There is a dedicated datastructure for paths in the Path Workbench ,that should be able to handle very large amounts of data. However, as far as I know the arrow only appears when you hover over it, it is not continuously present. And it uses the FreeCAD GCode dialect, that may not be what you want....
After our discussion yesterday I looked up the handling of normals. In coin they are specified via a SoNormal node, and an accompying SoNormalBinding node. For example see the Part Workbench Viewprovider . You can extract the normals there without the need to recompute them yourself. That should giv...
I work in the field of ulta high precision mechatronics, and there both are essential. Algebra and general physical equations are the only way to understand your system and to derive a system architecture. You need know your main parameters, and how they influence the result. You need to understand ...
Making a Wire from points is not well defined. Are they straight connected or interpolated with some smooth function? Depended on that you have a few different ways currently (Highly simplified): 2 Points directly connected: Part.makeLine Many Points directly connected (closed or also not-closed): P...
Nice work! One remark: You currently hard coded the scene structure of a object into your code, where exactly the individual nodes are. This does only work for Part objects, as only those use this exact structure. Any other visualisation could use any kind of structures. Hence it makes sense to chan...
in the quote you posted, so LGPL. Which it should be, as freecad does not use any GPL sources in its bsae code. And with LGPL you are allowed to use it in closed source.
I used emscripten once and tried to compile freecad to web-assembly. The compiling of freecad base (no modules) including all dependencies worked after some fiddling, but I did not get it running correctly. Main issue was that python compiled for emscripten needed some special setup within the appli...
