<p><i>January the 16th, 2000</i>
|
|
|
|
<p>It looks like both X11 and Win32 version have reached a comparable usability stage.
|
|
They are still missing many GLUT API 3 features, but the number is getting smaller and
|
|
smaller every day :)
|
|
|
|
<br><ul><li><b><font size=+2>input devices</font></b></li>
|
|
|
|
<p>Keyboard and mouse seems to work well. There is a big guess about the mouse buttons
|
|
count under X11 (always 3) -- I must remember to correct the menu activation code if
|
|
this shows to be invalid.
|
|
|
|
<p>None of the bizarre input devices found in GLUT API is supported (and probably won't).
|
|
|
|
<p>Steve Baker contributed the joystick code. It should work fine, as it did in PLIB,
|
|
but I haven't tested it out yet. It might not compile under FreeBSD, as I had to
|
|
convert it from C++ to C and had no possibility to compile it under FreeBSD (the Win32
|
|
version had some typos, but I've already fixed them).
|
|
|
|
<br><br><li><b><font size=+2>pull-down menus</font></b></li>
|
|
|
|
<p>Pull down menus seem to work. The menu is displayed using OpenGL, so it requires
|
|
the window's contents to be refreshed at an interactive rate, which sometimes does not
|
|
happen. That's why I'll consider adding optional window-system menu navigation later.
|
|
For now -- extensive testing is what I believe should be done with the menu system.
|
|
|
|
<br><br><li><b><font size=+2>fonts</font></b></li>
|
|
|
|
<p>Bitmap fonts support is done. However it would be good to add two more API functions
|
|
-- glutBitmapString() and glutStrokeString(), which should limit the quantity of state
|
|
changes when drawing longer strings.
|
|
|
|
<p>Good that somebody finally told me where to get the stroke fonts data from... XFree86
|
|
sources contain the ROMAN and MONO ROMAN stroke fonts data. For now stroke fonts are
|
|
rendered using the bitmap font GLUT_BITMAP_8_BY_13.
|
|
|
|
<p>What has changed is the way the fonts are specified. I moved to the GLUT's strange
|
|
way of supplying (fake for freeglut) font data pointers instead of some nice enums.
|
|
Hope it helps in achieving the binary compatibility between freeglut and GLUT.
|
|
|
|
<p>Added two new API calls: glutBitmapHeight() and glutStrokeHeight(), that return
|
|
a font's height. Hope this doesn't break the GLUT compatibility a lot.
|
|
|
|
<br><br><li><b><font size=+2>mouse cursor</font></b></li>
|
|
|
|
<p>Need to have own cursor shapes, so that freeglut can pass them to the windowing
|
|
system, draw them using glBitmap() and/or texture mapping. The cursor shapes are very
|
|
probable to be found in XFree86 sources.
|
|
|
|
<br><br><li><b><font size=+2>indexed color mode</font></b></li>
|
|
|
|
<p>This might work, however I have not tested it yet. glutGetColor/glutSetColor is not
|
|
implemented. Again, looks like a single Xlib call, but there might be some problems
|
|
with the colormap access. Need to switch into indexed color mode some day and check it
|
|
out (does Mesa 3.1 work with indexed color mode?)
|
|
|
|
<br><br><li><b><font size=+2>planes</font></b></li>
|
|
|
|
<p>Overlays are not supported, but one of the GLUT conformance tests fails due to
|
|
glutLayerGet( GLUT_NORMAL_DAMAGED ) returning FALSE when the window has actually
|
|
been damaged.
|
|
|
|
<p>Layers would be good for drawing the menus and mouse cursor, as they wouldn't force
|
|
the application redraw to update their state.
|
|
|
|
<br><br><li><b><font size=+2>init display string</font></b></li>
|
|
|
|
<p>I am in middle of the fight with the init display string. It's parsing OK, now it
|
|
would be cool to make it impress some effects on the display...
|
|
|
|
<br><br><li><b><font size=+2>game mode</font></b></li>
|
|
|
|
<p>Is the game mode string parsed correctly?
|
|
|
|
<br><br><li><b><font size=+2>geometry</font></b></li>
|
|
|
|
<p>Andreas Umbach has contributed the cube and sphere code. The teapot rendering is
|
|
done using free SGI code. I have also added the cone rendering, however it is missing
|
|
normal vectors (just as Andrea's wireframed cube does). All of the glut*hedron()
|
|
functions await to be implemented.
|
|
|
|
<br><br><li><b><font size=+2>obvious bugs</font></b></li>
|
|
|
|
<br><br><ol>
|
|
<li>
|
|
the visibility/window status function is a conceptual mess. I had to peer into the GLUT
|
|
source code to see what actually happens inside. It helped me a bit, but still one of
|
|
the visibility tests fails. This is probably the reason for which a window covered by
|
|
enlightenment status bar is marked as hidden and does not get redrawn.</li>
|
|
|
|
<li>
|
|
GLX 1.3 spec states that glXChooseVisual() et consortes are deprecated. Should move to
|
|
glXFBConfig.</li>
|
|
|
|
<li>
|
|
need to investigate what happens when initial window position is set to (-1,-1). GLUT
|
|
specification says, that the window positioning should be left to the window system.
|
|
And I do not know how to force it do so...</li>
|
|
|
|
<li>
|
|
I was told it is wrong to have the redisplay forced in the main loop. Is that right?</li>
|
|
|
|
</ol><br><li><b><font size=+2>not so obvious bugs</font></b></li>
|
|
|
|
<br><br><ol>
|
|
<li>some of the tests freeze because they do not generate the glutPostRedisplay() call
|
|
every frame. Again, this is somehow handled by GLUT, but I can't see how. And why.
|
|
|
|
<p>Looks like I've fixed it (or rather hacked it?) by forcing a redisplay every
|
|
frame, but this is no good and kills interactiveness of my console :D</li>
