I am a PhD student in the field of scientific computing (fluid mechanics) and have been working with Blender for quite a while now (see e.g. here).
Now I’m again using Blender for pre-processing but my main code is running in double precision, whereas Blender only knows single precission. Thus my question is how difficult it would be to convert Blender to use double precision. Due to the nature of my work I only need the modelling tools to run with doubles. That means that the position of vertices and normals are saved in doubles. I suspect that I would need to write a new in/output function for a double precision file type. So I’m rather wondering about the rest of the program.
Also if there are others that are interested in such a feature/fork let me know. Possible colaborators raise your hands as well.
