3D modelling
by  Dr. Stig L. Bardage

A methodology for computerised 3D reconstruction and visualisation of wood fibres has been developed within the Wood Ultrastructure Research Centre. 3D reconstructions are generated from stacks of micrographs obtained from serial sectionings of wood fibres. The micrographs are processed and integrated in a computerised CAD/NURBS-modelling system, which produces 3D models consisting of surfaces or volumetric bodies. The 3D models can be moved in the X, Y and Z directions allowing tilts and rotations. This freedom of manipulation allows the examination of a model from different angles. The models can also be digitally sectioned, dismembered or deformed, and provide spatial and volumetric measurement data. Norway spruce wood and pulp fibres are currently being modelled. 3D modelling will hopefully become a useful tool in the study of wood ultrastrucuture.
