- General problems:
-
- o It would be nice to have an option -idletime time. Where xlock would
- run after a certain idle time. (Here xautolock may help you, see
- above).
-
- o xscreensaver compatibility
- 2 of the writeable modes: mandelbrot, tube-> get them to RUN (compile ok)
- XPM capability needs to be improved.
-
- o -wireframe should be a mode option (i.e. you should be able to turn it
- on and off for a particular mode). Also a linewidth mode option would be
- nice
-
- o I got an error with moebius running it on opengl on a 24 bit TrueColor like:
- xlock -mode moebius -visual PseudoColor
- (all the gl modes are messed up anyway... all mono)
-
- o some configurations of linux: swarm has noise when bees go beyond screen
-
- o A few unintialized memory reads and memory leaks were detected in some
- of the code. grep for "PURIFY" in the source files to see where the
- remaining problems are. Also see docs/Purify for more details.
-
- o -mono does not work for XPM, especially cartoon (others use XBM when
- mono), also cage and stairs.
-
- o Options within a mode can not be duplicated in other modes. Temporary
- solution is to have xlock modes like "-neighbor" that only a few of the
- modes use.
-
- o -use3d -install is messed up on Sun's PseudoColor. Magenta boxes are
- seen on the star mode. In worm mode, worms might be red and magenta
- instead of red blue (and depending on SunCC or SunOS).
-
- o Not all resources are listed in "xlock -resources", e.g. nolock.
- If xlock is renamed these resources are not picked up.
-
- o Without any programs stealing your colors, like netscape
- xlock -modelist all -sequential -install -verbose
- Hit the middle button a hundred times (not to bad on an ultra actually)
- or try -duration 1 and let it sit for a while.
- The second time it runs the GL modes they have all lost some colors.
- This was only noticed on Solaris with pseudocolor. Also noticed on an
- ancient HP9000/380 HPUX9.0 with 6 bit depth (without netscape).
-
- o On a German keyboard and Linux if the password contains special
- characters (`|' vertical bar, `@' at-sign) while in debug mode
- everything works fine. This probably has something to do with the
- X11-keymapping, as these characters are composed with the right Alt-key
- on a German keyboard.
-
- o neighbors option for wator and voters... sometimes circles are not
- drawn in the correct spot. A -/+ wrap option would be nice also.
-
- o OpenGL and DT may be incompatible on PseudoColor. (MesaGL should be
- OK.) OpenGL frequently causes xlock to error out on non-default visuals.
-
- o -visual DirectColor if used with any of the with the writeable modes
- (mandelbrot, swirl, or tube) may corrupt the dynamic allocation of memory.
-
- o Errors in modes, if any, should not break lock.
-
- o Compile-time option to allow running of separate processes.
-
- o Fallback font if screen is small for marquee and nose... like bomb
-
- o make -n install prefix=/foo/bar does not work.
-
- o "xlock -mode random -modelist image -bitmap ./bitmaps/"
- It should change images when middle mouse is pushed or when
- -duration time runs out.
-
- o some sort of completion is used which may be confusing on UNIX
- Say if a ../bitmaps directory exists and ../bitmap does not
- xlock -mode random -modelist image -bitmap ../bitmap
- will try to load ../bitmaps as a file...
-
- o kill -HUP to change modes as well as middle mouse button. Needed when
- using -inroot .
-
- o jpeg/gif/animated gif support Fix ras for > 8 bit TrueColor
-
- o "-visual" commandline argument should accept "best" as well as
- PseudoColor, TrueColor, default, etc.
-
- o modes from xscreensaver :) : bubbles, moire, LMorph, halo, ImsMap, BlitSpin
-
-
- Mode specific problems:
- ----------------------
- Various modes need better refresh capability.
- Various modes need more mouse capability like pacman and worm.
-
- ant: round ants. This would involve masking and images to do efficiently.:q
-
- ball: can it be updated to use a pixmap instead of a slow circle fill?
-
- braid: should be made so that it can be interrupted quicker.
-
- bouboule: always starts at the bottom right
-
- bounce:
- sometimes a ball does not roll off another ball.
- momentum seems to be created.
- A -wall option, multiscreens should have balls bouncing between
- screens.
- -mode bounce -inroot may give BadWindow in X_GetWindowAttributes
- if run for a while, but the screen is not locked :)
- allow a background picture to be seen behind the bouncing football
- (soccer ball) in "bounce" mode. Thus a picture of your favorite
- team, etc. can be seen behind the bouncing balls.
- football version of "bounce" using a pigskin instead of a soccer ball for
- Americans/Canadians/etc.
- Different balls with different mass and size.
-
- bug:
- -neighbors option
- init_bug should be broken up so it can be interrupted
-
- dclock: needs a -led [LED] option
-
- ico:
- should have all the features of the original.
- triangular face objects do not look good when rotated.
-
- image: middle button should do something when called like
- "-bitmap ./bitmap/"
-
- flag:
- sometimes a refresh causes a white background rectangle
-
- hop: center and size many of the hops.
-
- kaleid: needs to be triangular.
-
- life:
- -find option to find new lifeforms. (mail the results out :) ).
- Allow more symmetric type rules as proposed by Dr. Andreen.
- When the bitmap is big it is rejected. Probably could be handled
- better but if accepted then the screen could be blank because there
- are bitmaps that are off screen.
-
- life3d: draws invisible cubes when it does not have to. The original
- MS DOS code weeded this out, but it did not seem to port to X.
- Also see life.
-
- marquee:
- "-messagefile filename" truncates a large file.
- "-message string" does not handle Control-H correctly.
-
- mountain: -size # for mountain should do something.
-
- nose: should handle Control-H better for underlining and accents.
-
- pyro: needs XDrawSegments code similar to swarm to give it depth.
-
- slip:
- should be less jarring
- get rid of single color blotch.
- should be made so that it can be interrupted quicker.
-
- star:
- fractal cracks when hit by rocks (with sound?)
- user defined ships (user defined pixmaps like eyes and pacman).
- stars should look more star-like "*"'s
-
- wire: it needs a better circuit generator.
-
- xglock: Needs a lot of work.
-
- kscreensaver: port xlock to KDE.
-
-
- New mode ideas... (some may be very hard :) ):
- ---------------------------------------------
- o "dead" a Grateful Dead mode with dancing bears/skeletons/turtles.
- (Or maybe "nose" in a tie die?)
- o "floyd" a Pink Floyd mode from the cover of "Dark Side of the Moon"
- with a turning prism and rainbow effect.
- o "graph" a random planar graph drawn ... filled in by a 5 (or 4 :) )
- coloring algorithm.
- o "invert" a demonstration of turning a sphere inside out without creating
- any kinks (two surfaces can occupy the same space at the same time).
- Randomize the viewing angle.
- o "minimal" a random minimal surface generator.
- o "snow" mode with a nice Winter scene picture background and snowflakes
- falling
- o "squig" mode from squig/xsquig (xsquig is too slow)
- o A NT-like GL 3d Maze, where you are inside the maze
- o A NT-like GL wobbling Text (OS by default like flag)
- o NT-like GL FlowerBox spring and Flying Objects
- o A GL 4d ico where the 6 4D "platonic" objects "roll" around in 3d space.
- o GL modes based on demos: isosurf, reflect, bounce, stex3d
- o KitCat (R) clock mode (based on X11 catclock, a version of xclock) where
- the cat clock floats around the screen like "dclock" mode does. Colors
- of cat clock could be picked like nose-guy in "nose" mode.
- o Lottery with bouncing numbered balls like PowerBall.
- o A simple set of 2d geometric shapes that morph into one another whilst
- colour cycling. So say you start with a rectangle that morphs into a
- circle (leaving a small trail like Qix) that morphs into a triangle
- that morphs into a polygon that morphs into a rectangle, etc. All the
- while you have movement and colour cycling like Qix. If the trail is to
- large then things could become messy, but if too short then you loose the
- history element.
- o A simple bouncing ball on a chess board. The ball is a silver
- ray-traced/rendered globe. The chess board is a series of black and
- white squares. Each black square is gold veined marble with the gold
- glinting. Each white square is a textured surface (like little bumps, or
- ridges). The whole sceen is lit from two light sources (either fixed or
- moving). As the ball bounces it reflects like a mirror what is around it.
- o A variant of the above whould be to hold that ball still in the centre of
- the screen and move a randomly chosen bitmap around the ball.
- o The above could also have embossed on standout lettering added (say a
- single word like Linux). The lettering could either be stationary or
- float around the ball in orbit a bit like the the Universal studios logo
- where the Universal name revolves around a picture of the earth.
- o Take pipes and add the constantly moving view point that you get with
- rock so the mass of pipes seems to revolve and rotate around a moving
- point in space.
- o Make the little man in Nose seem to carve the letters of the message into
- rock, or paint them on the screen.
- o Make marquee use 3d extruded text that can be texture mapped and seem to
- zoom into and out of the screen with the zomm source point drifting
- around the screen at random
- o Make puzzle take the present desktop image, invert it and shuffle the
- pieces then put the whole things back. Once it has reassembled the
- desktop you could have the image flip top over bottom as it receeds into
- the screen, only to have a new randomly shuffled version of the desktop
- flip back out.
- o Use the spheres generated in sphere to draw molocules on the screen,
- colour coding for the various types of atom present. A limit on the size
- of each sphere would be needed. The spheres could be joined by simple
- white lines. If you are feeling adventurious you could make it seem to
- rotate in space so all parts of the molocule could be seen.
- o In shape change things so that the shapes appear to be extruded from a
- random point on the screen. You could aslo have a number of shapes be
- extruded, each from its own origin, only to shrink back into the screen
- again. Each time a shape shrinks back into the screen the origin would
- move and a new shape would be choosen.
- o When the screensaver is started have curtains drawn accross the desktop
- at a medium pace, a second or twos pause then the curtain a pulled open
- quickly to reveal a bitmaped image in place of the desktop. This cycles
- with a different image each time.
- o In pyro have the fireworks appear to zoom from a randomly choose point on
- the screen. This would give the effect of the display being seen from
- above.
-
- PLEASE NOTE:
- -----------
- I _REALLY_ hate to turn down contributions... I will try to consider
- all submissions. Some things on new modes that bother me are:
- Did not black out the screen when they start. I do not like people
- to see what I am doing. :^|
- Did not work in the little window or buggy.
- Is too similar mode to a mode that already exists. (Maybe an option could
- be added on an existing mode?).
- Many people complained about the mode.
- Just not enough randomness or is not interesting enough.
- No multiscreen support.
- But I labor over them (in a haphazard fashion) and they usually are
- released eventually. (If they are in assembler I would definitely need
- a working example and all the binaries and libraries to get it to run.)
