Time-varying texels (TVTs) simulate the withering dynamics of grassland. TVTs employ a hybrid texel-and-points scheme, allowing the volume models to handle time-varying simulations. The modeling of grass carries out physically based calculations on the point-based structure. These calculations express the geometric deformation of each grass blade while providing a basis for further transformation of the desired texel array. The material-synthesis phase generates a complete color withering space from only sparse image samples. In addition, an interleaving algorithm achieves the best performance for TVT construction by clustering the precomputed simple TVT samples at a lower density to compose comprehensive models. Experimental results show that this approach effectively simulates withering. This video shows a simulation that efficiently and realistically renders the detailed dynamics of withering grass.
