3D representation of call price calculated using Black-Scholz method. The three axis show the Stock price, Strike price and Volatility. Time to expiration and interest rate are fixed by a control panel and can also be modified to generate a different 3D volume. The horizontal plane represents a constant volatility surface. The colors represent the call values. The black lines show the contours of call prices in 5 dollar intervals on this horizontal plane. The near vertical surface represent a 3D isosurface of call price at 22.1765 picked by using a 3D cursor on the horizontal plane. The sphere represent a call price for a specific combination of Stock price, Strike price and Volatility.
