Right. Yes, I'm still here,
and am pleased to announce the first new app in 10 years or so -
OneStoneĀ® SurfViewer. The premier feature is the creation of high-quality 3D surfaces defined by
any expression the user enters. This isn't restricted to a set of pre-defined expressions - with
very few exceptions, function of X, Y, r and/or Theta will be presented with OpenGLĀ® graphics - the
same 3D technology underlying major game engines. Where appropriate (single variable functions
of X or Y), 2D graphs are presented simultaneously. For more information, see the
OneStoneĀ® SurfViewer page. An upgraded version
scheduled for release in early 2026 will debut support for graphical analysis of solutions to linear and
non-linear differential equation problems. This upgrade will be free to current license holders when
released.

I'll also be publishing a series of code libraries in the near future. The first two are
add-ons for the WTL application framework,
a light-weight alternative to the more ubiquitous MFC framework. While WTL requires a higher
degree of familiarity with the raw Windows messaging model, it generally produces higher
performance, smaller apps than those produced with MFC. See the
Code Libraries page for more information.
