Hello everyone, I'm to the newsgroup. I'm having some troubles with the
megapov patch. I downloaded it yesterday, and installed it. I'm trying to
use the isosurfaces so I went to http://www.econym.demon.co.uk/isotut/ to
learn about them. I took this demo from that site:
#version unofficial MegaPov 0.7;
camera { location <2, 1, -5> look_at <0, 0, 0> angle 60}
sky_sphere { pigment {
gradient y
color_map { [0.0 color blue 0.6] [1.0 color rgb 1] }
}
}
light_source {<-100,200,-100> colour rgb 1}
#declare R = 2;
// ----------------------------------------
isosurface {
function { x*x + y +z*z - 1 }
accuracy 0.001
contained_by{sphere{0,R}}
pigment {rgb .9}
finish {phong 0.5 phong_size 10}
}
sphere {0,R pigment {rgbt <1,0,0,0.9>}}
But when I run it I get "returned from renderer (non-zero return value)" I
figured since it was the demo from the site that it should work. Why am I
getting this error and how can I fix it? Any help would be greatly
appreciated.

I don't have time to try out your code right now, but I don't see any
obvious problems with that code. However, if you just want isosurfaces,
I'd suggest you use the POV 3.5 beta.

How did you installed megapov patch? I get same error, when I run this
code in
official POV-Ray version (3.1). You probably started official version.
What says messages pane? Does it mention megapov (unofficial version, etc)?

megapov.exe (version 0.7) needs to be in the same folder as pvengine.exe,
the bin subfolder of POV-Ray; other than that I have no other idea about it,
just wanted to speak up to see if that was done.

I installed the megapov patch the exact way from the instructions. Which is
basically to put the megapov.exe in the bin folder of the povray3.1
directory. So to answer your question, yes, I ran the megapov.exe from the
same folder as the pvengine.exe. I did install the new 3.5 beta, and the
isosurface works great, my function isn't visible, but that's my problem,
and not one of the program. My next step is to reinstall povray 3.1g to see
if that clears up the problem, any other suggestions as to why the megapov
patch isn't working would be greatly appreciated. Thank you all for your
help

I have seen this error occur before. I always suspected that there was some extraneous
character that I was cutting-and-pasting in.
Retyping the code into a new source, usually fixes the problem. However, when I just
cut-and-pasted your sample, it rendered fine
here.
