Re: Applying texture map of image to object using Octave 5.1 error

yes it was uint8 and 1024x1024x3 and im2double did fix it thanks!

I believe it's used as a variable to the image.

 

Yes, "original" contains pixels data, but depending on the original jpg file, those data can be "single", "uint16" ... and Octave only supports "uint8" and "double" data for textures. Hence my question: what does "class (original)" return?

If, as I'd bet, this returns anything but "uint8" or "double", then you can probably cast your data using "im2double" e.g. 

figure ();
im = im2double (imread ("my_image_file.jpg"));
[X,Y,Z] = ellipsoid (0,0,0,10,10,10);
hs = surf (X, Y, Z, "FaceColor", "texturemap", "CData", im);
