Full Version: Tiles and tile maps

Hi James,

I have not studied the node, but made some observations:
Formation takes about 30 seconds +/-.
Apply yields "exception occurred, line 528", and geometry vanishes when node editor window is closed."
But I was able to save the geometry to a .3dm at about 30 seconds+, while node was open.

Note: Slot of a basic math node is remove-able by right clicking on dot.
I need to learn meaning of wire colors...

Hi Brian,

<< Formation takes about 30 seconds +/-......exception occurred, line 528>>

That's odd...For me node generates result in 8 seconds, without error message.
I wonder if someone else might run this nod file and see if issue is repeated:
http://moi3d.com/forum/index.php?webtag=MOI&msg=8663.14

<<and geometry vanishes when node editor window is closed>>

That's true for all (or most) nod files. You need to click "Apply" button to bake out geometry, otherwise it is a preview only.

<< I need to learn meaning of wire colors...>>
Greenish = numbers
Magenta = points
Yellow = objects

Hi Brian,

I have uploaded a revised version of file (attached)
that is reduced in file size by more than a third,
though it does not run any faster (still 8 seconds for me).

Please try, and if error persists, please take screen grab
of error message, so that I might ascertain in which node
the line 528 exception lies.

Thanks
James

Hi James,
Time is still about 30 seconds, on my very good Windows computer, with lots of memory and SSD drive.
Apply causes exception, copy attached.
Possiby my nodeeditor setup is different than yours. (?)
File is ~4,144 kb.

Hi James
After nap, here is the exception.
Copied your extensions. Construct2, max_subdiv..., and basicFunctions slightly different.
Same 30 seconds, same exception upon apply.

Hi, James,

I had some trouble running the nod, but after copying your extension folder, all works properly.
Takes about 7 seconds.

Mike.

I tried to reproduce this error using extensions files from James' post.
Everything works good for me. I tested this node with the last NE release (v.0.97) and with v.0.98 (not released yet).

Very weird.
I renamed nodeeditor directory, and reinstalled version 0.97 to a new nodeeditor directory, and loaded Jame's extension subdirectory.
Same 30 second, error message.
(One time MoI crashed.)


Also tried computer reboot.

Tried loading nod from shortcut key, same result.

Hi Brian,
Right now I tested this node with NE 0.95, 0.97, 0.98 using Win and Mac versions. ~5 seconds. No errors on Apply.
Try to rename moi.ini file and run MoI with default settings.

Thank you Max.

I saved my current Moi.ini file, by renaming it.
I was unable, so far, to locate default Moi.ini, but saw one called MarvsMoi.ini, from 2015, and renamed it Moi.ini.

Success running the truchetSweep3 nod, about 6 seconds., and apply works, 0.97 version.

So something in my previous moi.ini file causes the previous failure...

OK, reverted to my moi.ini file that caused the problem.
My mesh angle was set to 1, (very low).
Changed mesh angle to 15, and now the truchetSweep3 nod works just fine.
(Maybe caused a memory problem with too low a mesh?)

Hi Brian, yes a mesh angle of 1 degree will generate very dense display meshes. That would make it likely to run out of memory when dealing with more complex geometry and also take quite a bit more time as well.

Hi Brian,

I set angle to 1 and reproduced this error. I'll add a couple of checks in Output node to avoid this error, but first I'll test NE with upcoming MoI v4.
Also it seems that mesh angle affects on factories performance, so it will be better to use larger values with nodeeditor.

Under MoI4, my incomplete draft 2D truchet tile (.js) script is lightning fast, with no edge "flicker". :-)

Hi Brian, yeah that will be because of the change in threading model for how scripts are run. In MoI v3 scripts were run in a separate process and used inter-process communication with MoI.exe to retrieve properties and such. That has a fair amount of overhead but it also made it difficult for an errant script to lock up MoI because it could be torn down any time by killing the worker process. In V4 the .js script file for a command is run on the main thread so there's no interprocess communication (same as if in V3 you moved your code over to the .htm file) so a lot less overhead, but it's also easier for it to lock things up if it doesn't behave well like if it just churns away continuously in a loop too much.

Using Notepad++ only, I just lost 1.5 hours work on my draft script documentation, despite multiple saves :-(
And I was doing such a good job too.
