I found a rather trivial but nasty bug (T71137) in splines interpolation in Blender. I think I know how to fix it, but I can’t find the code.
This bug occurs in the computation of an extrusion in a 3D curve (maybe also in 2D curve, but it is not noticeable), in particular when computing the direction for the extrusion of the interpolated points in the spline.
Does anyone know where in the code base I should look?
Hi, thanks for reporting. I haven’t looked myself, but one way of finding out would be to pause the debugger while extruding, and then have a look at the call stack.
I can help you on blender.chat (channel #blender-coders) if you have questions regarding building/debugging. The bug you reported looks like a good first task to solve to start contributing to blender source code…
