Paper Abstract:
|
Rendering of large dynamic scenes with a convincing level of realism is a challenging problem of computer graphics.
One of the promising approaches to rendering such scenes is a simplification of models and the use of multiresolution
series of models with levels of detail (LOD) appropriate for the current view-dependent context. Nowadays, different
simplification techniques, including hierarchical level of details (HLOD), have been proposed and widely applied.
However, these techniques face dramatic difficulties when scenes undergo modifications. Known attempts of their
adaptation for dynamic scenes have not resulted in significant progress. In the paper an alternative approach to rendering
pseudo-dynamic scenes is presented. Such scenes have numerous industrial applications, in particular, visual
spatial-temporal modeling of complex construction projects, city infrastructure programs, and machinery assembly
production. A concept of hierarchical dynamic levels of details (HDLOD) is introduced and complementary methods for
generation of HDLODs and their visualization are proposed. The results of computational experiments are also presented. |
