Subject of Research. The paper presents the analysis of basic methods for generation of landscape maps taken as a basis for software module development intended for creation and study of models of environmental objects. Method. To achieve the synergistic effect, we proposed hybrid approach representing a mixture of two methods for construction of landscape mesh and textures: Voronoi diagrams and the algorithm of diamond-square. Main Results. The stages are defined; the conditions and requirements for the construction and visualization of landscape maps are formulated; a mathematical model of the surrounding space visualization is developed. The procedure of objects recognition from real photographs of the Buzuluk pine forest surroundings is presented; the result of the corresponding three-dimensional scene visualization is given. The analysis of CPU and RAM resource consumption showed the advantages of the hybrid approach compared to the application of Voronoi diagram or diamond-square algorithm separately. The hybrid approach implementation for adaptive landscape generation has reduced the requirements for productive capacity and computer resources. It is concluded that the developed mathematical model and algorithm can carry out high-quality modeling of realistic three-dimensional images of various objects based on two-dimensional images. Practical Relevance. The software module is integrated into a digital educational platform and enables any student to explore the possibilities of a real and key for the industry area of the landscape in the context of an online course, effectively preparing for the implementation of professional tasks in the future.
