![]() So the next step is actually knowing what/where you are going to use the 3D image. I was before this correction to my 3D plots only able to export a very small segment of the X-Y plane. I solved this issue in my 3D to 3D surface plots by automatically resizing the Z axis, depending on the values in the X and Y arrays. Otherwise you need to fix your X, Y, and Z axis so that they are represented inside a quadratic cube. If you, after the execution of the command above, retain a 3D figure that looks good, then you can proceed with exporting your 3D image. You can test this in Octave/MATLAB with this simple command: ![]() The question is relevant in whether your 3D output actually will relate to the 3D surface/mesh that you have created. The basics – axisįirst of all: when working with 3D export from Octave you need to know what kind of axis dimensions you are working with in your plot. This wasn’t at all straight forward when I set out to export 3D objects. I will here show some key points in working with Octave in relation to modelling of 3D data and saving it in a 3D data format. As always with non-commercial versions of programs we can see a certain lack of fine-tuning in the software as well as some missing functions from the commercial, licensed, version. with a license via the GNU General Public License. In simplified terms GNU Octave is the major open license version of MATLAB. Colormap/texture applied to Wavefront object format
