Since you are using Xj3D, you should be interested in investigating XSL
for your format translations, which is easier to implement over X3D
than javacc or other BNFish parser generators.
Also, if there are problems building from cvs, check with the source
alias [EMAIL PROTECTED]
In general, the vrml97 core for x3dview, vrml97viewer, vrmlet, and many
other applications, implements a frame locked time sensor. Implementing
one abstract interpolator driven by the sensor itself which directly
operates on the vrml97 formatted data vrmlly and doing the arithmetic
vrml-java3d translations in the respective node specializations (
Transform, Viewpoint etc, ) was more likely to be self synchronized,
than implementing the same-but-different vrml97 analogs with location
based behaviors. Therefore, if you shake the j3d tree for interpolator
behaviors, none will fall off.
