I have an aversion to anything with boost in it though and OpenVRML doesn't seem to have been maintained since 2012. In this instance I think the compact VRML2 parser which I created should be fine, especially since kicad only needs to support a static scene. Implementing VRML1 shouldn't be difficult and for X3D I only need to support whatever is in the legacy parser. Like VRML2, X3D supports scripting and dynamic scenes and we do not need such support in kicad. Perhaps we can use Assimp to display STEP files one day - at <7MB it's not such a heavy dependency. - Cirilo > > On 5 January 2016 at 09:33, Cirilo Bernardo <[email protected]> > wrote: > > The code has already been tested with FreeCAD VRML models (which have a > > very strange construction) and has already been improved to work with the > > FreeCAD output.
