A new available method——procedurally generation method and its animation are given in this paper. Marcov sequence theorem is used to solve the static obstacle avoiding problem in Computer Animation and Robotics, so as to generate the walking route, render the in-door floor texture, as the result, the authors give the abasing procedure animation which is convenient to preview and compare the effects. This method is highly realistic, easy to express continuation and tendency in texture generation, the authors also give the method to deal with the difficulty to adjust the parameter as well as the huge computation.
