Abstract
The invention discloses a method for adjusting model transparency, which comprises the following steps: step 1: selecting a model to be processed, manually selecting a target model, and automatically performing transparent processing on other models except the target model by software, wherein only a wire frame of a building is reserved, so that the actual position of the target model in the whole model can be conveniently checked; step 2, dynamically determining the position of a target model according to the movement condition of the position of the scene camera, wherein the position of the target model is in a visible area of the scene camera; step 3, automatically selecting a target model according to the dynamic data of the target model, and performing transparent processing on other models except the target model; according to the invention, through automatically judging the target model, other models which shield the target model are transparently processed, so that a user can determine and check the target model more quickly, and user operation is reduced.
Description
Technical Field
The invention relates to the technical field of software processing, in particular to a method for adjusting model transparency.
Background
With the development of software technology, three-dimensional visual display of data is rapidly developed according to the intuitiveness and convenience of data display. In the fields of smart cities, smart communities, smart factories and the like, three-dimensional visualization of data is indispensable.
In application scenes such as smart cities, smart communities, smart factories and the like, three-dimensional modeling of buildings is the basis of three-dimensional visualization. Due to the fact that the building structure is complex, and various equipment and facilities are attached to the building, when a user views the building, the problem that the target model is shielded by other models often occurs.
The existing processing method usually realizes the display of the target model through user interaction in modes of rotating the model, moving a scene camera and the like, and has complex operation and time consumption.
Disclosure of Invention
In view of the above, the present invention provides a method for adjusting model transparency,
in order to achieve the purpose, the invention adopts the following technical scheme:
a method of adjusting transparency of a model, comprising the steps of:
step 1: selecting a model to be processed, manually selecting a target model, and automatically performing transparent processing on other models except the target model by software, wherein only a wire frame of a building is reserved, so that the actual position of the target model in the whole model can be conveniently checked;
step 2, dynamically determining the position of a target model according to the movement condition of the position of the scene camera, and performing transparent processing on other models in a visible area of the scene camera;
and 3, automatically selecting the target model according to the dynamic data of the target model, and performing transparent processing on other models except the target model.
Preferably, the step 1 further comprises: the transparency treatment also comprises the step of adjusting the transparency, wherein the transparency is a value between 0 and 100 percent.
Preferably, when viewing the live-action mode of the model, the transparency of the model is 0; the preferred model transparency initial value is 30% when looking at the perspective mode of the model.
Preferably, in the step 2, the position of the target model is dynamically determined according to the movement condition of the position of the scene camera, and other models are transparently processed in the visible area of the scene camera. Models outside the visible region are not processed to reduce the resources consumed by re-rendering.
According to the technical scheme, the invention discloses the method for adjusting the model transparency, and other models which shield the target model are transparently processed by automatically judging the target model, so that a user can determine and check the target model more quickly, and the user operation is reduced.
