Аннотация
The paper focuses on the visualization of vegetation arrays within virtual environment systems through a novel type of virtual object known as multiplicable point cloud (MPC). It addresses the challenge of adapting virtual vegetation samples, derived from 3D scans of real natural objects, to the MPC-format. The research highlights key discrepancies between these samples and the MPC-format, and presents a method to resolve these issues using the open-source CloudCompare software. Additionally, the paper proposes an output file format for the adapted virtual samples, utilizing a straightforward and easily interpretable PLY-syntax (Polygon File Format). Under the approbation of the proposed solutions, the adaptation and multiobject visualization of various virtual samples of tree- and grass-like plants were conducted. The results of the approbation affirm the expediency of the proposed method and approach, as well as their potential to effectively enhance the realism of virtual environments.
