It’s time to add curves to the graphics engine. Everything will work as before, we will have three more shapes to draw.

Add the following commands to the parser

• circle: adds a circle to the edge matrix - takes 4 parameters: cx, cy, cz, r
• hermite: adds a hermite curve to the edge matrix - takes 8 parameters: x0, y0, x1, y1, rx0, ry0, rx1, ry1
  • The curve is between points (x0, y0) and (x1, y1).
  • rx0, ry0 and rx1, ry1 are the rates of change at each endpoint
• bezier: adds a bezier curve to the edge matrix - takes 8 parameters: x0, y0, x1, y1, x2, y2, x3, y3
  • This curve is drawn between (x0, y0) and (x3, y3).
  • (x1, y1) and (x2, y2) are the influence points for the curve.

For help creating your own image, you might want to use the following graphs:
