Thinning trainer based on forest-growth model, virtual reality and computer-aided virtual environment

Abstract

Immersive virtual reality is applied in many human activities. This virtual reality can be used as a training tool for thinning operations in forests. The aim of this study is to describe the complex solution of Thinning Trainer, that we developed. This system uses the SIBYLA growth model for predicting forest-growth development. The model, based on Virtual Reality Modeling Language, was chosen as a virtual reality environment. The CAVE Automatic Virtual Environment was implemented as a hardware tool for the Thinning Trainer, offering an immersive virtual reality of the forest for the users. Mutual connection of hardware, virtual reality and the SIBYLA growth model is established using a software solution called Caveman. Fully automatic system provides users with the possibility to interact and experiment with a virtual forest.
