The CVE Big Board (to-do list)

Jobs are numbered chronologically, which may not be an ideal organization.

#	Job	Status
3	Avatars' heads should show who is talking	in avatar class but not called, use for VOIP status, prototyped by Ziad
9	Turn rooms' data from previous CS 579 courses into .dat format	2nd 579 CVE course data mostly done already
11	Get ssh tunnel mechanism working	launching tunnel from inside unicron doesn't work yet
13	dynamic state and server forwarding for whiteboards/blackboards	Use SVG subset? Develop/adopt generic dynamic state update protocol
14	add white/blackboard drawing to client	a "whiteboard session" tab
20	client needs automatic reconnect to server when connection drops	In recent, client was not hung after connection dropped.
25	refine local (photo-based) textures	replace GIFs with JPG's, but not until G5 is solved
26	try out UDP for avatar motion
26	add interesting virtual objects	followup Shyam's graphical implementation with dynamic behavior
28	add avatar orientation to persistent server state	angle is saved but not yet getting restored
30	add user statistics to persistent server state	so we can remember what users have done what for how long
43	server log forwarding	(limited) ability for admin users to request that logs be copied to them
45	client and server hang after guest login
48	add a way for end users to change their password
50	session recorder so clients can remember their own sessions	remember conversations and instructions delivered via chat; chat recorded to Moodle has been prototyped

63	re-enable mode 1 out of body movement	command line option or internal command
66	fix walls so they aren't infinitely thin	add thickness in a subclass
70	integrate Samat's mapview	turn it into a "widget" in place of static 2D map
71	add windows to more rooms that have them
72	control keys in chat widgets should route to 3D window commands
75	avatar's heads should rotate to match how much "up" or "down" they are looking	optional extra parameter of a \move command?
76	NMSU classroom wing decorations should be raised 1 meter
78	add version # check to protocol login	added to server; not checked by client yet
79	avatar jump command	look in Shyam/Anil CVE class project?
81	avatar (conservative) collision detection
83	watchdog needs to survive broken pipe errors
88	\who should tell where each person is and what they are doing	with some privacy options
89	moving backwards needs to be smoother, like forwards
91	doors should be able to stop in between open and closed	this used to work fine
96	switch to JPEG faces (and other textures?)	> 256 colors makes a big difference on faces; can't do until G5
98	Suck in "live" whiteboard content from hi-res webcam
100	save a snapshot of the whiteboard prior to each Erase op
101	define low-bandwidth graphics language	SVG replacement?
102	add faint lines at corners so they're more visible
104	graphical model.dat editor	or "live" in-CVE world editing
105	render (more) as needed when a door opens

110	add away-from-keyboard accounting in server
111	server does not always recognize logouts

117	fix spelling of "corridor"
118	autocreate missing avatars from guest.avt/guest.gif
120	implement a voice tunnel	tunnel our voice UDP via Unicron TCP? or other workaround for clients without valid IP #'s.

123	create an autorun.inf file to launch our installer from the CD	see microsoft's references
124	add -no3D option	CVE should be able to run on 2D-only clients
125	avatar eye height should be computed from avatar height	not hardwired to 1.5m
126	fix third person view "y" bug
127	IDE mouse click should set focus and does not	workaround is to press an arrow key

130	coordinate warps view out and away from building for no reason
132	upgrade teleport	support teleporting to rooms or users
133	doors' dynamic state should include locked/unlocked
134	add virtual keys
135	room-based autosharing of documents	IDE autoinvite/autoaccept
136	add command for server-download of whole virtual world
137	add commands for virtual world edits	\addroom etc
138	user.state files' x coordinate should be trimmed when written

147	screen goes white when new user logs in or logs out
148	avatars and ramps need to use WSection()	(check for any others?)
149	add \collect and \memory commands	improve remote info and administration
150	amaker dies when server is down	needs to check server is up before it even runs, and handle crashes without losing user avatar data.
151	NMSU's foyer/atrium needs improving

Server can die reporting a failed attempt to read a file not open for reading, reporting a read(file(:4500)), as if its possible for a listener to get promoted to regular mode when select() returned it, but it wasn't actually opened yet? Or maybe the file gets closed after select() has returned it. If an open network connection gets closed at the other end, maybe it should cause read()/sysread() to fail, instead of runerr?

Unicon Language / OpenGL / 3D Facilities To Do List

#	Job	Person	Status
U1	Font support	Omar	done; alpha testing
U2	Improve transparency support
U5	JPG texture support		needs retesting, known bug on Windows
U6	Fix FillPolygon to handle concave polygons		See GLU tesselation
U7	detect when we run out of texture memory
U8	add automatic mipmapping		on big video cards, anyhow
U10	detect graphics hardware specifications		can tell video ram on most machines
U11	debug or rewrite calls to gluScaleImage()		isn't this too slow?
U12	WriteImage() should support subwindows and/or 3D windows		code can be borrowed from where Texture() turns a 3D window into a texture
U13	add ability to free textures when no longer used		see glDeleteTextures(); maybe done, at least textures can be replaced
U15	create a more direct writeable texture type		opengl-native in-client-memory representation
U16	add (read-only) 3D platform attributes		glGetString() can return us glversion, glvendor, glrenderer, glextensions
U17	texturing in bad format should fail, not runtime error		and if a .JPG is in a file named .GIF, we should just succeed as JPG
U18	3D object selection support
U19	Unicon language should auto-catch broken pipe errors		and turn them into eof / failure
U20	add open(...,"m", timeout)
