Methods Summary

private void

calculateGridSizes(float numbersRadius, float xCenter, float yCenter, float textSize, float[] textGridHeights, float[] textGridWidths) Using the trigonometric Unit Circle, calculate the positions that the text will need to be drawn at based on the specified circle radius. Place the values in the textGridHeights and textGridWidths parameters. /* * The numbers need to be drawn in a 7x7 grid, representing the points on the Unit Circle. */ float offset1 = numbersRadius; // cos(30) = a / r => r * cos(30) = a => r * â
