... In /data/data/com.termux/files/home/povray31/source/unix/makefile I changed
the CFLAGS to:
CFLAGS = -fno-builtin-sin -fno-builtin-cos -O6 -c -ansi
-DCOMPILER_VER=\".`uname`.$(CC)\" -DPOV_LIB_DIR=\"$(POVLIBDIR)\" $(SRCINC)
$(LIBPNGINC) $(ZLIBINC)
... and adapted the libpng include and lib directives
PNGDIR = $(SRCDIR)/libpng
LIBPNGINC = -I$(PNGDIR)
LIBPNGLIB = $(PNGDIR)/libpng.a
Next, I built libpng.a and povray:
$ cd ../libpng
$ make -f scripts/makefile.lnx
$ make -j5 newunix

Slick! 25 seconds to render and only 50% of your battery. ;)

Was POVing the hole day on the 4 cores, temperature was around 44 degrees:
$ termux-battery-status
{
"health": "GOOD",
"percentage": 78,
"plugged": "PLUGGED_USB",
"status": "CHARGING",
"temperature": 44.100000381469727
}

If you were using 3.1g, it was only a single core.

Oki, I just ran 4 instances of 3.1g with skyvase.pov on 4 terminals:
$ while [ true ]; do ssh nexus4 povray +Iskyvase.pov; done

I've been doing the same with my phones. You can do more things with root access
though like run an sshd server.
Here's stuff I did with Povray 3.7 on my phones (and other devices):

Oooh. So I might be able to do something sick like run 3.7 on my Surface RT?
That would be crazy. That totally needs to be in the Windows Store. :)

Windows RT. I don't know if Microsoft fixed that though.
From 2013:
http://www.xda-developers.com/how-to-compile-and-port-win32-apps-for-windows-rt/
Well, let us know if it's still possible.

Right - I think that only works if you're running 8, not 8.1
> Well, let us know if it's still possible.
If I can figure out how to downgrade to 8 and then jailbreak it, then I might be
able to get it to work. I'll look into it (again) ;)

https://github.com/sdrausty/TermuxPovray works on my smartphone. I can raytrace
the Apollo moon landings, and the Titan moon landings, and more on my smart
telephone. Can you do this, too?
