Re: [OpenSCAD] Conway polyhedron operators
I guess
opengl32.dll
From
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Building_on_Microsoft_Windows#OpenGL
I read
OpenGL
OpenSCAD needs at least OpenGL version 2.0 to be able to correctly
render the preview using OpenCSG. It's possible to run with older
versions (e.g. the default provided by Windows which is 1.4) but the
display might differ from the expected output.
For systems that can't provide the needed OpenGL version (e.g. when
running on a VM) it's still possible to get the a more recent OpenGL
driver using the Mesa software renderer.
$ pacman -S mingw-w64-x86_64-mesa
After installing the mesa driver (default location is
C:\msys64\mingw64\bin, the driver itself is opengl32.dll), it can be
even activated by copying it into the same folder as the OpenSCAD.exe.
It's possible to enable it for the whole system by copying it to the
Windows system32 folder, replacing the old system driver. (Warning: Only
do that if you have a backup and enough knowledge how to restore files
in a broken Windows installation!)

Until I got the absolutely right Intel video drivers, I could not get the
OpenGL to run. This is where I got them, but I don't know what graphics
setup you have.

Gulp. I don't have any DLLs in my 2014.03 OpenSCAD folder. Which dll is it
again you're looking for, I can see if it's in my path.

The two 1066 KB files have the same time stamp and the two 760 KB files have
the same.
The two time stamp sets are within a minute of each other but precede the
date that I built the new hard drive for this box. So I'm not sure exactly
how they got here, but I suspect it was the installation of the intel video
drivers since I recall having a problem getting OpenSCAD to render until I
fixed those.

I will have to build a new computer from scratch to recover from this.
Thanks for trying

If you try anything, I’d recommend installing a version of Window for which AMD has working drivers.

The problem is that the AMD chip set on my motherboard is so old that
AMD stopped developing drivers for it. Just about ANY new motherboard
will have reasonable drivers at least for the next year or so.

Makes sense. However, keep in mind that OpenGL 2.0 is > 10 years old, so I would hope there would exist drivers :)

The issue for me was that there were Win 8 drivers, but not Win 8.1 drivers.

I'm on a 64bit windows 8.1 system. Those are the only opengl*.dll files
that are on the box. Slic3r has some opengl.dll files in its lib, but
that's it.
The 64bit system can handle 32bit stuff (that's what WOW64 is there for).
It's not impossible that some other file is being used in their place for
64 bit, but I'd have to have some idea what to look for.

On a 64 bit Windows system the naming is especially confusing as the 32/64 refers to different things, not neccessarily the bit-size of the installed Windows.
C:\Windows\System32 <- that is the Win32 API which IS having 64-bit DLLs inside on 64-bit Windows, so the opengl32.dll in there is 64 bit
C:\Windows\SysWOW64 <- that is the compatibility layer for 32-bit applications to run on 64-bit Windows and only exists on 64-bit Windows systems. This would have the 32 bit opengl32.dll. This DLL would be needed when running a 32bit OpenSCAD build on 64-bit Windows
I'd suggest to just try:
-
download and extract http://files.openscad.org/snapshots/OpenSCAD-2015.01.16-x86-64.zip
-
extract opengl32.dll (that's the 64-bit one) from mingw-w64-x86_64-mesa-10.2.4-1-any.pkg.tar.xz and put into the unzipped OpenSCAD folder from 2) at the same level as the openscad.exe file (just the DLL file, no subfolders or anything)
