Research of Terrain Model Transformation and Processing Technology Based on Node Transformation

In the three-dimensional terrain model construction, a lot of work is to modify the partial area of the discontinuous portion of the model, augmenting the descriptions of the detail and the authenticity of the model. In view of this, this paper mainly studied the influence of node transformation on terrain model. And combined with the primary technology of node transformation, the paper also analyzed the application of node transformation on a certain terrain model. The result indicates that: using node transformation technology can effectively develop the complexity and authenticity of the model, enhance the sense of immersion in the VR environment.
