For a moment, I thought that Damyan's ignore-unknown-ops.patch
would be somewhat related and tried something looking like:
--- dizzy-0.3.orig/lib/Dizzy/Perl2GLSL.pm
+++ dizzy-0.3/lib/Dizzy/Perl2GLSL.pm
@@ -50,11 +50,7 @@
return ["glob", $pad->NAME, $pad];
}
} elsif ($optype eq "OP") {
- if ($op->name eq "padsv") {
- return "var" . $op->targ;
- } else {
- return ();
- }
+ return ();
} elsif ($optype eq "COP") {
return ();
}
however this leads nowhere and running the program now results
in:
$ dizzy

UNKNOWN_padsv_store_OP;
float retval = ((sin((3.14159265358979 / (0.0001 + (2. * )))) / 2.) +
0.5); gl_FragColor = vec4(vec3(retval), 1.0); }
Died at /usr/share/perl5/Dizzy/TextureGenerator.pm line 135.
The further issues and resurgence of UNKNOWN_padsv_store_OP
suggest I may not have solved much. Part of the issue might
require insights from people more at ease with OpenGL than I am.
In hope this helps moving forwards,
