3D Grapher in QB64 using OpenGL

GitHub Logo

Descripton:

  • Plots real-valued surfaces defined as z=f(x,y) in 3D.
  • User specifies f(x,y) i.e. sin((x^2)-(y^2)), via input dialog or file.
  • Height map generated by Sxript evaluator.
  • Graphics generated using OpenGL commands.

Controls:

  • Left-click+drag mouse on screen to rotate view about z-axis.
  • Mousewheel adjusts zoom factor.
  • SPACE swaps between solid vs mesh rendering modes.
  • Right-click to enter new function f(x,y).
