Hi
I have been looking at your site to solve my problem of large data processing. Usually I have made use of Octave in this respect, but some of the functions on Octave are not up to the standard of MATLAB, (see website [https://uk.mathworks.com/matlabcentral/fileexchange/27123-earth-sized-sphere-with-topography](https://uk.mathworks.com/matlabcentral/fileexchange/27123-earth-sized-sphere-with-topography)). Does your graphics engine have that appropriate power and accuracy? I have in the past used OpenGL with C++ code calls, but wondering if your approach is suitable,
I look forward to your reply.

Are you taking about the accuracy of the 3D graphics?

P3D, is (mostly?) written in OpenGL - but I donât know how it compares to other engines out there. However, it might be easier to get setup compared to other engines. Whatâs your use case?
