It really depends - a recent example I had was trying to implement the DPMO paper (a signed distance field to mesh algorithm), and one of the steps is "compute the plane of best fit with these points and project this other point onto it." Not a particularly long piece of code, but long enough that my local DeepSeek model was able to meaningfully save time for me. http://www.sccg.sk/~chalmo/GM/SM02ob.pdf http://www.sccg.sk/~chalmo/GM/SM02ob.pdf
