July 2013 an announcement was posted that began:
Epspline (as in Edit-Povray-SPLINE) is a utility for POV-Ray users:
a simple 2D graphical editor of lathe and prism objects.
Download links, and a few samples, are available at:
November 2013 POV-Ray 3.7 was released. Some bugs in Epspline
were exposed, and have been fixed.
The new version of epspline is 0.0.4.3, available at the URL above.
The preview, with POV-Ray 3.7, would produce a message dialog
warning of an incorrect option. That is because epspline
was stripping options off the ".POV" type handler in a case
sensitive manner, but the case of the string added to the MSW
registry seems to have changed with the POV-Ray 3.7 installer.
Ultimately, the preview worked. Fixed.
The preview window might not appear at all with POV-Ray 3.7.
Epspline had included `-visual DirectColor' to the POV-Ray
command in response to unwanted transparency in the POV-Ray
window. There was an environment variable that would remove
`-visual DirectColor' from the command, but it was not
documented (it is "POVRAY_NO_DIRECTCOLOR"). With POV-Ray 3.7
using SDL, `-visual DirectColor' is not wanted and causes
POV-Ray to quit. This release of epspline will refrain from
adding that option, so POV-Ray 3.7 should work for the preview.
For those still using POV-Ray 3.6, and having unwanted
transparency in the display window, `-visual DirectColor' can
be added to the command in a new preferences dialog (under
edit menu). Or, for those so inclined, set the environment
variable "POVRAY_USE_DIRECTCOLOR" 'yes'||'true'||'on'.
The old wxWidgets 2.6 will no longer work. The new wxWidgets 3.0.0
(released around the same time as POV-Ray 3.7; ecce signum) has
nice improvements and should be preferred if possible, *but* the
GTK2 build of wxWidgets 3.0.0 works better than the GTK3 build,
at least on the systems the author has for testing. The GTK3
build *does* work with epspline, but with oddities on the author's
systems. It might be fine on other systems; feedback would be
appreciated (see COMMENTS below).
The URL given above points to a page that is in fact a blog page,
so there is a comment submission form. Comments are welcome (and
easy and fun and really in style!).
