangle at
    coordinates [0, 0, 0]. Legs are aligned to axis X and Y, respectively. Its length
    is 50.
