Voxel-Based Terrain Generation Using Scalar Perturbation Functions
Sergei I. Vyatkin, S. Dolgovesov, Sb Ras · 2003
The problem of real-time photorealistic imaging of digital terrain is discussed. New technique for specifying digital terrain by scalar perturbation functions without its approximation by polygons is considered. A recursive algorithm for object space subdivision with masking of invisible surfaces and an effective technique of projective transformation for perspective imaging are proposed. The possibility to visualize photo-realistic terrain is shown. Examples of images obtained by modeling the work of the algorithm with elevation map of defining the digital terrain are presented.
