Description: 1. Algorithm Overview
If using an event loop to control the angle β from 0 to 2π, then draw the flower is static. If the timer event so that β increases every time a certain value, and draw the corresponding line segment, then draw the flower is dynamic. If you add a timer event in the time factor, that equation becomes: x = Asin (nβ) cos (β+ t), y = Asin (nβ) sin (β+ t) changing the value of t, and Each t draw β from 0 to 2π corresponding to the graphics, then draw the flowers will spin. If the line drawn between the endpoints, then draw the flower is hollow if drawn from the center line to the end, the draw of the flower is solid.
