The invention relates to a dynamic texture
waterfall modeling method combining with multiple physical attributes, belonging to the technical field of
virtual reality science. The dynamic texture
waterfall modeling method comprises the following steps of: (1) measuring on the spot to acquire physical attribute parameters of real waterfalls in different environments, such as flow velocity, flow rate,
head drop,
terrain and
sunlight which influence the forms of the real waterfalls, and also recording video textures in corresponding states by using a
video camera; (2) extracting a plurality of
control parameters from the dynamic textures of a
waterfall model; (3) reasonably reorganizing acquired data in a
database, and building distribution models for the physical attributes through
correlation analysis; (4) determining demands according to scenes, and calculating real data inside the
database by utilizing a mapping law to obtain the dynamic textures of the waterfalls, which approac to real effect; and (5) rendering the waterfall scenes by using the dynamic textures. According to the invention, a statistic law of multiple physical attributes and the dynamic textures of the waterfalls is extracted, high-lifelike waterfall scene modeling is carried out on the waterfalls in any environmental form by utilizing statistical distribution and the traditional data, the defect of model texture
distortion brought about by ignoring physical factors in the traditional waterfall modeling is overcome and the real
simulation of the surface textures of waterfall flows driven by the physical attribute parameters is realized.
