Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] At present, when browsing a BIM model in a web browser, zooming and panning are generally used for position positioning. To locate a certain position, repeated operations need to be performed many times, and this positioning method of zooming and panning cannot track the camera (observation Point) movement direction and trajectory, and the positional relationship information between the camera (observation point) and the grid cannot be obtained directly, where the camera (observation point) is the moving point of the operator's mouse on the display screen.

[0021] The following is an example of viewing a certain component in a specific area in the BIM model to illustrate in detail.

[0022] For viewing the components in a certain area in the BIM model, the existing method is to continuously operate the camera (observation point) to zoo...

Abstract

The invention discloses a method for correctly positioning observation points during BIM model browsing in Web browsers. According to the method, when a BIM model is browsed in a Web browser, displayof a two-dimensional planar thumbnail is added at the lower left corner of the Web browser; the two-dimensional planar thumbnail is a two-dimensional planar thumbnail corresponding to a floor where anobservation point is located in a three-dimensional space of the BIM model; and by utilizing the two-dimensional planar thumbnail, the observation point can be rapidly and correctly positioned.

Description

technical field [0001] The invention relates to the field of computer applications, and more specifically relates to a method for accurately locating observation points when browsing a BIM model in a Web browser. Background technique [0002] The BIM (Building Information Modeling) model is an emerging in the construction industry at present. It can be used in the information-based three-dimensional auxiliary tool for the management of the whole life cycle of the building. It is widely used in all stages of the construction management of the building. In various information management methods based on BIM models, no matter what kind of information management requirements are based on, browsing the 3D BIM model is a commonly used important step when using the 3D BIM model in the web browser of a personal computer. However, since the browsing process involves arbitrary operations with 6 degrees of freedom (movement and rotation of XZY axes) at any point in the three-dimensiona...
