Dear student,

By just changing the i to -i in map function the processing application draws the shape in opposite direction so the output gets flipped

float angle=map(-i,0,numRows,0,TWO_PI);

As i dont have your complete code i cannot show you output.

If you have any doubt please comment below for clarification
