Design and implementation for virtual forest scene synthesis-editing system

Abstract

Making use of the OpenGL graphics standards and technology of Virtual Reality, facing the demand of the forest management users, this paper described the principle and method for forest scene synthesis technology and put forward the design mentality of a virtual forest scene system. The virtual forest scene synthesis-editing system was developed with open source skeleton animation engine Cal3D, parametric tree modeling, quadtree technology, which was an integration of two and three dimension forest landscape simulation. The system provided many functions such as forest asset statistics, query and analysis, three dimention scene immersion roaming, entity model editing, garden planning and design and so on. At last, this synthesis-editing system was applied to construct complex sika deer habitat forest landscape, combined with multi-elements (digital terrain, animal behavior, tree, dwarf grass, etc.) modeling and rendering.
