Pattern viewer for forum threads

Here is an example:

Code: Select all

x = 4, y = 5, rule = 125/36
2bo2$obo$o2bo$o!

The pattern explodes instead of running as a 2x2 crawler in B36/S125, because it runs in B125/S36.

Build 163 is now live on conwaylife.com

Enhancements since the last released build:

• added [R]History support which extends LifeHistory features to any supported Life-like rule
  • implemented [R]History state 6 execution
• added AutoFit capability
  • added new button (top left) to toggle AutoFit
  • added hotkey shift and "f" to toggle AutoFit
  • notification displayed when AutoFit switched on or off
  • ZOOM and pan controls are locked when AutoFit is on
  • notification displayed when AutoFit on and ZOOM or pan change attempted via hotkeys, mouse wheel, or drag
• improved ZOOM
  • extended minimum ZOOM from 0.25x (-4x) to 0.0625x (-16x) and adjusted how zoom values are displayed
  • much faster rendering with ZOOM < 1
  • ZOOM via hotkeys is now centered around cell under mouse pointer
• UI updates
  • made the Zoom control always available at the top of the window
  • added Fit Zoom control
  • added toggle button for Grid Lines display
  • hide the AutoFit, Fit Zoom, Zoom and Grid Lines controls when help is displayed
  • moved timing information (hotkey "t") so it no longer overlaps Help control
  • increased the height of the standalone Viewer so the area without UI controls is square
  • background drag now scrolls help information and error list when displayed
• hotkey updates
  • shift and hotkey "." or "," will rotate left or right in 90 degree steps
  • shift and hotkey "[" or "]" will zoom in or out by a factor of 2
  • shift and hotkey "e" will set STEP to maximum (32)
  • shift and hotkey "d" will set STEP to minimum (1)
  • shift and hotkey "+" will set GPS to maximum (60)
  • shift and hotkey "-" will set GPS to minimum (1)
  • if help is open then hotkey "i" will jump to information section
• help information
  • display counts of cells in each state at pattern load
  • added colored boxes when showing colors
  • added count of color tiles
  • show when grid lines are switched on but hidden (due to non-zero ANGLE or ZOOM < 4)
  • documented the fact that "Esc" stops playback
  • [R]History rules now include state colors as well as Theme colors (since the Theme only defines states 0, 1 and 2)
• script commands
  • added support for HTML5 color names e.g. [[ COLOR ALIVE Red ]]
  • added [[ COLOR TEXT R G B ]] to set color for waypoint messages
• increased number and depth of STARS (hotkey "s") to support larger zoom out
• pattern decoder now accepts well know rule aliases (e.g. 2x2, Bugs, Gnarl, etc.)

Fixes since the last released build:

• pattern decoders
  • corrected generations rule decoding
  • rules without B or S prefixes were being read in the wrong order
  • refuse to run [R]History patterns with an invalid number of states
  • failing to decode an invalid RLE pattern could then be marked valid by another decoder
  • made the pattern decoder less lenient on files that look like Life 1.05 but aren't
  • added support for "life" as a rule name
  • fixed a crash after failing to decode an invalid multi-state pattern
  • improved validation of rule names for RLE decoder
• memory usage and performance
  • removed duplicate grid clears during startup
  • removed duplicate initialization during standalone Viewer creation
  • improved snapshot memory usage after reset
  • snapshot memory now dynamically grows to reduce GC
  • improved tile usage during snapshot restore and reset
  • when step back disabled do not allocate snapshot 0
  • fixed an issue with tile clear failing which caused extra tiles to be processed
  • only allocate the [R]History overlay for [R]History rule patterns that contain states >= 2
  • only allocate the [R]History state 6 bitmaps when pattern contains state 6 cells
• [R]History pattern fit zoom failed after grid grows
• display a more useful message when step back attempted but step back disabled with [[ NOSTEPBACK ]]
• with multiple Viewers and more than one non-library rule the rule names were incorrectly displayed
• corrected the highlight on UI items that are selected
• UI library can now draw icons on simple buttons

Here is a LifeHistory pattern showcasing the state 6 support:

Code: Select all

x = 457, y = 155, rule = LifeHistory

Here is an example:

Code: Select all

x = 4, y = 5, rule = 125/36
2bo2$obo$o2bo$o!

The pattern explodes instead of running as a 2x2 crawler in B36/S125, because it runs in B125/S36.

It works fine for me. Please check you're using Build 163 (and not Build 160).

[gmc_nxtman]

Ok, now it works fine. Thanks for fixing that, and for adding the support for gray cells!

[Scorbie]

@Chris
Thanks for the work so far on maintaining this project. Now I do see that maintaining anything needs some effort.
I am currently using an old netbook. And the main bottleneck of the lifeviewer here and my smartphone seems to be updating the canvas.(The speed doesn't get faster with more gps but it does get faster with xN.)
Can the "updating pattern" be considerably faster or does it depend on the speed of my browser rendering HTML5 canvas?
Not to criticize, but this implementation renders it faster. Maybe it contains some optimizations?
I don't think this small issue is worth too much effort, so don't waste too much time on this...

Hi Scorbie,
The implementation you linked is faster at drawing patterns that contain a small population, but slower at patterns with a large population - since in its implementation the drawing time is directly related to the number of cells that are alive or change each generation. Additionally it has a relatively small display grid (the default being 180x86 cells).

LifeViewer drawing time is constant (it's actually related to the size of the display window, which in the forum is constant). It doesn't matter how many cells are alive or changing. Nor does it matter (much) what zoom level, pan or viewing angle you have over the grid. The penalty for this design decision is that it's slower (than the implementation you reference) for small populations. The advantage is that the rendering (at least) scales incredibly well for complex patterns.

As you correctly pointed out this is a rendering issue and not a next generation computation issue. LifeViewer is probably an order of magnitude faster at next generation computation (regardless of supported rule) than the implementation you reference. This is why you can increase the STEP size (xN you reference, which is the number of generations per display update) without too much of an overall performance penalty.

I've improved the rendering speed slightly (~20% on some devices) in an upcoming build in the common case where the viewing angle is 0 and the grid doesn't need clipping to be displayed. I have a backlog item to investigate further rendering optimizations.

Thanks for the feedback, keep it coming

[Scorbie]

@Chris Real thanks for your analysis and thorough explanation!

Huh. You're right! Why didn't I think of that! Running a really complex pattern on a small grid does not feel any slower than a small pattern. And yep, that's a good reason to keep on with the current code. Thanks a lot.

LifeViewer is probably an order of magnitude faster at next generation computation (regardless of supported rule) than the implementation you reference.

Yeah, generation computation speed is real crucial or something like soup results and I'm really proud

Oh Yay! Thanks for the improvement! 20% boost in Android would eliminate the problem. In my netbook... Um... It has no hope anyway. (Sometimes it's acceptable but others, horribly slow, in case you're wondering.)

[rowett]

Can the "updating pattern" be considerably faster or does it depend on the speed of my browser rendering HTML5 canvas?

Hi Scorbie and other helpful souls,
Would you mind comparing these two builds of LifeViewer for me?

1. Original renderer here
2. New renderer here

Towards the top right of the LifeViewer window will be some timing information. In each case please Play the pattern so the generations are running and let me know the "work" time (e.g "work 4.5ms") over the first 700 generations. The timing statistics are per frame so you'll need to average it by inspection.
I'm looking to see if there's an improvement between the original and new renderers on your devices.
On my PC running Chrome the original gives me (roughly) a work time of 3.2ms and the new version gives me a work time of 1.4ms - which is a significant improvement, but I'm interested in whether this improvement is also seen on lower performance devices.

[Scorbie]

Okay, If I got it right, I am supposed to average the "Work" (in ms) over gen 0 to gen 700, right?
Here are the results:
On my Android phone: 20~30ms -> 19~22ms
On my Netbook: About 30ms -> About 20~22ms (I tested with the default wm in my distro, Enlightenment, and Xmonad that I installed today They seem to be about the same.)
So I guess it's a 1.5x increase in speed? Nice

Just one really, really quirky thing about my Netbook, not that it's an issue to be solved by Chris, but I'm just hoping if somebody knows how to address the problem.
My netbook shows the speed above... when it's okay, but often the speed plunges abruptly for an unknown reason, to about 2~3fps or work taking about 200~300ms. conky doesn't show anything suspicious, but xmobar shows a negative memory usage during the slowdown. Wonder what may be the cause.

Maybe it's too much hoping lifeviewer for a crazy slow netbook, but thanks anyway to Chris, and you saved considerable time for avid conwaylife forum members accessing from Android.

[rowett]

Yes, correct.

Perfect, many thanks for the results.

My netbook shows the speed above... when it's okay, but often the speed plunges abruptly for an unknown reason, to about 2~3fps or work taking about 200~300ms.

Would you mind sharing the specifications of your Netbook (CPU, memory, OS, browser)?

[Scorbie]

@Chris Thanks for your hard work.
Responding to your questions, the specs are:
Intel Atom CPU, and I think we bought it about 5 years ago.
1GB RAM
Bodhi Linux 32bit (Approximately Ubuntu Minimal + Enlightenment)
Pale Moon, 32bit, optimized build for Intel Atom CPU. (Basically a lighter Firefox fork, but it's still pretty heavy)
I'm not sure if this relates to the problem. When I ran your test, the CPU usage was about 40~70%, And the RAM usage was about 40%, 30% of which from Pale Moon.

[rowett]

Pale Moon, 32bit, optimized build for Intel Atom CPU. (Basically a lighter Firefox fork, but it's still pretty heavy)

I think this might be the culprit. I installed it on my Windows PC and I'm getting a horrendous slowdown on the tests intermittently which isn't there when I use real Firefox or Chrome.

[Scorbie]

Wow. Thanks a lot for your effort. Well both firefox and chrome takes ages to start and load a page... but I guess I could use that.
EDIT: Thanks. Installed firefox and chromium to verify that both works well. (They are real slow but render LifeViewer faster, at least.)

[rowett]

Build 174 is now live on conwaylife.com

Please note: you will need to refresh your browser to use the new build

Enhancements since the last released build:

• grid boundary
  • patterns that hit the large grid boundary (8192x8192 cells) are now instantly deleted in their entirety
  • new script command [[ DELETERANGE <1..16> ]] that defines how near live cells have to be to each other to be considered part of a single entity for deletion (default 3 cells)
• performance improvements
  • drawing the starfield is now 25% faster in the general case and 4x faster at ANGLE=0
  • drawing the gridlines is now 3.5x faster

Fixes since the last released build:

• RLE decoder was hanging on some invalid patterns
• removed support for LV85 format patterns

Here is an example of a spaceship hitting the grid boundary and being cleared.

How does it decide which cells are in the "same pattern" as those that hit the edge?

[muzik]

How does it decide which cells are in the "same pattern" as those that hit the edge?

Taking a guess here: it searches for matching known patterns in a database or something

No, it's much simpler than that. The description of the new DELETERANGE script command explains it reasonably well. I guess wickstretchers and spacefillers and such are going to be in big trouble...! But then, they always are when the Life grid is bounded, anyway.

[Kiran]

But then, they always are when the Life grid is bounded, anyway.

But it is fun to watch them explode!

[Kiran]

I found a bug in the edge detection script.

[rowett]

I found a bug in the edge detection script.

Thanks for the bug report.

The current implementation is limited to deleting the first 8000 or so cells of a pattern that hits the edge. I'll raise this limit (or make it dynamic) in a future build.

[rowett]

I'm in the final phases of testing the next LifeViewer public release. I'm looking for some RLE format patterns to test the new functionality. Specifically anything using:

• Alan Hensel's isotropic non-totalistic rules (e.g. B2ce3ai_S23) - see here
• 2-state totalistc Hex neighbourhood rules (e.g. B2/S34H)
• Any 2-state totalistic rule with a bounded grid definition (e.g. LifeHistory:K40*,20) - see here

Please PM me with any patterns so as to avoid cluttering up this thread.

Many thanks!

[Alexey_Nigin]

I guess the viewer should not try to open this.

[rowett]

Indeed. The new build determines the pattern is too large instantly. Test case is here.

Thanks for reporting.

[fluffykitty]

It would be nice if it could reach an integer zoom. (It's always slightly off.)
