COMPARATIVE ANALYSIS OF METHODS OF TEXTURING THREE-DIMENSIONAL EARTH ELLIPSOID BY REMOTE SENSING DATA USING OPENGL TECHNOLOGY

The paper considers the problem of effective texturing of a three-dimensional model of the Earth ellipsoid by Earth remote sensing (ERS) data using OpenGL technology. The methods of multiple texturing are considered, they allow overlaying satellite images on the background of the cartographic base with no quality loss and with consideration of geographical reference. Three main approaches to the problem are analyzed: combining multiple textures into one, creating curved surfaces for texture mapping, and limited texture mapping.
