<p><i>January the 2nd, 2000</i>
|
|
|
|
|
|
|
|
|
|
<p>The alpha version has been released yesterday. Today I have been busy with moving
|
|
|
|
|
the project site to the <a href="http://www.sourceforge.net">SourceForge</a>. As for
|
|
|
|
|
now there will be the web site available and I will give it a try to set up the
|
|
|
|
|
freeglut mailing lists. There will be no CVS access available for now (my dialup
|
|
|
|
|
internet connection sucks so badly that I wouldn't be able to work on the project).
|
|
|
|
|
After I am done with that, I will try announcing the project on www.opengl.org.
|
|
|
|
|
|
|
|
|
|
<p>Of other things, there has been rumours floating round the routers and hubs about
|
|
|
|
|
Mark Kilgard changing the GLUT's license, but this is unconfirmed. It would be really
|
|
|
|
|
cool if he did so, there's no better motivation to work than a bit of sound competition.
|
|
|
|
|
As for me, I already put too much work into the freeglut project to terminate it just
|
|
|
|
|
now. We'll see what happens next.

|
<p>Ho-ho-ho. Freeglut-1.3 works fine with `Tux the Penguin and the Quest for Herring'.
|
|
|
|
|
At least that's what Steve Baker, the author, says. Not only that, Steve has provided
|
|
|
|
|
us with the joystick code (from his great PLIB project) and numerous hints and tips
|
|
|
|
|
about making freeglut more useful (I will try to put the results of our discussion
|
|
|
|
|
on the <a href="structure.html">structure page</a>).
|
|
|
|
|
|
|
|
|
|
<p>As for other issues -- I promise I will start the Win32 port this weekend.
|
|
|
|
|
BTW. -- is there a decent cross compiler for Linux that generates Win32 executables,
|
|
|
|
|
so that I don't have to use windows for development? And what about Wine OpenGL
|
|
|
|
|
support?
|
|
|
|
|
|
|
|
|
|
<p>The package is now some 40kB smaller than the previous one. Did some general
|
|
|
|
|
clean ups, removed unnecessary configure scripts in the genfonts directory,
|
|
|
|
|
the configure cahce, the Makefiles and so on. Also, I have started introducing
|
|
|
|
|
the new internal structure, as described <a href="structure.html">here</a>.
|
|
|
|
|

|
|
|
|
<p><i>January the 6th, 2000</i>
|
|
|
|
|
|
|
|
|
|
<p>The missing glutInit() issue seems to be solved. Chris Purnell (fxGLUT author) says
|
|
|
|
|
that the GLUT window and menu creation functions call glutInit() if the caller didn't
|
|
|
|
|
do that before.
|
|
|
|
|
|
|
|
|
|
<p>The enumerations for GLUT_KEY_UP and GLUT_KEY_RIGHT were accidentally swapped.
|
|
|
|
|
They should be OK now. Hope the rest is OK :)
|
|
|
|
|
|
|
|
|
|
<p>Added two new API calls to freeglut-1.3 -- glutBitmapHeight() and glutStrokeHeight(),
|
|
|
|
|
as suggested by Steve Baker. This won't break the GLUT compatibility a lot, and I've
|
|
|
|
|
heard it can be useful. Here you go.
|
|
|
|
|
|
|
|
|
|
<p>The <a href="structure.html">structure</a> plans page has been updated. The numerous
|
|
|
|
|
feature hints from opengl-gamedev-l readers have been added.
|
|
|
|
|
|
|
|
|
|
<p>Somebody (Chris?) hinted me that the stroke fonts can be found in the XFree86
|
|
|
|
|
sources. I browsed through it and -- presto. Now I only need to define the stroke fonts
|
2014-12-05 01:00:27 +02:00
|
|
|
structure (should be very similar to bitmapped one) and write quite a simple parser.
|
2001-07-27 10:22:53 +03:00
|
|
|
|
|
|
|
|
<p>I've spent the (late) evening doing the init display string parsing and making
|
|
|
|
|
my logics classes homework :) Both is harder than I primarily thought, but fortunately
|
|
|
|
|
for me I can commit errors in one of those tasks. Guess which one? Argh. :)
|
|
|
|
|
|
|
|
|
|
<p><i>January the 8th, 2000</i>
|
|
|
|
|
|
|
|
|
|
<p>First of all, both the missing glutInit() and glutGet(GLUT_WINDOW_[X|Y]) issues are
|
|
|
|
|
fixed now. The first problem was solved thanks to Chris Purnell, who showed me the way
|
|
|
|
|
GLUT dealt with the problem. Good for me there's someone who reads it's source code (I
|
|
|
|
|
just felt it would be unfair for me to do so :D). The second problem was solved by
|
|
|
|
|
adding a XMoveWindow call just after the window creation and initial mapping. This is
|
|
|
|
|
strange. Maybe one of the Xlib calls between the creation and mapping spoiled the
|
|
|
|
|
window's coordinates?
|
|
|
|
|
|
|
|
|
|
<p>This makes even more GLUT tests work fine. The tests can be found in any decent
|
|
|
|
|
GLUT 3.7 distribution. Following tests produce a FAIL message: test18.c (some layer
|
|
|
|
|
issues), test19.c (see the GLUT_NORMAL_DAMAGED issue on the progress page), test22.c
|
|
|
|
|
(window stacking/visibilty problems), test23.c (glutInitDisplayString() is unfinished),
|
|
|
|
|
test25.c (the freeglut fonts differ a bit from GLUT's), test28.c (-iconic handling
|
|
|
|
|
is missing(?)). Gee :)
|
|
|
|
|
|
|
|
|
|
<p>I've spent another hour doing the glutInitDisplayString(), but it still is far from
|
|
|
|
|
being complete. And I've also started gathering information on doing the game mode
|
|
|
|
|
stuff. The video mode enumeration in both cases will be painful.
|
|
|
|
|
|
|
|
|
|
<p>There is a big issue with the window contents redrawing. Right now, it is forced
|
|
|
|
|
every time there are no events pending in the main loop. I know it's wrong, but it
|
|
|
|
|
without such an approach some of the test programs freeze soon after starting. Could
|
|
|
|
|
someone peer-review the main loop code please?
|
|
|
|
|
|
|
|
|
|
<p>I have decided to start the Win32 port this weekend. As for now, the code compiles
|
|
|
|
|
under vc++5.0. I will start making it work as soon as I download the pthreads library
|
|
|
|
|
and the newest version of GLib for Windows. It was quite a good idea to start the port,
|
|
|
|
|
as the Microsoft's compiler generates much more warnings and I had quite a few things
|
|
|
|
|
fixed for free.
|
|
|
|

|
|
|
|
<p><i>January the 9th, 2000</i>
|
|
|
|
|
|
|
|
|
|
<p>Doing the Win32 port all the day... Actually, there is enough code to make it work,
|
|
|
|
|
however I am sure only of that it compiles (more or less). I need to download the
|
|
|
|
|
pthreads-win32 library to get the GLib working first, and somehow I was unable to
|
|
|
|
|
do it during the weekend. Once again -- the Win32 port does not work yet. Oh, and
|
|
|
|
|
I need adding the __declspec(dllexport) thing...
|
|
|
|
|
|
|
|
|
|
<p>After it starts working, I'll have to clean up the code a bit, I guess...
|
|
|
|
|
|
|
|
|
|
<p><i>January the 10th, 2000</i>
|
|
|
|
|
|
|
|
|
|
<p>Here I am at three o'clock am, half-awake, uploading and downloading things for
|
|
|
|
|
freeglut. I never thought I'd be able to force myself getting up that early :)
|
|
|
|
|
|
|
|
|
|
<p><i>January the 16th, 2000</i>
|
|
|
|
|
|
|
|
|
|
<p>Both the flu and a terrible feeling about the dialup bills made me slow down
|
|
|
|
|
a bit, the internet activity I mean :). But here I am again uploading the latest
|
|
|
|
|
snapshot. The biggest news about it is the Win32 port working, with nearly all
|
|
|
|
|
features you can find in the X11 version implemented (still, it needs some debugging).
|
|
|
|
|
For the Unix port, game mode support (loosely based on SDL source code posted at Neal
|
|
|
|
|
Tringham's www.pseudonymz.demon.co.uk) and numerous bug fixes have been introduced.
|
|
|
|
|
|
|
|
|
|
<p>In order to compile the Win32 version, you'll need pthreads-win32 library (see
|
|
|
|
|
sourceware.cygnus.org), the GLib-1.2.x (www.gtk.org, I've been using the 1.2.6),
|
|
|
|
|
a working native compiler (Microsoft VisualC++ 5.0 in my case), and a bit of patience.
|
|
|
|
|
See the project files I've supplied for some definitions needed (FREEGLUT_LIBRARY_BUILD
|
|
|
|
|
needs to be declared when building the DLL), and don't forget freeglut joystick code
|
|
|
|
|
is making use of Win32 multimedia extensions (link against winmm.lib).
|
|
|
|
|
|
|
|
|
|
<p>Be prepared to meet the fact Mesa 3.1 (or at least my compilation) doesn't work very
|
|
|
|
|
well with this snapshot -- something's messed up when changing WGL contexts. This is
|
|
|
|
|
really strange, as the Microsoft's OpenGL works pretty fine, as does Dominik Behr's
|
|
|
|
|
miniGL thing. The assumption is that I've taken some approach that somehow is valid
|
|
|
|
|
with Microsoft's drivers, but is not OpenGL conformant. Could anyone check this out
|
|
|
|
|
please?
|
|
|
|
|
|
|
|
|
|
<p>My plan for next week is to add some lesser features missing, and start learning
|
|
|
|
|
maths as the session at my university is coming in really fast :) This way or another,
|
|
|
|
|
expect the next release not any sooner than next weekend (given that no nasty bugs get
|
|
|
|
|
digged out).
|
|
|
|
|
|
|
|
|
|
<p>Argh. Don't be surprised if the code doesn't compile under X-11 other than XFree86.
|
|
|
|
|
It could fail when trying to include the X11/extensions/xf86vmode.h include header,
|
|
|
|
|
in that case just comment out that inclusion line (found in freeglut_internal.h).
|
|
|
|
|
Is there any intelligent way to detect the existence of an include header, and if
|
|
|
|
|
it's autoconf to be the answer, how to use it?
