I'm trying to solve patch coloring inconsistencies between
Matlab and
Octave. Depending on options to OpenGL I can get the
bi-linear
interpolation to run on either one of the main diagonals and
I want to know
which one Matlab used. Could someone run the following test
script and
then send back a png of the output?
v = [0 0 0;1 0 0;1 1 0;0 1 0];
f = [1 2 3 4];
fvc = [1 0 0;0 1 0;1 0 1;1 1 0];
h = patch ('Vertices',v,'Faces',f,'FaceVertexCData',fvc,
'FaceColor','flat','EdgeColor','flat',
'Marker','o','MarkerFaceColor','flat')
set (h, 'facecolor', 'interp');
print -dpng tst_patch.png
Cheers,
Rik
The png is attached.

On linux, ML R2012a, Interpolation is done along the other
diagonal. See attached png.

Might the difference be due to differences in the OpemGL
implementations?

Maybe it is a difference in face ordering? Does the coloring change
to a different diagonal if you do
set (h, 'faces', [4 3 2 1])
I think the documentation says that it shouldn't make a difference,
but I'm seeing one in Octave and so maybe there is one in Matlab as
well.
