Our master thesis deals with computer graphics, more exactly techniques for creation of outdoor
environments. We have concentrated upon studying, comparing and testing of various
methods for visualizing of vegetation with pictorial boards, so-called billboards, and polygon
models. The tool for this has been Crystal Space, an open source program for development of
games, supplied with a plugin created by us. Into that plugin we have implemented techniques
for setting out trees and other types of plants, represented by billboards or polygon models,
inside an area on a landscape surface. In addition we have implemented a technique for transition
between a polygon model and a billboard in form of a turning picture board. Our tests
have demonstrated a turning picture board to be the best among the billboard types and also
that transition far away from an observer, between a polygon model and a turning picture
board, can be made invisible with the blending transition technique we have implemented.
