I tried everything I could think of, and then I remembered, - to make
things work, turn it off and on again. (At least I now have the latest
build).

ran it again. It didn't crash this latest version. it got the attached
error message, but although says rendering is finished, green progress
bar still undulating.

If you are doing something really big, and particularly memory intense. Which surface() will with anything large.
It can take a while for the process to actually die, while it frees up memory. (std:bad_alloc = out of memory)
Check in task manager that it has gone, or kill it.
Observe task manager for the OpenSCAD process memory use when doing big things.
Re the cache error, see Preferences/Advance, I have both cache at 8000MB, obviously system dependent.
Also, if you don't get a window, sometimes it can get mapped off screen, if you suspect that,
with no openscad.exe running, delete this registry branch.

I think Ray is playing with wood grain finishes that Marcus had issues with (under 'minkowski + mesh is not closed' earlier).
Memory may be the problem if you have a large pattern, like a full plank. (like a > 1MB png)
I wonder if anyone has played with tessellation? The tile-pattern/Escher type, not computer tessellation.
(https://en.wikipedia.org/wiki/Tessellation)
Where you could get a repeating, irregular shape, interlocking but replicating a pattern.
Like if these were stretched out
A brickwork type pattern would be easy, like interlocking wood flooring, but not natural.
Presumably a render()'ed tile is cached, repeating the pattern would have low overheads.
But in the end, it would still need to triangulate the whole?

BOSL2 recently added a texture feature which could be used to make that
kind of tessellation, but it makes it as one giant polyhedron, so you'll
still have lots of triangles and no caching. However, one polyhedron could
be very efficient since it can't intersect anything. I don't know if using
multiple tiles in the model would be more efficient. One way in which
multiple tiles would be more efficient is that the computations to
determine the tesselation would be faster, but I don't know if that matters
compared to render time.

I wonder if anyone has played with tessellation? The tile-pattern/Escher
type, not computer tessellation.
(https://en.wikipedia.org/wiki/Tessellation)
Where you could get a repeating, irregular shape, interlocking but
replicating a pattern.
Like if these were stretched out
A brickwork type pattern would be easy, like interlocking wood flooring,
but not natural.
Presumably a render()'ed tile is cached, repeating the pattern would have
low overheads.
But in the end, it would still need to triangulate the whole?

63 million facets seems quite a lot .
May be this is the reason.

Hi,
I managed to crash openscad trying to surface a large messed up png.
When I run openscad again, it opens to a blank window. I have another
older version on my backup PC, and the exe, if copied over to this pc,
runs, but my font settings, etc. are gone. I've just installed the 7/10
nightly build (windows 64), and that opens to the blank window also.
There is an scad.ini file which if renamed/not used, still gives the
white window. (but in the old backup folder, there is no ini. ) Do i
need to completely uninstall openscad, and reinstall, or it there some
other ini. type file lurking around (I'm not sure if an ini. is even
required, but there must be something that sets up the layout)?
Best wishes,
Ray

BOSL2 recently added a texture feature which could be used to make that
kind of tessellation, but it makes it as one giant polyhedron, so you'll
still have lots of triangles and no caching. However, one polyhedron could
be very efficient since it can't intersect anything. I don't know if using
multiple tiles in the model would be more efficient. One way in which
multiple tiles would be more efficient is that the computations to
determine the tesselation would be faster, but I don't know if that matters
compared to render time.

Hi,
Now got sidetracked into tessellated elephants. Had to trace a jpeg in
my cad software, dxf would not import into openscad, so converted it to
svg. attached below, as is the openscad script.
Plenty of room for improvement.
I think applying specific colours anf printing it on an inkjet would be
better, and much quicker. I'll see if it will 3d print in a couple of hours.
