A-shape: April 2013

A-shape

A-shape is an iPad and iPhone app. It can allow you to create interesting shapes, with affine transformation.

We do an iteration:


for i = 0 to Total Objects
  xs = X
  ys = Y

  x = xs * R * cos(teta) - ys * S * sin(psi) + E

  y = xs * R * sin(teta) - ys * S * cos(psi) + F

  Object's size = Total Objects - i

  Draw the object at coordinate (x,y)
  Rotate the object by Rotation Increment

end

Try different parameters, objects and colors, you may find the result interesting at the end of the iteration.

Here are a couple of examples
