Development news - more NURBS: interpolators, VRML 97 compatibility

Implementation of NURBS is progressing very nicely. In addition to previously announced nodes (rendered curves and surfaces: NurbsPatchSurface and NurbsCurve), we now also handle X3D NURBS interpolators: NurbsPositionInterpolator, NurbsSurfaceInterpolator, NurbsOrientationInterpolator. Using them you can animate movement of objects and viewpoints along the NURBS curves and surfaces.

Also basic VRML 97 NURBS nodes are implemented, for compatibility.

Up-to-date documentation about supported NURBS nodes is here. Some demo scenes are inside kambi_vrml_test_suite in SVN, see e.g. nurbs_curve_interpolators.x3dv and nurbs_surface_interpolator.x3dv.

You can try the new features by using the nightly builds of view3dscene. Or, of course, you can wait for the next stable view3dscene 3.5 release — later this month.
