The Research On Method Of Three-Dimensional Modeling And Visualization

Constructs the mold interaction technology take the technology of virtual reality and three dimensional GIS as representative's three dimensional technology and the product appearance, fundamentally broke the humanity in the geography space information expression and the processing aspect limit, made up the geography information system in the place study data sensation and the experience insufficiency. This article discusses and studies the hypothesized geography information system on question above, which in the mold process, the simulation, and the data connection needed to solve, main work as follows: (1) Reappearance the appearance of the surveying and mapping Hua Yuan institution, simultaneously obtains the balance in the procedure data quantity and the authenticity. (2) Reading complex 3ds modules into the scene through programming, the more real reflection hypothesized environment. (3) The function on examination of collision. If expertly walks in the process, may put on the wall, put on the building, no true feeling did that do not have. In order to let in the scene the angle of view feel the obstacle the existence, in certain scope, when angle of view collision building main body can recoil. (4) The function of fog detecting. In order to further strengthen the scene the true feeling, joins the fog in the scene, outside the certain scope-building, can look in the fog is somewhat fuzzy. (5) The output of photo of the scene. In order to further strengthen the scene the true feeling, joined the photo source, and was allowed to control the photo source highly and around controls, thus realized the construction shadow. (6) Adding music in the scene. In order to create true feeling, Adding music in the scene, which is allowed to circulate.
