14:23.32 siggraph hmm
14:23.47 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libtclcad/tkCanvBezier.c:
14:23.47 CIA-9 BRL-CAD: finally rewrite tkCanvBezier to NOT use libtk internal headers (as it was
14:23.47 CIA-9 BRL-CAD: written as a proper new libtk Canvas type, but hasn't been pushed through the
14:23.47 CIA-9 BRL-CAD: tcl/tk 'TIP' process). this change should make it feasible to compile this code
14:23.47 CIA-9 BRL-CAD: without having to have a copy of the Tk sources around .. more testing needed.
14:24.17 siggraph justin_: you got a brief mention at one of the courses yesterday from Ingo iirc
14:26.01 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libtclcad/tclcadTkSetup.c: remove old comment
14:26.59 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libtclcad/tkImgFmtPIX.c: removing the asize.c bn_common_* file autosizing functions, consolidating them to libfb. so update the function names to fb_ now
14:39.10 CIA-9 BRL-CAD: 03brlcad * 10brlcad/include/config_win.h: windows apparently doesn't have socklen_t defined, so make it an int so that WIN32 hacks can be removed
14:39.42 clock_ bor #ifndef socklen_t #define socklen_t int #endif
14:48.52 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libbu/parallel.c: run the provided function single-threaded even if bu_parallel() is called on a system that doesn't have PARALLEL support compiled in
15:01.47 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/rt/ext.h: don't need to (nor should we) declare worker() here
15:02.37 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/rt/worker.c: reorder functions so that forward declarations are not needed
15:03.53 CIA-9 BRL-CAD: 03brlcad * 10brlcad/ (32 files in 9 dirs):
15:03.53 CIA-9 BRL-CAD: refactor the three asize.c implementations (libbn, libfb, & canon) into just
15:03.53 CIA-9 BRL-CAD: one. libbn had the most comprehensive and updated version, but the logic
15:03.53 CIA-9 BRL-CAD: belongs in libfb. so, the bn_common autosizing functions are now consolidated
15:03.53 CIA-9 BRL-CAD: to libfb, refactoring accordingly.
15:20.55 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/fbserv/ (Makefile.am fbserv.c fbserv_win.c):
15:20.56 CIA-9 BRL-CAD: refactor fbserv.c and fbserv_win.c so that there is only one file that
15:20.56 CIA-9 BRL-CAD: supports/contains all of the mods that fbserv_win.c was presuming. this needs
15:20.56 CIA-9 BRL-CAD: testing but is more functionally clean, relying on configure-style tests/defines
15:20.56 CIA-9 BRL-CAD: instead of WIN32 where easily possible
15:33.23 CIA-9 BRL-CAD: 03brlcad * 10brlcad/configure.ac: (log message trimmed)
15:33.23 CIA-9 BRL-CAD: try enabling the automatic detection/compilation of tcl/tk now that
15:33.23 CIA-9 BRL-CAD: tkCanvasBezier is cleaned up to not use internal Tk headers. probably still
15:33.23 CIA-9 BRL-CAD: need to work on Tcl autopath issues, but give it a shot. also add a slew of
15:33.23 CIA-9 BRL-CAD: checks for WGL so that a new framebuffer and display manager interface may be
15:33.26 CIA-9 BRL-CAD: defined on Windows that is separate from the ogl interface. this is important
15:33.28 CIA-9 BRL-CAD: for cygwin/mingw systems where it is possible to use both wgl and ogl style
15:34.20 CIA-9 BRL-CAD: 03brlcad * 10brlcad/include/dm-wgl.h: initial dm-wgl.h header for a new 'wgl' interface, separating it from the X11-based ogl interface and cleaning up the code
15:35.11 CIA-9 BRL-CAD: 03brlcad * 10brlcad/include/dm-ogl.h: make the 'ogl' interface be X11 OpenGL only. windows is being moved to its own 'wgl' interface
15:38.05 CIA-9 BRL-CAD: 03brlcad * 10brlcad/ (NEWS include/light.h src/liboptical/sh_light.c): allow unlimited light samples during ray-tracing instead of a fixed compile-time count (was 128)
15:39.18 CIA-9 BRL-CAD: 03brlcad * 10brlcad/misc/win32-msvc7/fbserv/fbserv.vcproj: fbserv_win.c was consolidated into fbserv.c
15:40.14 ``Erik dagnabbit, another hchange to configure.ac
15:40.58 CIA-9 BRL-CAD: 03brlcad * 10brlcad/misc/win32-msvc7/libdm/libdm.vcproj:
15:40.58 CIA-9 BRL-CAD: use the new DM_WGL interface instead of the former DM_OGL interface so that the
15:40.58 CIA-9 BRL-CAD: latter may also be compiled at the same time (e.g. cygwin/mingw environments)
15:40.58 CIA-9 BRL-CAD: but also to allow the ogl interface to consistently imply just one interface.
15:41.12 *** join/#brlcad b0ef (n=b0ef@062016141085.customer.alfanett.no)
15:44.28 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libdm/dm-ogl.c: update comment to note that the ogl interface is specifically an X11 OpenGL interface (i.e. it's XGL.. might want to rename it to that someday, but oh well). ws
15:45.29 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libfb/Makefile.am: libfb now compiles asize.c as it was updated and refactored with the better libbn version. compress.c is not really relevant/useful any longer.
15:46.23 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/liboptical/sh_prj.c: unused/unnecessary ../rt/ext.h header
15:47.13 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/rt/ (Makefile.am light.h): the 'local' light.h header was redundant with include/light.h so remove it
15:50.10 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libsysv/ (9 files): remove the obsolete regular expression implementation, there is a src/other/libregex that is more up-to-date.
15:51.46 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libfb/compress.c: remove the obsolete compress.c file .. can be restored from revision history should someone really ever need to revisit compression on such old hardware
15:52.11 CIA-9 BRL-CAD: 03brlcad * 10brlcad/include/Makefile.am: install the new dm-wgl.h header
15:52.50 CIA-9 BRL-CAD: 03brlcad * 10brlcad/misc/win32-msvc7/ (libtclcad/libtclcad.vcproj mged/mged.vcproj): use the DM_WGL interface instead of DM_OGL
15:53.05 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/adrt/libcommon/Makefile.am: removed comment
15:53.52 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libbn/Makefile.am: remove asize.c file -- was refactored into src/libfb/asize.c
15:54.57 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libdm/Makefile.am: add dm-wgl.c to the compilation list based on the WITH_WGL automake symbol being defined by configure -- this allows the wgl interface to be simultaneously compiled alongside the ogl interface
15:55.52 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/rttherm/viewtherm.c: use the main light.h header, not the (now gone) private src/rt/light.h header
15:59.18 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libdm/dm-wgl.c:
15:59.18 CIA-9 BRL-CAD: add an initial implementation of a WindowsGL 'wgl' libdm interface using the
15:59.18 CIA-9 BRL-CAD: former dm-ogl_win32.c code as a basis. remove the XGL sections and add
15:59.18 CIA-9 BRL-CAD: boilerplate checks that makes sure this interface can be compiled alongside the
15:59.18 CIA-9 BRL-CAD: 'ogl' interface. expects DM_OGL to be defined in order to get functionality.
16:01.31 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libfb/if_wgl.c:
16:01.32 CIA-9 BRL-CAD: initial stub of a libfb IF_WGL 'wgl' interface to replace usage of 'ogl' on
16:01.32 CIA-9 BRL-CAD: Windows. this is done to support the libdm design intent of interfaces for each
16:01.32 CIA-9 BRL-CAD: style of display manager, instead of piggy-backing on top of 'ogl' and
16:01.32 CIA-9 BRL-CAD: complicating the code with preprocessor WIN32 checks everywhere. haven't
16:01.32 CIA-9 BRL-CAD: updated the names/code yet.. just a stub file.
16:02.13 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libfb/Makefile.am: add the new if_wgl.c file, not yet compiled
16:03.39 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/ (20 files in 20 dirs): update the usage of LIBRT from configure to be RT instead so that it is consistent with the other BU, BN, WDB etc library defines, using the LIB prefix mostly on third party or external libraries instead.
16:09.01 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libfb/Makefile.am: check for the WITH_WGL symbol from configure to add the WGL cflags
16:09.37 CIA-9 BRL-CAD: 03brlcad * 10brlcad/configure.ac: oops, typo.. close the macro
16:11.47 CIA-9 BRL-CAD: 03brlcad * 10brlcad/configure.ac: bah, another.. wgl_link_works, not gl_link_works
16:21.24 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libfb/if_wgl.c: update names, s/ogl/wgl/
16:22.01 CIA-9 BRL-CAD: 03brlcad * 10brlcad/src/libfb/Makefile.am: compile if_wgl.c now that it'll check for IF_WGL being defined
16:25.26 ValarQ siggraph: changed nick?

18:01.56 siggraph and more importantly, is this the latest cvs or some source release?
18:02.13 IriX64 something ive worked on.
18:02.35 IriX64 from the source tarball 7.6.0 and up to 7.8.2 from sourceforge.
18:03.04 IriX64 cant be a backtrace think why.
18:03.30 ValarQ IriX64: "The cannon, in the form of the tank gun, has made the transition from smoothbore to rifled, and is moving back to smoothbore."

18:03.43 IriX64 dont have a t90 debugger man, sorry :)
18:04.07 IriX64 really valarq?
18:04.17 IriX64 ill look that up right now.
18:07.39 ValarQ IriX64: yeah, it seems as they use longer projectiles there is no need for rifled cannons
18:08.06 IriX64 they cheat they use fins :)
18:09.11 IriX64 like arrows, tell them to use the fins to impart a stability spin and minimize tumbling.
18:10.20 IriX64 btw that v10.0.0 is simply what I call mine :)
