[X3D-Public] Problem in X3D

Hi Inaki,

there are two establishes coordinate systems in computer graphics. Yours (z=up, xy=ground) is typically used in CAD, where folks started with thinking of floor plans as x-y-coordinates, while traditionally modelers (and vrml, x3d) used the other (y=up, xz=ground), thinking of x-y-coordinates as screen- / pixel-coordinates, while z became the depth (pointing from the screen towards the observer). Most CAD and other software allows you to either keep or swap the axes when exporting. If yours doesn't, Blender is a free modeler importing lots of 3d model formats and exporting, among others, to x3d and vrml, including the options to swap axes as needed in your case.

Cheers, Lars.
