Constants (might move from this module)

two_pi :: Radian

half_pi :: Radian

Generate points.

polygonPointsV :: Floating u => Int -> u -> Point2 u -> [Point2 u]

polygonPointsV : num_points * radius * center -> [point]

hpoints :: RealFrac u => u -> u -> (u, u) -> [Point2 u]

hpoints : ypos * step * (x0,x1) -> [point]

Generate points in a horizontal line between x0 and x1.

Note - the step increment is w.r.t. 0 rather than x0. x0 and x1 are just the range. An example:

 hpoints 0 10 (5,35)

 [P2 10 0, P2 20 0, P2 30 0]

vpoints :: RealFrac u => u -> u -> (u, u) -> [Point2 u]

vpoints : xpos * step * (y0,y1) -> [point]

Generate points in a vertical line between y0 and y1.

Note - the step increment is w.r.t. 0 rather than y0. y0 and y1 are just the range. An example:

 vpoints 5 100 (50,500)

 [P2 5 100, P2 5 200, P2 5 300, P2 5 400]
