DiffGeomTool Version History

Version 1.1

  1. Changed layout.
  2. Added slider to adjust transparency of wireframe.
  3. Changed coloring scheme of surface.
  4. Changed color of vectors.
  5. Added pre-set function menu.
  6. Changed calculation of tangent plane. This fixed bug where tangent plane was sometimes not a square.
  7. Implemented OrderedGroups to force rendering of objects in a specific order.
  8. Fixed problem where objects would disappear when clicking "Graph" several times.
  9. I made tangent plane transparent.
  10. I changed how transparent objects are blended.

Version 1.0

  1. Changed default transparency to 0.5
  2. Fixed problem when input error in function fields casued applet to freeze.
  3. Changed coloring scheme of surface.
  4. Made fixed u and v curves thicker.
  5. Fixed u/v boxes are now unchecked as default.

Version 0.6

  1. Updated to use jnlp file to install java3d libraries consistent with latest version of java.

Version 0.5

  1. Changed "log(z)" to mean "log base e". This is reflected in the function choice menu.
  2. Bug fix: when selecting curves box, other associated boxes did become visible properly.
  3. Added slider to control transparency. Default is no transarency.
  4. Added wireframe box to turn wireframe on/off.
  5. Added light/shading to surface.
  6. Added automatic zooming in/out when surface is graphed.
  7. Added error check for base point of tangent plane and tangent/normal vectors to ensure base point is in domain.
  8. Tracking fixed u/v curves now takes into account radius_min in circular domain.
  9. Fixed bug that prevented click on tangent vectors box from selecting this box.
  10. Rearranged order of check boxes
  11. Tabbing between x,y, and z input fields goes to default caret position (left hand side of the box unless something has been entered).
  12. Fixed labels that were chopped off on Windows OS.

Version 0.4

  1. Fixed bug that occured when changing number of theta/radius points using circular grid.

Version 0.3

  1. Added ability to track fixed u/v curves using slider.

Version 0.2

  1. Fixed problem with fixed u/v curves leaving the surface for circular grid.
  2. Circular grid panel is moved to correct place.

Version 0.1

  1. Basic functionality-- graph parametric surface, tangent plane, tangent and normal vectors, and curves from fixing u and v.
  2. Either rectangular or circular grid can be used.
