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.
