Baseball field at my school?

In designing a baseball field, this visualization is intended to determine where a home run ball would land if it just clears an outfield barrier with given height and distance from home plate. This website indicates that approximately 30° is a reasonable "launch angle" for such a home run ball. Ignoring aerodynamic and environmental factors (air resistance, backspin, humidity, wind,...), the pertinent physical dimensions may be adjusted with the sliders.
