Abstract

Nowadays many scientific 3D models of wood are available. These models are suitable only for simulation of physical fields movements in wood but not for educational purposes especially demonstration of microscopic structure of wood.3D structure of ring-porous hardwood species was created. European ash (Faraxinus excelsior L.) was selected due to its relatively simple wood structure than other wood species within ring-porous group. The model was created by manual modelling process in Rhinoceros 4.0 that is a software for visualization and modelling. Microslides were prepared from sample of ash to take micro photos that were used as a visual source for modelling. Beside these pictures made by authors of this paper other microphotos from wood anatomy publications were used. Created 3D model of ash is a VRML object (Virtual Reality Modelling Language). This format is available to viewing and presentation with severe freeware VRML browsers. These VRML browsers are available as a plug-in for standard internet browsers or as standalone VRML browsers. The model is useful for studying and teaching microscopic structure of ring‑porous hardwood species. It was created such a way to be as exact copy of original anatomical structure of ash wood as possible. The paper may be used as a cue for other authors to create their own 3D models of different wood kinds.
